I have a Dell 8100, Win XP Pro and 3com 3c920 NIC.

My DSL is working properly, however, if I connect my LinkSys EtherFast DSL Router (BEFSR41) I cannot connect to the internet and the NIC has RED light.

I replace the router already thinking that it might be defective, still I got same result.

I appreciate all help. Thanks.

I had a similar problem with my connection. My ISP would only allow connections using the modem they supplied...I had to use their modem and then attach my router to that...

The next things I would check are:

1. What speed and duplex does the router connect at and what speed/duplex is the port on the modem?

2. Do you need to configure the router with a specific IP address supplied by the ISP?

3. When you go to a DOS prompt on the workstation and type IPCONFIG what IP address does your workstation have? If XP isn't configed with a static IP address and doesn't see a DHCP server, it will auto configure with an invalid IP address.

4. Also, what speed/duplex is the NIC set at on your workstation? Does it match the port that it is plugged into on the router?

If you have configured your router to PPPOe and cannot connect. You might have to change the LAN address on the router to 192.168.254.1.

I have also seen where the router is not allowed to make the connection since the modem is already connected. You have to put it on obtain IP automatically. then release\renew ip. shutdown the computer, the router, then modem, then restart modem, the router, then computer.

Some people swear by linksys... I for one am on of the haters... Went through 5 routers of theirs with the same issue you have.

The solution is to download the latest "firmware" from linksys and zap that router. There are 3 different ways of doing this - some will fail...

I have since switched over to D-link as a more reliable product.

I still have 2 of the 5 that wouldn't hold the new firware resulting in the "Red Light of Death" just for my collection of junk to remind me what not to buy.

You can send it back to linksys and they will replace it if the firware updates do not take. But as I said, this is a common problem with their hardware.

Does your ISP require a PPPOE connection? I've recently run into a couple of setups where the isp sends out the dsl modem/router with the cd software that you have to load on your pc. Basically, that software establishes the PPPOE connection for you and gives you a bunch of useless icons down in your toolbar. By default, Linksys routers do not have PPPOE setup. You might want to try using your isp supplied username and password and trying PPPOE on the router. What kind of dsl modem/router are you using? Was it a do-it-yourself kit or did someone install it for you?
