New Airport Extreme kills LAN!!!

Just got my airport extreme tonight, followed the setup but every time I plug it into my LAN it kills the LAN. The LAN becomes extremely busy and NOTHING will get through.
I have tried using both the WAN port and a LAN port on the back. Any ideas on what could be going on? It has a good signal. My MBP finds it just fine.
But ALL LAN connection are dead when it is plugged. IE even hard wired connections don't work.

How have you configured the base station (AEBSn)?
I am assuming you already have a router, and you wish to use the AEBSn as a wireless bridge?
This should be configured to not distribute IP addresses and connected to your LAN via a LAN port.

New Airport Extreme: no LAN lights, base station not found

I just brought home a new Airport Extreme base station 802.11n to replace a Linksys router which I used without too much trouble (it used to boot me off occasionally, which was annoying). I want to connect to my DSL internet using an ethernet cable. There's also a PC and a Mac in the house that are wireless. However, the Airport Utility doesn't see the AEBS, I've got the classic flashing amber light, and at the back, the WAN light shows a connection to my DSL modem, but I've got no lights on my LAN ports. (I have seen them light up very briefly but they never stay on.)
I've tried resetting the modem and the base station countless times. I've reconfigured using different ethernet cables. I've disconnected the base station for over 30 minutes before powering up again. I can get a connection when I connect my modem directly to the mini. I've tried using different LAN ports to connect the base station to the computer.
What should I try next? It's a really simple setup, and all I'm trying to do is to connect to the internet.
Thanks for any suggestions.

I know you have tried a series of resets, but please try the following with your Mac Mini connected directly, using an Ethernet cable, to one of the LAN ports of your 802.11n AirPort Extreme Base Station (AEBSn), and the AEBSn's WAN port connected (via Ethernet) to the DSL modem.
Try the following, in order, until the Mac Mini is able to access the Internet:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

My LAN ports don't work on new AirPort Extreme

I just bought a new AirPort Extreme ac and for some reason my LAN ports don't work. Wireless works fine, even extended by an older version of AirPort Extreme. I tried to reset the AirPort, but it didn't help. Any help appreciated.

Defective product that needs to be exchanged, assuming you have checked Ethernet cables, etc. We have seen a few similar posts, but usually with WAN port issues.

Argh! Trying to Replace Linksys with New Airport Extreme...

Been fighting with this for hours...about ready to take the new Airport Extreme back ...Here's the deal:
I currently have a very wired and wireless 2story home professinally set up with 2 Linksys devices as the primary network and a couple previous generation airport expresses as extenders.   Due to video, audio and other systems the primary router for the network/WAN closet out in the garage needs to remain on the primary Linksys (non wifi) router. I want to replace the Linksys Wifi router (see below) that is puposely set up and has worked for several years as a double NAT config with the new Airport Extreme but i have tried duplicatiing the exact configs from the Linksys router and all the various ways you can use the Airport Express in DHCP/NAT and even in Bridge mode and it still wont work! I've never considered Linksys software easier (and definately more flexible and informative) to use than Apple until this experience! Very frustrating.... I'm being very explicit and using the typical Linksys config profiles below so as to hopefully help you translate this into specific configs i can wrangle into the Airport Extreme to make it work like the
Current Primary Network:
Current WAN Router / + 24 Port Switched LAN Network (for wired ethernet access ports used throughout house) > Linksys BEFSX41 + Linksys 24 port Switch locted in a custom built data /video / audio closet in garage
WAN IP: DHCP
LAN IP: 192.168.1.1
Subnet Mask: 255.255.255.0
Current WiFI Network > Linksys WRT160Nv2 (currently conected to the 24port switch via a hardwired ethernet wall port upstairs in my office)
Internet Connection Type: Static IP
WAN IP: 192.168.1.2
Subnet Mask: 255.255.255.0
LAN IP: 192.168.0.1
Subnet Mask: 255.255.255.0
Per config notes from the network engineer who i worked with to build this network when i built the house
"this allows the 192.168.0.x wifi device to successfully route to the 192.168.1.x wired router (and vice versa)"
My goal is to replace the Linksys WRT160Nv2 with the new Airport Extreme (whose range and ability to reach both upsatirs and outside to the beach is MUCH better) and locate it DOWNSTAIRS and connect it in the same way as the Linksys (via an ethernet port in the living room) to the same switch / router in the data closet.
I have tried to set up the new Airport Extreme to replicate this config several different ways both bridged and not bridged (including telling it to ignore the double NAT warning) with the latest.   I am pretty sure non-bridged is the right way to do it but i seem to lack a config parameter to tell the Airport Extreme to replicate the equivalent of the WRT160Nv2 settings despite trating all the submenues and options on the airport extreme set up / Airport Utility App. Do i have to telnet directly into the Airport Extreme config files to do this natively? Help!
PS - no i cannot / will not put the Airport Extreme in to replace the primary Linksys router in the data closet - there is no way it will fit or that its wifi could penetrate the EMI and insulation of all the other electronics in the data closet out in the garage and get a good connection into the house

