Make sure that your computer is able to go online directly through the modem.
If your computer is able to go online through the modem, that means the modem is working fine.

First!
Do you have a connection in your modem?
if you do, you need to set up the linksys router in DHCP internet set up.
To have access to the linksys you need to go to:
http://192.168.1.1
The password it's admin
and the username in blank (no password)
change the internet setup to DHCP

Make sure you don't have the Same address for 192.168.1.1 or you modem cause if you do you'll need to change the ip address on the linksys router...

Good day,
The AT&T modem(Motorola), is actually a modem and a single port router.
To work with the Linksys it must be set up in bridge mode. Then let the router make the decisions.
AT&T tech support will usually not help you if the router is not there product.
On Google, there are many sites that will help with this issue.
Unless you've already done it, you should contact AT&T by phone and request tech support on setting up your modem. They will talk you thru the whole setup, including testing but without the router.
Then proceed with the steps thru Google.
I do not know the settings for your specific router, but the forums will usually help.
I assume you're on DSL. Make sure they know that. Cable settings are different.

First of all you need to set you modem router to bridge mode. go to this link will explaine in more detail

remember to change the linksys router ip to 192.168.2.1 or 192.168.0.1 somthing different from the modem .
Hughes modems are all set to 192.168.0.1 so simply setting the linksys router to default 192.168.1.1
you need to change the linksys router IP to somthing different 192.168.0.1

Make sure that your computer is able to go online directly through the modem.
If your computer is able to go online through the modem, that means the modem is working fine.
You will need to connect the computer to the router and the modem to the router.

what is the model of your modem? if you said that you are able to get online when your computer is hooked up to the modem only, then it indicatest that your modem is not yet in bridge mode. Putting it in bridge mode will make your modem a "pass through" device thereby causing no conflicts in asking for ip add/connecting to your ISP. when your modem is in bridge mode, you should not be able to get online.
after setting your modem to bridge mode, connect your linksys router. if you have a pppoe connection, or one that uses username and password, have that set up in your linksys router. at this point, your router will be the one to ask ip adds from your ISP.

You probably will need to make some configuration changes in the Linksys router, or in your computer, or both. Your are correct that you connect the Linksys WAN connection to the LAN connection of the modem. If your connection type is PPPOE, you will need to set that up in the Linksys with the username and password provided by your ISP, so the modem will allow you to login and connect to the internet. If that is how you were connecting to the modem with your computer, you will need to configure a new LAN connection in the computer in order to connect to the Linksys. You can then configure the Linksys through your web browser to connect to the modem.
