Hey, i'm new here, but i really need help with something, and there seems to be a lot of people here that know stuff like this a lot better than i do.
anyway, i have this normal, medium tower like, pc from fujitsu siemens (silverline) with windows xp professional and have used windows update to keep it up to date. the computer is a pentium 4 1.4 ghz and has 256 MB RAM. So i've had this for like two years now, and it's always worked just fine. about two weeks ago though, i bought myself a laptop which i needed for school, and after that i bought a NETGEAR wireless router (wit 4 normal ports too) so i could connect both the normal computer and the laptop to the internet at the same time. i had to return the first router since it didn't work, but the second one has worked just fine, at least with my laptop. the other computer just complains that there is not network cable attached, even when there is one. i have tried everything i can think of, i changed the network card, i disconnected the router and connected the computer directly to the LAN port in the wall, i've checked all the settings (i think) but nothing seems to work. the network card is detected and installed just fine, so that doesn't seem to be the problem, and i've tried two different ones.
the weird thing is that the computer could access the internet until i returned the old router, after that it hasn't been able to do anything with networking at all. any ideas? if anyone need even more information, please ask, i really need the computer back online...
thanks a lot to anyone who takes the time to think about this for a bit.
edit: i should add that the laptop has no problems whatsoever. it works just fine both connecting it with a cable to the router or with a wireless pc-card, so the router doesn't seem to be the problem.
