Hey guys,

so over the past 2 weeks i cancelled a previous dsl subscription and i am now with AT&T

my activation date was today and i wasnt able to connect to the net with my new modem... after chatting with tech suppport they made me login to the modems IP address to configure an email setting which somehow solved my issue

i can browse the net perfectly when my macbook is directly connected to the modem with the ethernet cable but when i try to connect the ethernet cable to my linksys wireless router (which worked perfectly fine with the last modem ..) i cant seem to browse the net

is there some kind of IP config that i have to do? i successfully logged on to the linksys wireless router's ip address and i can also see that connection is at full capacity in the airport connection icon on the top of my window...but when i try to surf the net using the wireless conneciton it kind of just stands still and the page doesnt load


can anyone give me some help pls? thakns

Ok what brand and model is the new modem? Also need info on Router. I think I know what is going on but need that info to help you.


Some modems AT&T (SBC) ships have a one IP address router built in and will not work unless you change a setting. Just dealt with one of them a month ago.

Agreed with dtravis.

An even simpler thing to try would be to make sure that you have powered off the router and powered it back on and wait for 30 seconds after you attach the modem to it.

More often when this type of situation occurs, it's because the modem has a router that is using the same default IP address as your router (usually 192.168.1.1 or .100). Sometimes you just need to change the IP range and assign the router something in a different subnet. I like to use 192.168.0.1.

Try this:

- Start with the computer turned off
- Unplug the power to the DSL modem and the router
- Plug the DSL modem in and wait 30 seconds
- Plug the router in and wait 30 seconds
- Start the computer and attempt to connect. If this works, great, if not...

- Open a web browser
- Type the address of the router into the address bar. I believe it should be 192.168.1.1 or 192.168.1.100. Try both, when you get prompted for a username and password, you know you have the right one. The username should either be blank or admin. You should have set the password when you initially configured the router. If you don't remember it, we'll need to do a cold reset on the router.
- Once you get into the configuration page, you'll see a field for "Local IP Address". If it's 192.168.1.1, change it to 192.168.0.1. If it's 192.168.1.100, change it to 192.168.1.10.
- Click "Save Settings" and close your browser. You should be able to get to the Internet now.

ok i changed it from 192.168.1.1. to 192.168.01.1 and the settings were saved and it said renew/reset ip or whatever ..it cut me of from the connection (as indicated in my airport icon) and then i manually connected again using my password and all 4 bars of the airport became bold showing that i was connected

however i still cant browse the net using the method u listed above? is there anything else i need to change in my setup? above the local ip adress it says that im under "automatic config DHCP"

Did you really use 192.168.01.1 or 192.168.0.1?

I wish I would have heard from you last evening, when I was home in front of my WRT54G

It sounds like you changed the correct setting. And yes, unless your ISP uses static IP, it should be set as DHCP/automatic configuration. If they did use static IP, they would have supplied you with a set of parameters to use to configure your PC.

If you haven't already done so, shutdown the Mac. Power cycle the modem first and then power cycle the router. Then, boot up the Mac and see what happens. If that doesn't work, I'll have to take a look at my WRT54G this evening to give you some more instruction.

I just talked to a very smart DSL tech that came here to fix my DSL. Smart and cute also! Female.

Anyway, sorry I did not get back to you sooner as I was without internet except dialup for 2 days now.

I confirmed with her that that Motorola Modem you have there does have a simple router. You change it to bridged mode in the config and let your Linksys handle the connect to PPPoE. I have had to do that with the 5100 and 5100B Speedstreams I have worked with but was not sure on that Motorola. I will try and find a manual later and tell you what to do. So nice to have DSL again!!

My issue was their end like I tried to tell Level 1 support but all said it was my Mac, Router, Modem, Wiring. Funny, as I told them all was fine. I was plugged into an overloaded router at the CO! hahaha.

It is possible to have the two routers coexist if you so choose (which is the tack I usually take). But if you want to walk him through switching the modem over to bridged mode and set the router to do PPPoE/authentication, I'll shut up now

Naw, do not shut up!

I have to go shopping. My whole day was wasted having to wait for the tech but glad I did as it got solved.

Which ever works and gets the OP up and running is all I care about. Those Speedstream 5100b's are so easy to switch to bridged mode I usually just do it as it takes me 30 seconds.

OK, I'm used to seeing the Westells which Verizon seems to use in this neck of the woods - they can be a pain to get working in bridged mode, plus I don't have one available here for reference.

So far, my method doesn't seem to be working anyway
