Disconnect the network cable from the computer, connect to your router from the network icon in the notification area, and try accessing websites again.When the Windows desktop loads, an icon should appear in the notification area indicating that it is installing a device driver.After it completes the process, restart the computer.Check the box that reads "Delete the driver software for this device.", and click OK.Expand Network Adapters, and locate the entry for your wireless adapter (mine is Broadcom 802.11n Network Adapter).Open Device Manager (search for it, or find it in the Control Panel category Hardware and Sound).If possible, connect your computer directly to the router via a network cable (so Windows can download a replacement driver if necessary).This is what I just tried tonight, and so far it seems to be working: The network icon in the notification area would show a yellow alert triangle indicating that I had a connection to the router, but no Internet access. I too have been experiencing intermittent Wi-Fi issues on my 2011 Mac mini with Windows 7 since I updated to Boot Camp 5 (although I wasn't sure if that was the source of the problem there have been plenty of updates to Windows from Microsoft itself).
