New computer will not connect to wireless network

[imported_wuzilla]

It might just be that it's late and I'm tired, but I'm really stumped right now...

I just got a new desktop computer to compliment my laptop. I've set up a wireless network in my house, and previously, it was just the laptop and a desktop connected to the router 2 floors up. I've added this new computer, installed a wireless card (btw this is a linksys 802.11g setup), and installed drivers.

Here's the kicker. The computer is detecting several other networks in my area (3 - none encrypted) but is not detecting the network in my house. I don't think it's a physical problem, because I'm writing this from my laptop right next to the new computer.

Any suggestions?

Do you have broadcast ssid on in the router? If not, you may not be able to detect the network. Also, if the network is encrypted, make sure that you enter the passcode and the correct network name and it will work.

In my support of hundreds of different wireless networks, I have found that most of the time when a PC can detect other wireless networks in the area but not the one it is supposed to be finding that either:

a) It is one of the various cards on the market that simply cannot see a wireless network with SSID broadcast disabled, in which case ANT80's suggestion would be appropriate (and easy to test).

or

b) The router is operating on the same wireless channel as other routers in the area and the wireless card in your computer is getting a better signal from one of those routers so it is ignoring your router and trying to talk to the 'stronger' router on the same channel. Try changing the wireless channel on your router (channels 1, 6, and 11 are good numbers to start with) to see if your computer is able to see the router on a different channel.