The trick on the airport extreme is to change the DHCP .. when you change the DHCP it changes the actual IP of the AE..
So go to the setup and open the dhcp, in the network options and you can select by arrow the first two octets and replace the third.
I just posted info on this in another post..
https://discussions.apple.com/thread/5134560?tstart=30
Does this answer your question, as I am a bit unclear otherwise??
I have to say I do not like using double NAT.. it is becoming worse and worse as the amount of material on the internet that requires interactive connection increases.. you block so much by doing this.. double NAT is an issue .. not just ignore the warning.
There is no reason why you need double NAT.. you should have a single flat network. If you need to keep some things isolated from others the correct way to do it is vlan.. but you will need a better router than the old linksys to do it. And possibly a managed switch. Nowadays a managed 24 port gigabit switch is not a bad price at all.

How to improve upload speeds with new Airport Extreme?

Hi!
Just plugged in a new Airport Extreme to replace a BT HomeHub 3.0. The wi-fi download speeds have generally increased over a wider range in the house but the wi-fi upload speeds have dropped to under 1Mbps.
Speeds to laptop linked via ethernet appear fine (both up & download).
Initially thought that I may have messed-up the set-up but the fact that the wired connection works fine makes me think this is something to do with the Airport settings - a scary thought as I don't really know much about this stuff.
As range was really the reason for getting the AP Extreme I'm contemplating plugging the HomeHub back in and just trying to use the AP to extend the old HHub system rather than setting up a new AP system...
Any suggestions would be most gratefully received!
Thanks

... just a quick note to say that the appears to be resolved after a long telephone call to apple service dept (very patient - very helpful).
In my naivety I had attempted to revert back to using the homehub (3.0) router and connecting the APExtreme into one of the Ethernet LAN ports but this didn't work! So called the apple helpline & we went back to basics until it worked. One point to note that may help anyone finding themselves in a similar position...
I had followed the instruction to reset the APEBS depressing the button first whilst powered then without power and during the unit being reconnected to power supply thinking tha this would do a full restore to factory defaults (effectively undoing all the messing- around I may have done flounderinng through the settings) but it was only when I was directed to do a full reset through the Airport Utility settings [Edit\Advanced\Restore Defaults] that this worked (for me).
Download and upload speeds are now up to 93% of advertised speeds wired, & wireless with some fluctuations which appear to be network delivery related rather than anything to do with the APEBS. It's working well with an APExpress which had been struggling (intermittentlyout of range) which is connected to stereo and Apple TV.
By the way - thanks to other posts regarding importance of not connecting an audio out cable to phono sockets on the stereo (horrible sound quality) using a redundant CD channel it works great.
All-in-all, very happy with it so far.

