X-Modem + Airport Extreme = Nothing

Hi guys
I bought myself an Airport Extreme ages ago and couldn't get the bloody thing to work with the gear i had at the time, so recently i got hold of an X-Modem and still i can't get a connection to the internet, my iMac connects to the Airport just fine, i get a green light when it's connected to the X-Modem but still no internet connection, Now i must warn you, i know very little about networks and internet connections because in the past things have just worked, i currently use a BT home hub but because of this i have no iChat and a connect rate that is not constant some times its very slow and other times very fast.
Please help.

Well this is my basic setup.
DSL Modem/Router --> Airport Express (WDS Main) --> Airport Extreme (WDS Remote)
The reason that I can't move the AE to the modem is because then I will have to move my HDD (network storage) my media server into the living room and I'd rather not have all those things sitting around my TV.
I have however figured out what was happening. My modem has a DHCP server in it so I have now used that to set up all the static IP's that I need. This is also good becuase I can use the modem to forward ports. (Becuase I noticed that on the AE when it is set to remote you don't get the port mapping/forwarding options anymore)
I then went to the AX & AE and set them both t to bridge mode so that they just forward on the IP's from the modems DHCP setting.
Everything seems to be working just fine.
Seems like a bit of a waste really to have the AE there not doing anything other than forwarding on a signal but it beats getting into my roof to install another phone point.
Thanks for your help!
*PS Also the ethernet ports on the AE in WDS mode still function just fine. I have the NAS drive hooked into one and it's working.

Roadrunner Cable Modem + Airport Extreme = limited internet :(

I am having trouble gaining full internet access with my Time Warner (Roadrunner) cable modem. They use DHCP to configure TCP/IP, and I need a publicly visible static ip. I have tried many different things to get this to work, but so far nothing. Anyone know how (or if) I can get this to work?
Would be very helpful to know what Roadrunner SoCal limits with their residential service. I cannot find this on their website, and the rep I spoke with said they block nothing. I'm not sure if this is true.

The problem is that the airport extreme is "in front of" your computer. So that when Internet services (like BitTorrent) try to connect to your machine (which is expecting them), they hit the Airport first, (which is NOT expecting them)... since it doesn't know what to do with them, it throws them away.
So I know you go on to explain how to let this traffic through, but should I place the airport in front of the modem (I dont even know if this is possible)
The reason why things like WWW work, is because the Airport isn't completely brain-dead. It knows how to "follow a conversation" and it essentially eaves-drops to all outgoing connections from your computer. If your computer deliberately asks for a response, then the Airport extreme "knows enough" to send the expected response back down to your computer. This magic all happens automatically for things like your email, web, ftp, etc.etc... because these services all follow a "back-and-forth" communication model.
The problem with protocols like BitTorrent (or running your OWN webserver for example) means that, you never know who is going to come knocking. It's not that the Airport is denying these "visitors" so much as, it wasn't told that anyone was coming.
To fix the problem you need to tell the Aiport extreme to roll out the welcome mat, and also... you need to the the Airport *where to send these visitors* That is what you do with the NAT port maps. This is how you tell the airport, when somebody comes and knocks on this door, send them to my PC. (Not, my laptop, or my iPhone, or my printer, or anything else that may be on the network: send them to my PC) After all, it is the PC that would be running BitTorrent, or Unreal, or a webserver, or ICQ, or what-have-you...
So now all you have to do is find out the IP of the machine you want to send the traffic to, and then you need to find out what PORTS that traffic arrives on.
For example... if you wanted to run a webserver on your home machine at internal ip: 10.10.10.2; then you would tell the Airport to route all incoming traffic on port 80 (the HTTP port) to internal address 10.10.10.2 (your PC). And that's it.
It has been my experience that BitTorrent uses the following ports:
tcp 13405
udp 13405
tcp 6881-6999
udp 6881-6999
TCP and UDP are two different flavors of internet traffic, and there is a section in the NAT redirections that allow for each... make sure you place them in the proper places.
Hope that helps. If it doesn't, let me know and I'll email you a screenshot of what the config page should look like.
I had already set things up this way ... and it does work, sort of. But I find that in some cases a mere 25% of my attempts to communicate out/back succeed. So I would love to take you up on the offer to send screenshots. Thank you so much for all the help!

