I have 4 computers connected to the network. 1 desktop(xp home) on wireless - never a problem, actually it runs perfect!!
1 laptop(xp home) of wireless - internet is slow, but aim runs fine. It is in the back of the house and that could be why. I found the antenna loose and tighted it, but have not tested the laptop.

Ok, the problem is, I have 1 pc(xp home) wired to the router and 1 laptop(win98) wired. We have had this router for 2 months and no issues. Well all of a sudden the 2 wired pc's both can surf the internet, but will not connect to the network. Nothing has changed. I checked the router and it see's all the pc's. The ip's are not expired. I can access both the wired pc's shared folders from my wireless pc's.

I have done everything possible and can not access the network from these 2 pc's.

Please help!! Thanks, Tara