Help!?! Can't read configuration of new Airport Extreme, Help!?! Can't read configuration of new Airport Extreme

Trying to set up to print with MacBook Pro, OSX 10.5.8, Canon MX870 series printer, and NEW AirPort Extreme. I get the message that "an error occurred while reading the confirguration (-6753)" At wit's end... tried using ethernet cable connection- MacBook Pro to Airport Extreme... same message. That was the suggestion from the Express Lane tech. That perhaps our WiFi at our physical location was interferring. Have tried ethernet cable to Airport... same. Also tried USB cable... same message. Used same MacBook Pro and Canon printer a year ago, but with an older Airport Extreme, and it worked perfectly... wirelessly. HELP please, please

Also am having problems with my roomates HP Laptop... It connects for only a few seconds/minutes then has an issue... Really shady??? Any Ideas? He is Running Windows XP

PROBLEM with new Airport Extreme

i just bought the new airport extreme and what was supposed to be a simple setup process has taken longer than 10 hours!
please help!
i have 3 computers.
2 are macs, they will be using wireless. 1 is a PC, which will be wired to the airport extreme.
the airport extreme is connected to a VOIP router, which is then connected to the DSL router.
i have always used my old airport extreme without issues, but because i want to connect the PC as well, i must ditch the airport express in favour for one with LAN ports. hence, the troublesome airport extreme.
it doesn't work.
none of my computers can recognize the new network. (even though i've established one, with passwords and everything)
the router flashes amber - internet works, but not wireless.
the router periodically flashes green - ironically, nothing works then!!!!
please help!!!
EDIT: DIAGRAM
1. WHEN IT WORKED:
INTERNET --> PROVIDER ROUTER --> VOIP ROUTER --> AIRPORT EXPRESS --> MAC 1, MAC 2 (WIRELESS)
2. WHEN IT DOESN'T WORK:
INTERNET --> PROVIDER ROUTER --> VOIP ROUTER --> AIRPORT EXTREME --> MAC 1, MAC 2 (WIRELESS), PC (WIRED)

It appears to me that you may possibly have sever conflict issues as well as maybe not having the Network confiqured correctly.
I have a 3 story OLD VICTORIAN and I am using the Old Airport Extreme Base and have expierianced NO PROBLEMS at all.
If I may suggest a different approach.
Try to start from scratch.
SHUT EVERYTHING OFF.
Run an ethernet cable from your Internet Service Providers MODEM to the WAN port of the Airport Extreme Base
Set it up DHCP and you want the Airport to distribute IP's
use the Airport setup assistant and Airport Admin Utility.
Using 2 Routers in the mix unless you have ony one the main to distribute the IP's, IF you have 2 Routers and they are both set up to distribute the IP's there is your problem.
The New Airport Extreme Base is far better then the older model and you shouldn't need another router in the mix at all to get the coverage of your entire house.
Take the Netgear clear out and use the Airport Extreme and the Expresses as you had them before. There is a very good possibility that you will need to do evrything one at a time and step by step.
Do not just plug everything in, and turn everything on and expect it to work. Do everthing step by step with all security disabled to begin with.
Be sure when you do your system reset that you start by powering up the MODEM 1st and wait for it to acquire the signal before you power up the Airport Extreme and again you must wait for it to acquire the signal. You can use the LAN Ports for anyyhing you need HARDWIRED. If you don't wait and do things in the proper order you will have problems, I can't stress enough that it must be done in the proper sequence. Have a look at the Paperwork of either the Netgear's Yellow Phamplet or the Booklet that came with the Extreme to bear out what I explained on the sequence.