Need expert cable modem airport extreme advice

I have been on hold with Comcast for an hour and so far no end in site. So I thought maybe someone here might be able to help me.
Because of Comcast's recent decision to cap bandwidth to 250GB a month I moved up to their Business Class high speed internet service that have NO bandwidth cap. I also get 16MB Down and 2MB Up for just $20 a month more, but the no limit on bandwidth sold me.
Anyway, they installed the new modem today while I was away, and when I returned home I saw that my Airport Utility was reporting a "Double NAT" error. Airport recommended changing the unit to "Bridge mode" (I also have two other base stations in the house), which corrected the Amber light, Double NAT error, but while I can connect to the net I am getting slower speeds.
Speakeasy.net is showing me that IF I use Bridge Mode I will average 8-10MB Down, and 1-1.5MB Up, but if I allow the Double NAT error by using "sharing a single IP" address I get an average of 15-20MB Down and 2-2.5MB Up.
Bridge Mode doesn't affect the other two units on my network, and while 8-10MB Down is still quite fast, the 15-20MB is a quite a bit faster.
So my question is this: Does the Business Class modem serve its own DHCP/NAT and if I set my Airport to "Share a single IP" it is redundant? Are both the cable modem and the Airport attempting to use DHCP/NAT and that is what causes the error? Lastly, is there a real reason for using Bridge Mode instead of "share a single IP", with respect to security, stability, or anything else? Does it really matter which one I use as long as I am able to use the net on my computers?
Thanks in advance for any insight you can provide. And yes, I am STILL on hold

Installing ATT modem & Airport Extreme

I just subscribed to ATT DSL and only have instructions to connect phone line, modem and computer. ATT won't give tech support unless you have their wireless Gateway. Can someone tell me how I connect what cables to what/where to the modem, computer and Airport Extreme. As you can tell I am not savvy to all this tech stuff.
Thanks for our help.

Download Apple's Designing Airport Networks document. Page 24 has a prettier picture than I can draw.
Disconnect and power down your DSL modem. Then, connect all the cables, turn everything "on" and run Airport Utility if necessary to ensure everything's configured properly.

Apple usb modem & Airport Extreme

Does the external Apple usb modem work with the AirPort Extreme (802.11n)? Has anyone tried this?
I use dial-up internet service and was wondering if the AirPort Extreme can use an Apple usb modem to connect to the internet. Thanks.

The USB port on the 802.11n AirPort Extreme Base Station (AEBSn) is only for connecting USB hard/flash drives, printers, or hubs. The USB modem will not work.

AirPort Extreme as modem

Hello!
I was wondering if the AirPort Extreme can be used to communicate wirelessly with my MacBook Pro and via hardwire ethernet with my Mac Mini.

Hi Brian
The Airport Extreme has both a LAN and WAN port in th eback, so yes you can hardwire it to your Mac Mini and use the MBP wirelessly.
Your need to have an Ethernet modem (cable or dsl) between your dsl connection and the Extreme for DSL access.
Internet--Modem--Airport Extreme--(Mac Mini - Wired) & --(MacBookPro - Wireless)
Of course you can use the internal modem as well, but then you are restricted to dial up speeds.

Trying to set up airport extreme with a dsl modem and get DSN server not found message . Get a green light on airport but no internet modem and get

Am attempting to set up a Wi Fi network with an airport extreme. Get most of the way through the setup (have a dsl modem) but get an error that it cannot connect to the internet. Says I have a problem with a DSN server and asks for what appears to be a series of numbers. I had an old airport express working for some time and never saw this.
Decided to upgrade since the express was not powerful enough to work in the whole house.

It is always a good idea when changing out networking hardware to perform a complete power recycle of all of your networking gear.
Please try the following:
Power-down the modem, AirPort Extreme Base Station (AEBS), and computer(s). Leave them powered-off for at least 10-15 minutes.
Power-up the modem; wait at least 10-15 minutes to make sure that is has enough time to initialize.
Power-up (plug into power) the AEBS; wait at least 5-10 minutes or until its status light is a solid green. (Note: The status light may continue to flash amber after this timeframe. This is ok as it may just be letting you know that some additional configuration items need to be taken care of like setting up wireless security.)
Power-up the computer(s).
Computers connected to the AEBS by either wire or wireless should now be able to access the Internet. Please post back your results.

