The firmware on these particular line of linksys routers is really terrible, I suggest upgrading to a third party firmware. There are also severe p2p problems that can be scripted with new firmware. Depending on which version of firmware you already have you may need to first upgrade to the newest version of linksys firmware before installing the dd-wrt firmware. I went through his process last week, and couldn't be happier with my routers improved functionality. Make sure you follow the instructions for your particular version of the router (you can figure this out by the serial number) and follow them precisely or you risk bricking your router. Here are the links you need to get started: Firmware Site Wiki Detailed Tutorial
This very well may not solve your problem, but if you research this router you will find loads of issues this firmware solves, not to mention the ability to insert scripts to enhance the routers capabilities and customization. Good Luck!!!!

Well you'r ISP connection is good since you have internet when connected to the modem (just be verry prudent since you have no security when connected to the modem)
First verify with you'r ISP what type of connection you have (STATIC IP, DYNAMIC IP/DHCP, PPPOE, etc...) Ask you'r ISP if they can reset you'r account (MAC ADDRESS, PASSWORD, etc...) You can also verify the connections from the modem to the router (CABLES, CONNECTORS, etc...)
Different ISPs require different configurations. If you have a Linksys router, such as the WRT54G, there are 2 ways on how you can configure it, either by running the Setup CD or by doing manual configuration. This particular router has its own web utility and you can access it by typing its IP addres on your web browser, ex. http://192.168.1.1. By default, it doesn’t have any username and its password is admin.
Once you’re inside the setup page, you can configure now the router for DHCP, PPPoE or STATIC IP settings. For DSL customers using a PPPoE account, some modem needs to be configured into BRIDGE MODE first and then the router will be set to PPPoE with the correct username and password (given by ISP). If your a DHCP account, modem doesn’t require any configuration. It will work with its default setting and the router would be set to DHCP. Once done, powercycle your devices to establish internet connection.
I've tried: Having the router get an IP automatically from the modem. Changing the router's IP address. Having the modem pass PPPoE authentication to the router. Bridging the modem. Power cycling the guts out of everything.
Most residential subscriber services use dynamic IP addressing. Dynamic IP addressing is automatic from your Internet Service Provider (ISP). Linksys home based products such as the one you have should be setup up for this configuration out of the box by default, and require no adjustments to the IP configuration of the wireless router. You should power down the DSL modem and Linksys, then connect them, then reapply power. This will clear the DSL modem if it was connected to another device such as a PC. This is important as most cable and DSL modems use something called MAC address binding that will only allow one device to connect to it directly at a time.
You need to reinstall the router to your modem. Start with unplugging both the modem and the router. Plug in the modem and wait for der blinkin' lights to stop (linked to host) then plug in the Linksys. Now, depending on whether you have a DSL or Cable Modem, you need to follow the installation instructions. In DSL, you will need to set PPPoE, a username and password, etc. You can go to the Linksys site and get the FAQ for your modem here http://www.linksysbycisco.com/US/en/support/WRT54G
If the setup does not work, and most notably in Cable Company modems, they may have to send a reset to make the Linksys work.
does your ISP use DHCP or PPPOE and what is the LAN IP address of their MODEM ,,, now IF they use DHCP and Lan ip is anything other than 192.168.1.1 then in back of linksys press reset button in back of linksys and hold it down (with power on to linksys) for 20 seconds then wait for 2 min and turn linksys off (unplug pwr cord) and your modem off for 3 to 5 min. turn your modem on first and wait for your dsl light and wait 2 min then turn pwr on to linksys (plug pwr back in) and wait another 2 min. IF ISP is PPPOE or if their mdm has same lan ip have your ISP bridge mdm if they have dhcp you won't have to do any thing else but pwr cyc as i said above if they use pppoe then have linksys on and type 192.168.1.1 in address bar and type "admin" in for password only (if that don't work use it for both then where it say internet connection type set it for pppoe and type in your email address and password in the username and password field and save and pwr cyc mdm and router again
Basic DSL Setup - PPPoE Most Internet Service Providers offer PPPoE authentication. Please consult your ISP if you are not sure if PPPoE could be used.
To configure your router for PPPoE you will need to set your router's WAN (INTERNET) port to 'PPPoE' option. However majority of Modems nowadays already have PPPoE enabled. If your modem has PPPoE client built-in, you need to select the 'DHCP' option in your router. The router is set to this option by default.