Is a Happy Marriage Possible? New Airport Extreme & ADSL Modem/Router

Is a Happy Marriage Possible? New Airport Extreme & ADSL Modem/Router
1. I’m writing from a rural town in Southern Nepal, very close to India. I’m planning to create a new WI-FI network at a small monastery here. Ideally, we will have two parallel wireless networks: the first network produced by an ADSL router/modem and a second network produced by another router in “repeater” mode.
2. Earlier, someone suggested that, when I post a question, I should provide as many details as possible about the situation here. Forgive me if there is “too much information”. I have to make a trip to the US to buy new networking equipment, so I very much want to get this right. Once I return here, I’ll be pretty much stuck with whatever I get in the US.
3. The future routers will live next to each other in an office and could be linked by a cable (if this is the best route to go). We do not wish to “expand” the network (in the sense of making a larger WI-FI network), but rather wish to simply have two networks, hence one ADSL router/modem and one router with the “repeater” function (out-of-the-box without any jerry rigging). Both WI-FI signals need to travel approximately 100 (largely unobstructed) feet.
4. If my dreams come true, the second router would be an Apple Airport Extreme (AX). An Apple router would be ideal because my experience with Apple routers is happy: they are easy to set up, reliable, and secure. Moreover, we use Apple computers and iOS devices here (and the new AX has the “ac” thing which will be preferable as we replace old machines with new ones).
5. Yet, from reading posts and having my prior questions answered on this website, it may be that with an ADSL modem/router, all the ease and happiness of the Apple ecosystem is lost: while Apple routers seem to connect with each other easily, problems appear to arise when users try to inter-marry our non-Apple products with Apples.
6. Our current, super-crappy 2wire 2701hg-t (ADSL modem/router) covers the 100-foot distance without a problem when it is working and there is Ethernet flowing to us. Frequently, our connection is very bad, and I may be unfairly judging the 2wire 2701hg-t. But, based on user reviews on the America Amazon.com, the 2wire 2701hg-t is pretty terrible: first it is simply old and second, among other problems, it seems to have a poor quality power supply unit. I do observe that it frequently seems to be recycling from scratch as if it had turned off and restarted. In any case, we are replacing it since it may be about 4 or 5 years old.
7. In previous posts on this forum, “LaPastenague” responded to some of my earlier questions about AX and ADSL. Among other things, he pointed out that (1) line-attenuation may be contributing to our poor connection and (2) we must choose a modem/router that is suitable for “long lines.” I’ve looked at our current modem/router statistics page; however, there are no statistics for line-attenuation or noise. (As you will see below, my strategy is to get the “better” modem/router that is suitable for long lines.)
8. Concerning our ADSL service, these are the facts I’ve gleaned from looking at the current router’s configuration pages:
Connection Type: PPPoE
Currently, the router is configured to use WPA-PSK security.
Connection Speed: Incoming: 1024 kbps & Outgoing: 509 kbps
(The following information may be unimportant at this time.)
Broadband Link Diagnostics:
DSL Synchronization: UP
G.DMT Signal: UP
PVC Connection: UP
PPPoE Service: UP
PPP Authentication: UP
IP Connection: UP
DNS Communication: UP
9. The ISP (Nepal Telecom) doesn’t supply a modem/router; however, they do have a list of (at times ancient) hardware and hardware vendors:
http://www.ntc.net.np/internet/adsl/adsl_vendersConf.php
10. Concerning what equipment is available here, what I have observed is that generally the ADSL modem/routers for sale locally, and in the far-away capital Kathmandu, and in nearby India are often also available in the United States, but they are the cheaper, older models. I will have to buy the new equipment in the US this year. At a different institution nearby, they are using the TP-Link modem/router td-w89016 which they purchased locally, I believe.
11. Based in part on LaPastenague’s earlier advice, I want to buy the TP-LINK TD-W8980 N600 Wireless Dual Band Gigabit ADSL2+ Modem Router (2.4GHz 300Mbps+5Ghz 300Mbps, IPv6 Compatible). This appears to be the most popular ADSL device on Amazon now.
Will this modem/router work EASILY with the Airport Extreme in the manner I’ve described? That is, connecting the two with a cable and creating two WI-FI networks.
12. Also, is it generally correct that the best way to connect them is with an Ethernet cable: https://discussions.apple.com/message/23759755#23759755
13. In fact, does connecting them with a cable help alleviate some of the problems that can occur between the Apple device and the ADSL modem/router?
14. If this will work, what “mode” will the AX device be in (again, in order to have two separate networks with separate passwords)? I have heard of the “repeater”, “roaming” , and “bridge” modes.
15. Are there two levels of passwords which need to be considered? Of course, there is the network and network passwords which we create here and which will be different. But, does the Apple also have to have the ISP password like the principle ADSL modem/router?
16. To set this up, what information do I need from the ISP (e.g., passwords, IPs…)?
I think there are a lot of good reasons to use an AX router. Of course, if it is just going to be very cumbersome then, we would be loosing one of the best parts of using Apple products. So, whoever feels knowledgeable enough to reply to this post, please be sincere if you think it is better to avoid the Apple. Apple can rest assured that I will buy other things from them!
In that case, I’d likely buy a second TP-Link device to create a second network:
TL-Wa801NP [AP Mode Multi-SSID Mode AP Client Mode Repeater Mode (WDS / Universal) AP+ Bridge mode (point-to-point / point to Multi-point)].
Thank you in advance. Long live Apple!

