ok, here goes. I am repairing a laptop for a friend of mine, he said he hasn't been able to get on the internet for a while so i took his laptop home and connected it to my network. I put the computer next to my wireless netgear router and tried connecting it wirelessly, The computer said the signal is at excellent strength but it gave the error "limited or no connectivity" and won't allow me to get onto the internet so i tried hardwiring it and it still said "limited or no connectivity" Then i installed a netgear wireless USB adaptor just to see if it could be a hardware issue and it said "excellent strength with limited or no connectivity. I have tried uninstalling and reinstalling the software for the network card and built-in wireless card. I even reinstalled the chipset drivers and it still won't work. At this point i am thinking it is a windows based problem. But i am up against a wall and i have no idea how to fix this problem.
