It was working fine until I awoke to find it had suffered a serious shutdown. From then on no internet access. I am using sn HP Probook 4525s with Windows 7 the rest of my computers on my router are fine but they are hardwired. The laptop is the only one using wireless. I also have a port for a hardwired connection and I have tried it to no use. I show a connection to the router but have no internet access. I contacted support but they only said I have a problem with my laptop and they can't help with that. I am stuck. If anyone can help please give me some advice.
