Trying to resolve a DHCP conflict involving Airport Extreme

I have my LAN set up so that the router hands out addresses with DHCP in the 192.168.1 range. Also on the network is an Airport Extreme (an older 11g model running the 5.7 firmware). I am having a terrible time trying to configure it so that it hands out addresses to its clients in the 10.0.1 range. No matter what I try, the Airport DHCP server is overridden by the DHCP server on the main router and a 192.168 address is assigned.
On the first configuration page of Airport Utility under the Internet tab, I have chosen Connect using Ethernet and DHCP. And I have chosen "Share a public IP address." Under the DHCP tab I've indicated beginning and ending IP addresses from 10.0.1.10 to 10.0.1.20. Why then when I connect to the airport with, say, my laptop, do I get a 192.168 address?
Any advice would be much appreciated.

What you are trying to do is quite common, but perhaps the key is that the LAN with the DHCP router assigning 192.168.1 addresses must be connected to the AEBS via its WAN port.
In a default (configured from Factory Reset) scenario, the AEBS will request an IP address from the router via DHCP for itself, and will distribute IP addresses for its clients (wireless and via its LAN port) via DHCP from the pool you've specified if you have it set up to "Share a public IP address."
You can read more about setting up this type of network starting on page 24 of the Apple manual Designing AirPort Networks.
I suspect what's happening is the router is connected to your AirPort's LAN port, which causes a race condition between the two DHCP servers as to which will provide an address to new network devices.

I'm trying to extend the range of an Airport Extreme 802.11g by adding an Airport Express 802.11n. I set the Express up to join the existing network, but it does not make any difference in the range of the network. What's wrong?

Let me see if I can help you with the basic WDS configuration steps:
Note: To help facilitate the setup, temporarily connect the AXn directly to the AEBS LAN port using an Ethernet cable. Once the setup is complete, you can move the AXn to the desired location. For all configuration steps you will be using the AirPort Utility. Before starting, be sure to jot down the AppleIDs for both base stations.

The zillion and one setting to wade through might mean more choices to the tech-heads, but I just wanted it to work.
I don't recall the type of router we had at my previous job, but I just plugged it in, went through a simple set up and forgot about it because it just sat there and worked.
I have had to go back to factory settings and start from scratch with my Extreme many times. The last time the amber light started blinking I just ignored it for months, because it didn't effect my internet connection, I just lost the ability to get iTunes over to the Express I have hooked up to my stereo.
BTW, what's a wall wart?

Trying to connect Verizon wireless router to Airport Extreme but error says Ethernet unplugged.

Trying to connect Verizon wireless router to Airport Extreme and error says Ethernet Unplugged.

So, AirPort Utility running on the Windows Vista desktop can "see" the AirPort Extreme and displays its icon, but gives that error message at some point in the setup process? How far does it get?
Other questions that may help me (or somebody else) understand your problem better:
Which of the pieces were verified as working before the introduction of the AirPort Extreme?
Did you have the desktop computer attached to the Verizon GT704WGB with one of the Ethernet cables you are now trying to use? Which one? Have you tried the other one to be sure it also works?
Are you using the same port on the GT704WGB? Have you tried another one?
If the desktop has multiple ethernet ports, are you using the same one?
Had you done any special configuration of the ethernet port on the Verizon GT704WGB to get it to work with your desktop?
What category ethernet cable are you using? 3? 5? 5e? 6?

Trying to set up Directv GenieGO using Airport Extreme. Getting error message: DHCP range entered conflicts with the WAN IP Address of your base station. How do I resolve the conflict.

Trying to configure an Airport Extreme manually. After I enter the IP Address of the GenieGo along with the rest of information required I am getting the following error message when I click update:
DHCP range entered conflicts with the WAN IP address of your base station.
How do I resolve the conflict?

You cannot use the same range on LAN and WAN if you are routing.. it must be different.. and you should not be routing at all.
The AE should be in bridge mode. NO DHCP settings at all.

How do i use my own dhcp server with airport extreme

I just bought an airport extreme and I'm trying to replace my linksys router and another access point.
I have my own dhcp/dns server and I want to continue using it. So far, I was not able to find the way to use NAT without DHCP (like I'm doing now with my current setup).
I want to give the device another chance before I return it to the store. Is there anything I can do?
Thanks

I thought that you could figure out the answer for yourself, but if you need more confirmation.....the choices/options that you need do not exist on an AirPort router.
Cisco or Netgear might be brands to look at. Good luck in your quest.

I'm trying to decide between the time capsule & airport extreme. With either option, will i not have air play?

I'm trying to decide between the time capsule & airport extreme. With either option, will i not have air play? I have an IMAC, MACBOOK, 2 Apple TVs, 3 iPhones...

AIrplay to digital or analogue devices like speakers or hifi system is only available in Express. Or Apple TV.
The TC or Extreme will pass airplay protocol just fine to your ATV.
The Extreme and TC and now identical apart from the TC having an internal hard disk.

