AT&T U Verse

Welcome to the discussions!

Can you clarify if "AT&T DSL" implies that you are now using a simple modem with a single ethernet port that is connected to your AirPort Extreme, or does this imply that you are already using a wireless router with 3-4 ethernet ports?

Is this a dual band AirPort Extreme that you have now?

Thanks for the info.

You will have no problems if you connect an ethernet cable from the WAN port (circle icon) on your AirPort Extreme to one of the LAN <-> ports on the Uverse router.

All settings on your AirPort Extreme can remain the same except that the Extreme must be setup in "bridge mode" since there will be another router (the Uverse) ahead of it.

Your Uverse router will also create a wireless network, so you will have two wireless networks, if you wish. You might want to turn off the Uverse network if you don't need another network, or use it as a guest network, etc.

I am in the same position--switching over to U-Verse in a couple of weeks. The answer that was posted was precisely what I have seen elsewhere, so thanks. One more question though--I currently also have an Airport Express to push music to a home theater, which is using the Extreme as the core router. Are there any issues with using both the Extreme and Express in this setup if the Extreme is set to Bridge mode?

No issues at all. There should be no further configuration required other than setting the Extreme up as a "bridge" so that it will work correctly with the Uverse router.

Thanks Bob. I may hit you up if I run into any gremlins once I start the cutover--if you don't mind. Cheers.

Hey Bob,
Good news to report. Got U-Verse on Monday, and set up the AE in bridge mode. Actually set the 2Wire to address everything on the 10.0.0.x subnet, and got the AE to talk to all devices, including my Airport Express. Everything is working well with the exception of one hiccup--my MacBook Pro has had an IP conflict twice in the last three days, where it appears that either the 2Wire or AE is trying to give the same address out more than once. Not a huge deal, as the MacBook just gets another address with a DHCP refresh, but definitely odd. Obviously, both the 2Wire and the AE are currently doing DHCP (wired TVs and the AE for the 2Wire, and computers and iPhones for the AE), but I figured that they could do this simultaneously without stepping on each other. Any thoughts?

Other than that, thanks again for the instructions.

Glad things are generally working OK.

If you have the AirPort Extreme configured as a "bridge", it is not doing DHCP at all. The U-verse router is taking care of this.

Interesting. So the 2Wire is providing addresses to my computer and iPhones, even though they are connecting wirelessly to the AE. Makes sense, although then the fault lies with the 2Wire for letting addresses conflict. Thanks for the info.

Would be a good idea to do a power cycle on the network. Power everything down...order is not important.

Start the 2Wire first and let it run a few minutes, then start the Extreme for a few minutes, then your devices one by one.

Will give that a shot. Like I said, it's not causing significant problems, but still like to find the root cause.

Cheers

ive noticed a lot of these questions about at&t dsl and uverse involve setting up the airport extreme / or wireless router in bridge mode. and then having to work around double NAT.

the solution i do not see being used a lot is to simply put the at&t modem in dumb mode or dmz mode, and let the airport or other wireless router take over all of the routing, fowarding, login, etc.

for uverse this method might work better then going through the hassle of double nat

the 2wire modem (2700hg-b) on at&t dsl can also be put into dumb mode to allow
airport extremes take over the routing also.
you can either setup dmz zone to the airport in the 2wire configuration page
or try some of these activation keys.
522P-22P4-6262-22AT-F2NV for ppoe
522P-22P4-2E62-22AT-F27W for static ip (i have static so this is the one i use)
522P-22P4-2262-22AT-F2L3 for dhcp
522P-22P4-A222-22AT-F24N point to point over ATM

i forget exactly how i did it in my situation, but i turned my 2wire into a dumb modem. i don't know if this works for uverse, .. so my airport xtreme is responsible for all the routing, login (if i was using ppoe) and all that other stuff. i am not using double nat

im not sure if you can do with uverse, i dont have uverse, i do not know if the tv is going through that 2wire box...

but with dsl once u put the 2wire box into dumb/modem only mode, your pretty much stuck with it, and you have to push the reset button on the modem with a paperclip if you ever want to return normal functionality to the unit

Bob,

Your comments have been very helpful. I have the Airport Extreme working (with AT&T U-verse and a 2wire router, with the wireless turned off). But now I'm trying to add the Airport Express (to extend the signal to the far end of the house), and that isn't working at all. If I try to set the Express up in bridge mode, it wants to be connected by Ethernet. But if I try to join the network (which is working fine for several computers and a printer) the Airport Utility can't recognize the Express after the settings are updated.

Do you, or does anyone, have an idea on how to set up the Airport Express in this situation?

Thanks,

David
