Glad to see I am not the only one. Computer and internet were working fine on Windows XP. I did a fresh install of Windows 7 (32 bit Home) and replaced my OLD network adapter card with the DWA-525. Slow google/gmail, but it works kind of. If I try to download a file, nothing happens. No anti-virus installed yet.
I then replaced my Netgear router with a D-link DIR-655 router. Same problem. I have tried switching channels, turning off security on the router, turned of router QoS, and turned off Windows firewall. If I bring a laptop or iPhone next to this computer their internet connections works fine. I downloaded the drivers direct from Dlink and reinstalled them. Nothing. If I string out a CAT5e cable, then internet is great.
I am going to uninstall the DWA-525 (software and physically) and try a USB network adapter to see if I get my internet back on that computer.