DHCP Passthrough on Airport Extreme

I have a small business network running a Windows SBS 2003 server that provides DHCP and DNS for the network. I'd like to connect the Airport Extreme and continuing having the server provide IPs, etc. to my wireless and wired clients. Do I simply put the Airport Extreme in "Connection Sharing: Off" mode and that should do it? I connect the rest of the wired network to the WAN port or one of the three LAN ports?
Thanks!

Ok, if I got you current network configuration correctly, it should look something like the following:
Netgear router > (Ethernet cable) > (Port_#A) Ethernet Switch (Ports_#B+) > (Ethernet cables) > wired devices including the SBS.
If your plan is to replace the Netgear router with the AEBSn, the problem is that you cannot disable DHCP without disabling NAT. If the AEBSn is configured as a bridge, another router will have to, at least, provide the NAT service.
Another option is to retain the Netgear router, but configure the AEBSn as a bridge (as you suggested), but connect the AEBSn to one of the ports of the switch. That way, the Belkin can continue to provide the NAT service and the SBS can provide the DHCP/DNS services.

Bridge Mode or DHCP for two Airport Extreme via ethernet?

I have Two airport extreme setup in a six floor brownstone home in New York City. My verizon internet router is set up on the top floor with an airport extreme, my basement has the second airport extreme connected via ethernet wired from the top floor. I use DHCP from verizon internet. Do I set up my two airport extreme Bridge mode or DHCP?
Im having issues with my iphone not connecting through my basement airport extreme. Airport extreme status looks fine, green light and in working order.
Please help.

Do I set up my two airport extreme Bridge mode or DHCP?
Bridge Mode. But, you don't have to worry about this, since the configuration wizard will do this for you automatically.

Will Time Capsule conflict with Airport Extreme?

I just purchased a Time Capsule but after reading the discussion board it looks like it might conflict or override my Airport Extreme? Also, if I do connect it, will it ever erase any information on its own without me manually deleting? I think I'm experiencing buyers remorse. My main purpose is to free up space on my iMac. I could have just purchased a simple external hard drive but this seemed like a better choice at the time. Help!

Depending on the age of the Mac a USB, Firewire or Thunderbolt drive would be a much better choice.. as an addition to the TC.. TC is still needed if you have no backup. If you store your files on the external drive think about where you want them to be backed up to.

No the TC and airport can live happily together.. just decide which is router and which is bridge.. as far as possible connect together with ethernet.. but you can wirelessly connect as well.
A TC is a backup device not really a NAS.. it has no means to back itself up.. but it will not erase anything without you deliberately erasing it..
Perhaps you mean the way Time Machine works.. if you erase something on the disk.. TM will eventually erase it from the backups.. this is very true.. but that is specific to TM and backups.. not to stuff you store on the TC. That is not erased unless you do it deliberately.
I think you should read over Pondini's FAQ to understand a bit more about TM and TC.
http://pondini.org/TM/FAQ.html
I learned a heap from them.. the home pages as well.
http://pondini.org/TM/Time_Capsule.html
Although TM is loaded on every Mac since Leopard.. and very convenient to use.. it isn't the only show in town.. and other utilities can do disk images and incremental backups.. without half the issues that TM does. Although more limited in restore potential as well.

Help! Im trying to extend the network on my Airport Extreme with an Express

This is probably such a begginers question but it has truely boggled my mind for the last 24 Hours!
I have brought an airport express to extend my airport extreme network. My Airport extreme is the base and is hooked up to my initial Home model from my ISP which works fine.
I have been trying to connect my airport express and am having no luck. I have plugged the airport in but am having no luck locating it on my airport utility (only my actual Airport Extreme shows)
Can someone please help me Ive been here for hours reading on forums trying to sort this out and Im gettin nowhere fast!
The light on the express is flashing orange. I have tried to reset it but there still is nothing showing.
any ideal on what i could do or follow step by step?

Ok, the question is how can i extend the range with
my airport extreme base,
With an Airport Express or another Airport Extreme
I have A netgear WNP802, it
has a repeating feature.
Which won't work with your Airport Extreme
< But i am wanting to have the
netgear and the apple airport extreme talk to each
other so that i can put the net gear in a seperate
room to extend the range of signal. </div>
This is not possible.
How can i do this?
You can't.
Netgear and Apple use different chips which means they won't and can't talk to each other when it comes to extending networks.

Maximum number of DHCP clients with Airport Extreme (802.11n)?

I see in the documentation that the number of wireless clients that the new Airport Extreme can handle is 50, but it doesn't indicate that it can handle more than 50 via the LAN ports.
Has anyone connected one of these units to a network with more than 50 simultaneously connected (wired) computers?
Thanks much.

