Hey I have a Dell with a linksys router and am having this problem. ive tried everything i can find on the search and nothing has remedied the problem so far. Its not the router as to other computers connect to it no problem. i have the right password, i reset the router, i ran a few cmd actions, ipconfig ones and a netsh ip socks catalog.reset. or something close to that. the last one worked for resolving the limited or no connectivity problem but when i opened up IE address couldnt be found. but after i reset the computer i am again facing the same problem.
got the laptop in 05 moved out in 07 and now in 09 im back and it recognizes and connects to the network but as i said limited or no connectivity. looking for some other ideas for possible fixes.
