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

Are you using a straight through cable or a crossover cable ?
Did you try re-booting the PC ? It should pick right up on any
of the ports.

Straight.

I've cycled a number of times. Works on Port 1 but not 2-4.

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

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.

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.

Eek! <g> 192.168.1.1 is already in use by the router's LAN port, so
your example for the computers should be 192.168.1.[2..254].

Sorry to be nit picky, I'm just trying to avoid confusion.