Yeah, I knew I'd have to answer that question eventually. I debated including that information with my initial post--I should have. Sorry.
I realize that it's a home unit, and it will be when I'm done. I need to set something up as a temporary solution for a LAN party at our college, but I need to keep it separate from our regular network.
I've got all the switches I need (we usually get by with 3 unmanaged Cisco 24-port switches). I'm just looking for a solution that is simpler than reconfiguring a Linux machine as a DHCP server and gateway for a three-day LAN bash--I am more interested in the DHCP server functionality. So, has anyone seen one of the new units give out IP addresses to more than 50 clients?
Thanks,
Scott

Custom DHCP range on Airport Extreme?

Hi Guys,
I've been googling unsuccessfully for a solution to this problem. It seems that the Airport locks me into 3 possible DHCP ranges. However, I need a custom dhcp range like this:
192.150.23.*
Is there any hack I can use to do this?
Thanks!
John Francis

Um, someone correct me if I'm wrong but that's not an internal IP. In fact, It looks like Adobe owns that class C subnet.

Using DHCP Airport Extreme WRONG IP ADDY

I connect my modem directly to my computer and the internet works perfectly.
I try and use my Airport Extreme using DHCP and my Airport Extreme ALWAYS automatically picks an INVALID IP address.
I have no idea why the Airport Extreme is doing this.

When changing network configurations, it is always a good idea to do a complete power recycle of all of your network components.
Try the following, in order, checking for Internet access after each step, until resolved:
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, 802.11n AirPort Extreme Base Station (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."

Airport Extreme Network (Wired) Dropoffs

Hi everyone,
I've been suffering with a problem with my Airport Express for as long as I've owned it and finally decided I would make a major step to resolving the problem (primarily held back by not wanting to purchase another router to prove the problem).
I run a home Wireless network consisting of 2 x G4 PB 1.33 12" with Airport Extreme built in and 1 x Mac Mini with Airport Extreme built in. All devices connect to the Internet via this Airport Extreme which I have configured in NATing mode running DHCP. The Airport Extreme connects to the Internet (3Mbit/s Cable) via my Motorola Surfboard SB4100 Cablemodem using the Ethernet port. In between the cablemodem and the Airport Express is a 5 port 10/100 Switch, that enables me to connect my PS2/Xbox/GCN to the Internet (I have 2 Internet IPs, one for Gaming and one for Airport).
I have the Airport configured so that when there is activity the light flashes.
The problem I was getting was that occassionally (sometimes every 30 mins, sometimes more, sometimes less frequently but always frequently enough that I would be interrupted while doing things online) the connectivity to the Internet would pause. The pause was typically 10 seconds, sometimes less but never more than 20 seconds. While the Internet paused the light on the Airport would go orange and flash, as though it'd lost its IP address or something. Performing a hard reset on the device would not affect the reliability of the Airport and this connection and also up and downgrading the firmware from 6.1.0 to 6.1.1 to 6.2 does not affect the reliability either.
When I check the log of my surfboard occassionally I see sync'ing errors and put the problem down to this, however there were certainly less errors reported in the SB4100 log than there were downages.
I put the problem down to an IP renewal problem (where the Airport was renewing the DHCP lease) and kinda tried to tolerate the outages even though they are really annoying.
I had the opportunity to get my hands on a Cisco PIX 501 cheap the other day and took advantage in an effort to perhaps irradicate this problem or just perform some testing and my results are even more bizarre.
Now I have configured the PIX 501 to perform all the NAT/PAT functions that the Airport used to perform along with DHCP, etc.. The Airport has been configured purely as an Access Point, only bridging between wired and wireless.
The problem is still occurring in the new configuration!!
What I have found, though, from the indicator lights on Cisco PIX (indicating link speed and activity on the 4 ports of the integrated 10/100 switch) is that when the Airport goes "funny" the link light for the port that the Airport connects to goes out until the Airport goes back to green on its LED.
To me this looks like there could be an intermitted fault with the Ethernet interface on my Airport Express or a dodgey Ethernet cable. So I replace the Ethernet cable with a brand new 2m CAT5e cable to test this, and as expected the problem is still present. Next just to confirm absolutely 100% I move the Airport to a different port on the PIX and plug my PB directly into the old port (Disabling Airport) and test connectivity. I do not get a dropped link on that port and when the Airport is dropped I can still connect through the Cisco using my wired connection.
When I spoke to Apple they said that I should switch firmware versions to 6.1.1, then 6.1.0 and then back to 6.2 which has not helped either.
As a little quirky puzzler I can also force the problem to manifest itself by using Remote Desktop Protocol to connect to either a Windows Terminal Server or XP machine through the Airport. When I do this the problem will appear within minutes and recur every couple of minutes but not with any real regularity. Unfortunately for me this is something that I do very frequently
Before I try and take this unit back to Apple has anyone else seen this kind of problem and possibl

My apologies, perhaps it's not clear. The Cisco PIX is a router/firewall device. This is exactly what I have done and the problem is clearly nothing to do with anything except the Airport as my investigations and testing have proved.