Step 1 Connect the broadband modem to the WAN (INTERNET) port of your router. If the modem has USB connection make sure that it is NOT connected to any computers via the USB cable and that the modem is switched to Ethernet (not USB). Only the modem's Ethernet port should be connected to the router's WAN (INTERNET) port. Connect your computer(s) to the router's LAN port(s) or establish connection to it wirelessly.
Step 2 Open your Internet Explorer and log into your router by typing in its IP address (in most cases the default IP is http://192.168.1.1 ). Note that you do not have to be on the Internet in order to access this address because you are just connecting to your router's address. Specify username and password for your router, the default password is `admin' (optional) and username is blank (nothing).
Step 3 After logging into the router select Setup. Set Internet Connection to 'PPPoE' option. This can be done by either clicking on Internet Connection Setup Wizard or if you want to set it up manually, then click on 'Manual Internet Connection Setup'. Note that it is very common for broadband modems to carry out the PPPoE authentication for you. In this case you need to select the 'Dynamic IP' option (DHCP) in your router, do not select PPPoE. If you have such modem proceed to Step 5
Step 4 If your broadband modem does not have PPPoE function, select the 'PPPoE' option in the router and enter your account details (username and password given by your ISP). Note that some ISP's require username to be as your full e-mail address (ex: firstname.lastname@example.org).
Step 5 Click on SAVE SETTINGS and then on REBOOT THE DEVICE to apply the new configuration. Recycle power to modem.
You do not have to run any login client (like PPPoE) on your computer in order to connect to the Internet. If you had it setup when using the modem without the router, disable it in Internet Explorer under Tools > Internet Options > Connections > set to 'Never dial a connection'.
If you did not have to run PPPoE login client on your computer when modem was directly connected to your PC, your ADSL modem has PPPoE built-in. In this case set the router's WAN (INTERNET) port should be set to the 'Dynamic IP' option.
If your ISP requires PPPoA connection you need to make sure that your ADSL modem supports PPPoA (PPPoA can not be used on Routers which do not have ADSL Modem built-in). If your modem will be carrying out PPPoA connection you need to set your router's WAN (INTERNET) port to the 'DHCP' option.
If you are having difficulties accessing the Internet:
- Turn the modem and the router off for a minute and then turn the modem first and then the router.
- Log into the router and go to Status page. Note what IP address it is getting on the WAN (INTERNET) interface. If the IP address you see under WAN (INTERNET) appears to be in the same range you are using on your network (e.g. 192.168.1.x), you will need to change the range you are using on your LAN to something different, e.g. 192.168.88.x. You can do this on your router under Setup > LAN Setup. Note that after changing the IP of your router you will only be able to access it through its new IP, e.g. 192.168.88.1.
- Select the MAC Cloning option. Click on Clone MAC Address button. Do this from the computer which the broadband modem was directly connected to the last time. This will place the MAC address of your computer into the router. Save settings and reboot the router. Reboot your broadband modem as well.
- Uninstall your antivirus software (sometimes disabling or closing the software is not enough) and reboot your PC.
Connect your computer to one of the LAN port of the router, access the IP address of the router (IP 192.168.1.1), for the connection type choose PPPoE, type the username and password provided, Check the IP address under status (WAN section if the IP address is 0.0.0.0 then click connect)
I have att yahoo dsl which I installed about a year ago. The process required bridging the ADSL Modem (in my case a speedstream 4100) and accepting dynamic IP addresses and configuring PPPoE on the WAN side of my Linksys router. The ATT support person walked me through the entire process over the phone even though I was comfortable with making the Linksys configuration changes as I had to do the same in China without technical support. The modem configuration was no more difficult than the router configuration as it was performed from a web browser too. The biggest warning was that to reverse the modem change (if desired) required use of a reset button because the web interface was disabled as a result of the configuration change. My advice to you especially if you are willing to attach the Linksys router to the telco modem is to contact the ATT highspeed DSL support line and see if they will walk you through it like they walked me through it. Reviewing your Linksys User's Guide and understanding the configuration of that device would probably be appreciated by the ATT Support person as well as assuring you can access the Linksys router to configure it during the call.