I am not sure if there are different interfaces but my 2wire does an excellent job with line info.
I get into this from browser.. using main IP.. in my case 10.0.0.138/MDC
In your case it should be whatever the IP of the 2wire is, followed by /mdc
Give it a try.
As you can see it shows vendor and loads of info about the line.
I rate it the best domestic modem for line info.
A good modem actually albeit a lousy router.
MDC is the diagnostics and Management Console.
3. The future routers will live next to each other in an office and could be linked by a cable (if this is the best route to go). We do not wish to “expand” the network (in the sense of making a larger WI-FI network), but rather wish to simply have two networks, hence one ADSL router/modem and one router with the “repeater” function (out-of-the-box without any jerry rigging). Both WI-FI signals need to travel approximately 100 (largely unobstructed) feet.
You are not repeating.. you are simply setting up two routers which are interconnected, so one is dependent on the other.. ie one is your adsl modem router and that will take the main router function. Your second router is really not working as a router, but as wireless access point (and switch if you plug things in).
That is perfectly fine. You are not roaming in this case since both routers are running different wireless names and networks.. but they are actually using same IP range.. all devices are on the one IP network with two different wireless access points.
4. If my dreams come true, the second router would be an Apple Airport Extreme (AX).
Apple router is fine for this. Easy to configure out of the box.
5. Yet, from reading posts and having my prior questions answered on this website, it may be that with an ADSL modem/router, all the ease and happiness of the Apple ecosystem is lost: while Apple routers seem to connect with each other easily, problems appear to arise when users try to inter-marry our non-Apple products with Apples.
The problem arises when you try and interconnect using wireless extend or repeater.. you are not using wireless to extend, you are using ethernet. Wired has no issues.
11. Based in part on LaPastenague’s earlier advice, I want to buy the TP-LINK TD-W8980 N600 Wireless Dual Band Gigabit ADSL2+ Modem Router (2.4GHz 300Mbps+5Ghz 300Mbps, IPv6 Compatible). This appears to be the most popular ADSL device on Amazon now.
Will this modem/router work EASILY with the Airport Extreme in the manner I’ve described? That is, connecting the two with a cable and creating two WI-FI networks.
It is a good choice.. It should be fine considering how poor your line is.. this modem is proving to have a couple of bugs.. it does not handle torrents well but I would suggest your system is not being used for that purpose. It has some port forwarding issues. Again you are probably not going to overload it.
12. Also, is it generally correct that the best way to connect them is with an Ethernet cable: https://discussions.apple.com/message/23759755#23759755
Absolutely best.. only decent method.
14. If this will work, what “mode” will the AX device be in (again, in order to have two separate networks with separate passwords)? I have heard of the “repeater”, “roaming” , and “bridge” modes.
Bridge. Although if it gives issues there is another method, although rather complex to setup.. not something to worry about now.
15. Are there two levels of passwords which need to be considered? Of course, there is the network and network passwords which we create here and which will be different. But, does the Apple also have to have the ISP password like the principle ADSL modem/router?
Only the adsl modem has the ISP authentication.. it is the box that does the link. The TC just piggy backs.
The passwords on the TC are for its Admin, wireless and disk access.
16. To set this up, what information do I need from the ISP (e.g., passwords, IPs…)?
For ADSL you must have the PPPoE authentication username and password.
So, whoever feels knowledgeable enough to reply to this post, please be sincere if you think it is better to avoid the Apple.
hmmm.. I am biased because I see the issues not all the good stories..
The latest airport and Time Capsule seem to have a few pretty severe bugs.. if they happen to hit you, they are extremely hard to fix if you are in the middle of Nepal. And Apple service centre is a long long way away.
I cannot answer your question from the point of view of a person on the ground in remote area. If the economics of the purchase works for you, great. Go for it.
In terms of wireless coverage.. the Asus AC models or Netgear R7000 kill the Apple. Sorry but it is just fact.
See reviews here.
http://www.smallnetbuilder.com/lanwan/router-charts/bar/113-5-ghz-dn-c
That is average.. if you look at the apple router in the worst location by changing the filters, it comes out worse again.
I cannot post the URL to our local forum here.. (apple doesn't allow it). But in testing with apple clients the asus still beat Apple router soundly.
Pure wireless range is not the only consideration.. but in a mixed environment and since the wireless on the 8980N is not too bad.. then buy Apple router for apple client devices makes good sense.
Maybe the older Gen5.. or two of them.. would do a better job.. with a bit more tested and known hardware.
One thing you do need to check.
Routers from every other brand allow you to select country. Any country from anywhere in the world. Apple routers do not.
If you buy an airport in North America it is coded to North America and offers just a few countries.. USA, Canada I suppose.. what else is North America??
You cannot change it to Nepal.
To get the one for Nepal you must buy the model that covers, South Asia I guess.. I am not sure which it is.
See what the license information is for wifi in Nepal as it might be very different to US and therefore illegal for you to run it in Nepal.
If only the whole world would just bow to America.. we could all follow the FCC regs..
http://en.wikipedia.org/wiki/List_of_WLAN_channels
This only applies to the Apple.. the TP-Link etc allows you to choose Nepal or correct country regulations for wifi.
Buying modems has one tricky bit.. that the actual adsl ATM channel is different in different parts of the world. No modem is usually impossible to setup but some can be difficult if it is pre-configured for US.. this is easy to overcome generally as you can download a firmware for another locality, so you can have local settings.

