So I have been running a 128bit secure wireless network at home. Has been working great until recently. My laptop will no longer connect to the network. Well, it connects, but has "limited or no connectivity". The two other wireless computers in the house are working as normal. I thought the problem might have been with the wireless key. I changed the key on my Linksys WRT54G (my computer as the Intel Pro wireless) and input the new key in my computer. Same problem. When I would turn the security off, it would connect just fine and I could get on the internet. Whats the problem here?
