Yes, both the Cat 5 cable is plugged in correctly.

ok...you don't have the ethernet cable plugged into the WAN port on the router do you?

what you should have is wire from the wall to the modem...cat5 from the modem to the WAN port of the router...then from the LAN port to the pc

[Zeljko]

That's exactly how it is. Cat5 from modem to WAN port, then Cat5 from LAN to Basement Computer Ethernet port, but the basement computer still refuses to acknowledge that anything is even pluggedinto the ethernet port.

hmmm....did either of those two ethernet cables come with the router? try switching them

[Zeljko]

I switched them, but that didn't work. The router didn't come with any ethernet cables.

[dsenette]

hmm...is it possible for you to move cmputer 2 (upstairs) down to the basement to see if you can get it to connect via ethernet?

[Zeljko]

Well I can't bring the upstairs computer downstairs right now, but what I have done is I have brought the router upstairs, plugged the router into the wall, and connected the router to computer 2. When I did this, the LAN light cam on on the router, and light at the back of computer 2 came on. Now, there isn't a modem upstairs, or any internet connection, but what this test indicates to me is that the problem lies with the basement computer, not the router. The LAN light never comes on when the LAN is connected to the basement computer for some reason.

[dsenette]

that's what i was wanting to check...hmm... since computer2 will be connecting wirelessly...is the ethernet card built into the motherboard or is it a pci card?

[Zeljko]

It's built in.

[dsenette]

rats...how about the basement computer?

[Zeljko]

Same thing. Built in. I phoned the customer service line for the router the other today. He was just as baffled. He told me to phone the basement computer manufacturers to see if there was some kind of hidden setting or something. I think he was reaching, but right now, it looks like the only thing I got left to try.

[dsenette]

it's possible that that card is indeed NOT working...even though it seems to claim that it is...

let's try one thing

with teh basement computer plugged into the router
get back to the screen where you saw the two network connections..
right click on the rhyne one and choose properties...then click on tcp/ip and choose properties.
now let's assign a static ip address
for the ip use a number that is 1 digit higher than the ip your wireless card is getting (i.e. if the upstairs machine's ip ends in .2 make the downstairs one .3)
then put the same subnet mask and default gateway as the upstairs computer

can you ping the router now? (start > run > cmd> ping <your default gateway ip>)

[Zeljko]

Nope, it said host unreachable. I'm curious about one thing though, when I manually put in the IP address, gateway default and subnet mask, there was something below it about putting in a DNS address or something. Is that of any importance?

[Zeljko]

and if the card is not working, why does it work, when I connect the modem to the basement computer without any router? It's bizarre.