Disconnect Airport Extreme PPPoE Connection

Hello!
I'm using the current configuration:
DSL Link -> SpeedStream ADLS modem -> Airport Extreme -> Computers
My Airport Extreme is configured to establish the PPPoE connection (the modem is bridged).
However I don't find an option to disconnect the PPPoE of the airport if I wish to.
The given options are:
-Always on (dials and stays connected forever)
-Automatic (dials on demand, and disconnect if idle)
-Manual (does nothing...)
I though this Manual option should have some sort of Connect/Disconnect Button or menu option, but I can find nowhere... Oddly enough, if this option is set, the AEBS doesn't connect and I never get an IP...
My question is: how do I manually connect/disconnect my PPPoE connection?
It can also be an Applescript funcion, whatever works...
thanks!!
PS: I tried to bridge the AEBS and relay the PPPoE to Mac OSX 10.5.4... but it can't find the PPPoE server in this case.
PS2: Mac OSX 10.4 had an Utility called Internet Connection, which supposedly had an option to disconnect the airport... but 10.5 removed this app.

One last try...
Configure a computer located near the DSL modem to connect wirelessly to your network and by Ethernet cable to a switch sitting between the DSL modem and the router. Remotely control this computer and use it to change the configuration in the DSL modem when you want to disconnect or reconnect your network from the Internet without restarting the router.

Connect to internet via airport extreme via ethernet cable and no airport c

I just bought a MacBook with Airport Extreme, got it set up today and it works great, got online, etc. However, I have an iMac with no airport card. I can't figure out how to get both computers hooked up on the internet at the same time. The MacBook works only when the ethernet cable in in the LAN slot on the Extreme but won't work through the WAN slot. I have tried hooking up both ethernet cables into the Extreme, just the iMac, and nothing works. I don't need to connect wirelessly through the iMac so I don't want to buy an Airport card if I don't need one. I just don't want to plug and unplug the ethernet cable everytime I want to use the MacBook or the iMac. My modem from Verizon only has one ethernet slot. Any ideas?

You mean Airport Extreme Base station?
Here's what you need to do:
1. Disconnect your Verizon Modem & Airport Extreme
2. Connect the ethernet cable from the Verizon modem to the WAN of the AE
3. Connect another ethernet cable from the LAN port of the AE to your iMac
4. Turn on Verizon Modem
5. Once all lights on the modem have turned on, turn on the Airport Extreme
6. On your iMac click on Applications --> Utilities --> Airport Admin Utility
7. Setup a Wireless network using this or the Airport Setup Assistant, located in the same Utility folder.
8. After you have created the wireless network, connect to it on your macbook
If for some strange reason you still can't figure it out, refer to the product manual or check:

Airport Extreme Slowing Internet Connection

Hope someone can provide some direction for me!
A few weeks ago I started noticing slowed internet speeds,but thought nothing of it, and attributed the slow down to peak periods. About a week ago was the first time I ran a speed test due to a noticeable depreciation in connection speed. Then, and still today, I’m averaging about 3.4 mbps down / 6 mbps up both wireless and wired with Ethernet cable through the airport extreme. I have Comcast Blast which, until the slowdown, was averaging 20 mbps down / 6 mbps up.
My setup:
Macbook (mid-2010), OS X 10.7
Mac mini (early-2009), OS X 10.7
Motorola SB5100 Modem
Airport Extreme 802.11n (3rd Generation)
Here’s the kicker: when my macbook is directly connected tothe modem (removing the airport extreme), I get amazingly fast internet (26mbps down / 6 mbps up).
I’ve been browsing around here looking for solutions since my warranty’s expired and have tried the following:
thanks to this previous discussion
-Changed Frequency Channel to less populated channels
-Changed Fireware Versions (was 7.5.2, tried 7.4.2, 7.4.1,and 7.4)
-Moved the router’s location
-Moved the
-Reset the modem
-Reset the Airport Extreme
-Factory reset the Airport Extreme
-Made sure “Ethernet WAN Port” was set to “Automatic(Default)”
-Changed/Temporarily Removed Security
Some users have found success (as discussed in the discussion linked above) by swapping out their cable modem. I own mine, so it would be a matter of purchasing a new one (though I'd rather not buy a new one if it's actually my Airport that's failing)
Could my Airport Extreme be dying and it’s time for a new one?
Any suggestions or thoughts of things to try?
Thanks, Everybody!

