Greetings: I read every post on this issue and tried many of the fixes, but still having problems. Here is the deal, I have no clue about computers, so step by step instructions are necessary. Alright this is the problem. I have a Dell computer running Windows XP. We are staying at a camp that has a wireless service (don't know anything about it and the sys admin isn't around). The computer was working fine then would suddenly go to limited/no connectivity. Other computers are working fine (like the one that I am using now). But, the dell doesn't connect at all. Went to another location (local library) and everything works fine. Tried direct connecting it to the port in the wall and nothing worked. So, if I can get any help, that would be great. Thanks in advance to all.
