Please log in for more thread options Just got married and moved in with my wife, who has Comcast cable broadband. (Had previously been on Verizon DSL.) She has a Motorola SB1500 SURFboard cable modem and a LINKSYS BEFSR41 router; runs Windows XP Home. (Pretty sure it's SP2.) Looking at the quick setup guide for the router, I tried plugging my Windows XP Home SP2 box in. Didn't work. Tried a few things, then finally got it to work when I found that I can get one computer (but not both) running broadband. Pattern seems to be that the one I plug into port 1 (or whatever it's called) on the router works, but not the other. Any suggestions on how I can get both to work simultaneously? I did some web/USENET searches on this, and can't quite figure it out. (I went to the admin web page for the router, and it says it's set up for 50 PCs, not merely 1.) TIA, S | ||||||||||||||||

The cable modem should be plugged into the "WAN" port and port 1 is connected internally, but with reversed directional sense, to the "Uplink" port If the router has DHCP enabled, you should configure your computers to seek a DHCP IP assignment from IP address 192.168.1.1. If DHCP is not enabled, manually assign the computers IP addresses in the range 192.168.1.[1..254] You should also specify the router's address (192.168.1.1) as the DNS server. -- Tom Stiller PGP fingerprint = 5108 DDB2 9761 EDE5 E7E3 7BDA 71ED 6496 99C0 C7CF | ||||||||||||||||

>A couple of things. The cable modem should be plugged into the "WAN" >port and port 1 is connected internally, but with reversed directional >sense, to the "Uplink" port I don't think the BEFSR41 has that relationship between Port 1 and the WAN (Internet) port, and there is no "Uplink" port. Some older equipment was like that, though. >If the router has DHCP enabled, you should configure your computers to

your example for the computers should be 192.168.1.[2..254].