I have an 2tb time capsule 802.11n Wi-Fi base station can I use this as an external hard drive and use a new airport extreme 802.11ac Wi-Fi for my wifi?

I have an 2tb time capsule 802.11n Wi-Fi base station can I use this as an external hard drive and use a new airport extreme 802.11ac Wi-Fi for my wifi?

You can use the 2 TB Time Capsule as a network drive. That means that it must connect to one of the Ethernet LAN <--> ports on the new AirPort Extreme, or connect to the network using wireless.

Gigabit ATA (IDE) NAS vs USB 2 SATA+new Airport Extreme

Hi,
I'd like to share iTunes, iPhoto and video (HDV) content between two iMacs (G5s) on a Gigabit ethernet LAN. Would also like to stream DivX and VIDEO_TS files down to a media player via Gigabit ethernet. (Looking at TViX HD M-4000P media player as Apple TV won't do DivX and VIDEO_TS)
So I'm looking for a shared disk option.
Would a Gigabit ATA (IDE) based NAS provide read/write of this type of content faster than an USB 2.0 SATA based external disk plugged into the new Airport Extreme ?
I'm considering the new LaCie Ethernet Big Disk 1TB as the gigabit NAS.
Thanks for your help,
Tony

The short answer, Yes. The choke point for the USB 2.0 SATA drive is the Airport Extreme. Because the APE does not have Gigabit connectivity your link to the USB 2.0 drive is limited to a max of 100Mbps via cable or 200Mbps (real world N) via wireless. If you have the iMacs, Gigabit NAS device and the device you're streaming to all hooked to a Gigabit network that would be faster. I would check the specs carefully on the media players and assure that they are Gigabit (also noted as 1000Tx or 802.3ab).
This is my biggest complaint with the APE is no gigabit.

