i have a Linksys WRT54G router that works fine with the wireless, but the router does not see my desktop computer connected via Ethernet and I cannot get online. I was able to get my LAN connection to work a couple different times changing settings and rebooting everything one device at a time, but I tried everything I had done previously and nothing will allow it to connect. Do I have to have a wired connection on at least one computer?

Most routers, it is best to have at least one wired connection so you can configure the router. It is possible over wireless, however, it can give you the boot, and you not get back on. The wired connection doesn't have to be permanent, just for configuration purposes.

Do you have DHCP enabled on the router? Are your settings on the computer set to "automatic"?

I don't have anything yellow or red in device manager I have checked, but as far as ip config it will be later as I am at a different location than the computer right now.

one other thing, this weekend I brought my work laptop home to use at the house and although it has been working fine for the past couple of weeks, I had to do a system restore to an earlier date and this weekend was the first time I had tried it at the house since and I could not connect. The laptop saw my wireless network, and even accepted the passcode to get on but it could not connect. It kept reading aquiring network address...and eventually unable to connect to preferred wireless network. any thoughts on that one?

Assuming now since 2 computers have issues....In my experience, this is caused by one of two things:
1) Invalid network setup (IP config, password)
2) Router issues

If Windows says "Media Disconnected" on your wired connection, something is wrong on the physical layer. Check your cables, switches, etc... Make sure that you have a green link light on the ethernet controller, as well as on the LAN port of the router or switch you are connected to.