Well, I'll see if you can explain this one:
As suggested, I used Airport Utility to switch the Radio Mode from "Automatic" to "802.11a/n - 802b/g." I was unable to find the option to select "802.11n (5) only - 802.11n only (2.4)."
I ran the test again with the following results:
     Client Side: [ 4] 0.0-60.0 sec 497408 KBytes 67909 Kbits/sec
     Server Side: 0.0-59.7 sec 497408 KBytes 68253 Kbits/sec
No Change.
I then discovered that under "Wireless Network Options..." my checked "5GHz Network" had become unchecked. I re-checked this box and connected both server and client computers to this new network and re-ran the test:
     Client: [ 4] 0.0-60.1 sec 392192 KBytes 53496 Kbits/sec
     Server: 0.0-60.1 sec 392192 KBytes 53476 Kbits/sec
Seemingly slower.
HOWEVER, now when I run an internet speed test, I'm consistently getting ~28mbps down/~6mbps up across all devices (mac mini, macbook). I'm sort of unclear as to what's causing this change, but it appears, at least for the time being, that the issue has resolved.
Should I be concerned that the AEBSn is not transfering data near the 300 Mbps on the 5GHz channel? What else could be playing into this issue?

New Airport Extreme not working with my Quad Macpro

Hi all-
My Linksys 902.11b router finally died and our household is now completely Mac-based (all with Airport Extreme cards), so I decided to take the plunge and get an Airport Extreme.
2 of the machines on my home's network are doing fine with the router and are getting good speeds - iMac Dual 2.4 (10.5.1) - Both the wired and wireless connections are solid with this machine / Macbook Dual 2.0 (10.5.1) - Both the wired and wireless connections are solid with this machine as well.
I have a Macpro Quad 2.66 machine running 10.4.11. I cannot upgrade to 10.5 yet on this machine since it's being used in my recording studio business and there are known issues with some of my apps and 10.5 at the moment.
The Quad can see the network and has seemingly strong signal from the Airport Extreme BS, but DHCP reception is inconsistent (the machine often eds up using a self-assigned IP for some reason) and IP connectivity in general is inconsistent, even when an appropriate static LAN IP is manually setup. I can often get to a few webpages while using a manually config'd IP, but only with very slow DL speeds and then the connection quickly disappears and drops out entirely.
The AExtreme is setup like this: DSL Modem-->Airport Extreme (config'd with a static IP from my ISP) -->DHCP broadcast dummy IP's to my network. Currently I've not setup any security since I'm in the process of troubleshooting and I don't want to further complicate the situation. Radio-mode on the AExtreme is set to 802.11n (b/g compatible)/Channel 1. I've tried numerous config setups on the AExtreme, but none have helped the situation.
I've also disabled IPv6 on all clients per some reading on the forums of possible issues.
Anyone know what the problem might be? Is it perhaps an issue because the Macpro's using 10.4.11?
FYI, I've also also got an extra Airport Express around that's not being used that could be used as a repeater/wired connection downstairs if broadcast strength is the issue, which seems somewhat unlikely to me. I'm not sure how to config the AExpress to work in this capacity though, so if anyone could point me to a tutorial I'd appreciate it very much.
Thanks in advance.
Lee

I just did some more testing using an app mentioned here on the forums, iStumbler. The app offered these details:
- Signal Strength is between 45%-56%
- Noise is between 24%-41%
- Freq = 2412
- No websites load despite it's seeing the router and saying we've joined it.
I also did a screen capture of the iStumbler's screen in case that's helpful. There were several bits of info I wasn't sure about.
Here's the screen grab: http://www.pbase.com/infiniteposse/image/91793322/original