Can't Configure New Airport Extreme

My new Airport EXtreme is operational and I can access the net work from both my PC and 2 Macs however I have been unable to configure the base station to move it away from 'public' status with it's factory 10.??? IP address and thus have an open network.
On initial startup with the Airport Setup Assistant on the Mac I get "An error occurred communicating with the selected base station".
I've tried all the trouble shooting re-sets and the Airport Admin Utility but with similar results. At one point on the PC I got the slighlty more informative "the base station is in soft reset mode but does not appear reachable with the IP address configuration of this computer. Make sure your computer is configured for a 192.42.249.X IP address so base station can be configured". Don't know what this means ....
All the correct DHCP settings seem to be in place but a colleague across the street with an Airport Express has no problem. I'm at a loss...

Basic principle - setup instructions are there for a reason, and if you don't follow them then the thing won't work properly What happens if you connect your cable modem to the LAN port of the Base Station:
- you bypass the router built into the Airport Base Station
- your Mac will be unable to communicate with the Base Station.
Neither is a good thing - and you need to get to the bottom of the problem causing you to have to incorrectly wire the Base Station just to give it the "appearance" it is working properly (even though it is not). Usually the solution is simple - cable the modem to the WAN port, pull power to the modem and the Base Station for a half hour, then plug power back into the modem, then plug power back into the Base Station. That's it.
Incidentally - a temporary fix is to (a) disconnect the modem from the Base Station, (b) power cycle the Base Station, and (c) restart your Mac. Your Mac will now be able to "see" and configure the Base Station. However, as soon as you are done and you plug the cable modem back into the LAN port and restart your Mac - no admin access to the Base Station will be possible.

Network Printing broken on New Airport Extreme

I have just installed a new airport extreme to my lan.. There is a network printer also attached to the lan (Xerox 6200N). Previously when I had an airport express attached, all computers connected to the network via the airport were able to access this printer... Now that I switched to the new Airport extreme -- NONE of the computers on the wireless network even "see" the printer... Computers that are physically connected can still print...
Help would be MOST apprecited.
Thanks.
Rob

No - the printer is attached to a router. The network is set up like this:
DSL modem to router
Router to Networked printer (Xerox 6200N)
Router to older G4 minitower (without airport card)
Router to new Airport extreme.
Previously the same exact network cable was attached to an airport express --- no problems printing to the printer.
Just set up the Airport extreme yesterday --- no problems with the internet but doesn't recognize printer...
(FYI - DSL is static IP --- which I need for the G4 minitower because it acts as a server for my calenndar program --- the computer then is set to share it's internet connection via the sharing preferences)
Thanks.

Proper way to mix new Airport Extreme with Airport Express, wired and wirel

I currently have several macs. Two of them have 1000 airport (macbook pro and macpro), the other 3 have 100 speed.
I have one Airport Express I'm using now. I'd like a faster setup though.
Here's how I've got it wired up now:
1. I go from my cable modem into a 10/100 Linksys wired router
2. A Net gear 10/100/1000 4-port switch is hooked to the router
3. My airport Express is hooked to the switch
4. my 4 other macs then are hard wired with regular ethernet cable to the switch.
So, my wireless is only for the device(s) that need it, and all other macs go through wires to the switch.
Now, I want to buy a new Airport Extreme to increase my wireless speed when copying files and sharing my iTunes library.
Will having the Express on the network make the Extreme jump down to 100 speed? Or, should I buy a new router, a 10/100/1000 router, and just plug the new Extreme right into it, thereby separating it technically from the slower Express/wired stuff?
I guess I won't even need the Express anymore unless I use it for my older macs that don't have the new n speed airport cards, right?
any insight would be helpful, I'd hate to buy stuff I don't need, and vice versa.

