Hi - Yesterday my HP laptop starting doing this. It shows that I am connected to a network, but when I open up Internet Explorer it says page cannot be displayed. When I ping a website I get 4 replies. I also reset the WINSOCK entries, deleted cookies and temporary internet files, and did a virus scan with nothing found. I tried all I can think of and what I found online. The operating system is Vista. I have a feeling it may be malware causing this. I am out of solutions and really need some help with this.