Please try taking the readings again using iStumbler's Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the Signal-to-Noise Ratio (SNR) at your iMac for the following two cases:
o Case_#1: Just the AEBSn. (Temporarily unplug the AX for this reading.)
o Case_#2: When the network is configured for WDS.
Within the Inspector, on the Properties tab, note the values for "signal" & "noise" for each of these cases. These values should be negative.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
For Case_#1, if the SNR is 20+dB, you may consider not using a WDS as this SNR value would represent decent Wi-Fi performance at your iMac's location from the AEBSn alone. If it's less than 20dB, then the WDS would be required. ... and, if this is the case, you would want to place the AX within the 20+dB range of the AEBSn to make sure it has the strongest signal to repeat.

Timed Access not working on new Airport Extreme (802.11n).

I bought a new Airport Extreme (802.11n) to use as a router for my network. The network has a mixture of Macs and PCs, using a mixture of wired and wireless connections.
I configured the security settings with on the Airport Extreme to Timed Access. I set the default setting is to No Access.
Three computers are set with "Everyday, Between 8:00am and 11:00pm"; however, when it's 11:00pm, nothing happens. The three computers continue to have access.
I know the MAC addresses I entered are correct. Does anyone know why the Timed Access is not working?

Yes, the printer was initially set the same way it always was on my old router. It used to pop right up on the list. After I switched I was getting communication errors. Ok, new setup, I wasn't worried yet. When I got to the setup window and it a new printer wasn't found I tried updating drivers. No luck. I then used the IPP mode to enter the IP address with the address on the Canon screen. It failed. I then did the same setup telling it which software from the driver list to use. It still could not see it. The odd part is that the Canon can obviously see the router as its LAN setting read active and it is receiving the IP. I have proceeded to play with every setting on the printer and it is back to factory reset. Oh, I should mention that I have also tried to use Canons network setup utility software and it can not find the connection either. So I really think this is a problem within the router. I have seen many complaints about this on other forums, but most were looking to use the usb on the print server. My Airport is nowhere near my printer and I don't want to lose my all-in-one functions. Some think hard lined ethernet is ancient, but it really is a nice setup. Fast and reliable.

New Airport Extreme (802.11n): : Port Mapping... ***???

There are two different programs I was formerly using, whereby (after following instructions) I was able to create a static IP address for every machine on my network, plus open ports 8000 and 9990-9998 respectively. But ever since upgrading to the new Airport Extreme (802.11n), it completely stopped working. To boot, I've upgraded to Leopard on one of two of the machines (the other is still using 10.3.9).
I haven't been able to figure out for the life of me, how to configure it. It's no longer as obvious where and what information to put in. All guides that would remotely help are designed for the older Airport unit, which has completely different menus in the Airport Utility.
Is there anyone out there who has experience with Dot-Tunes and/or Nicecast or similar port mapping, who has the patience to describe, in layman's terms, what steps to take to get this set up correctly again, starting with how to reassign static IPs for my machines. I will not ask a lot of questions and take up too much more of your time. I'm just frustrated after a whole day of trying to figure this out and fruitless Google and forum searches.
Thank you so much.

I'm not familiar with either Dot-Tunes or Nicecast, but the following would be the general port mapping procedure with the 802.11n AirPort Extreme Base Station (AEBSn) using the AirPort Utility. Note in this procedure you will not need to assign a static IP address for each of your host devices. Instead you will be taking advantage of the AEBSn's DHCP reservations feature.
To setup port mapping on an AEBSn, either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the host device.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the host computer>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Service: <choose the appropriate service from the Service pop-up menu>
o Public UDP Port(s): <enter the appropriate UDP port values>
o Public TCP Port(s): <enter the appropriate TCP port values>
o Private IP Address: <enter the IP address of the host server>
o Private UDP Port(s): <enter the same as Public UDP Ports or your choice>
o Private TCP Port(s): <enter the same as Public TCP Ports or your choice>
o Click "Continue"
