I’m having a problem with internet connectivity using the USB 2.0 Gigabit Ethernet Adapter. Windows 7 Network and Sharing center reports internet access, but none of my browsers or email programs can access web servers - everything just times out. I haven’t been able to troubleshoot it using Windows 7 because it keeps reporting no problems, so I’ve been trying the usual things with USB and ethernet cables, swapping ports on the router, etc. I have other PCs and media devices connected to the same router, both wired and wireless, and none of those devices report problems with internet access (or I wouldn’t be posting this message on another PC). The latest version of the drivers I have installed is AX88772A. Any ideas on how I should proceed?
OS: Windows 7 Home Premium
PC: Dell Dimension 8300 3.2 GHz 4GB RAM 1TB free HDD space
Plugable Device: Gigabit USB 2.0 Ethernet Adapter
Plugable Driver: AX88772A
Other Ethernet: all disabled on this PC (lightning strike took out wireless adapter and on-board Intel Ethernet, hence why I used the Gigabit adapter. It’s been running OK since last March 2012).
Router: Linksys WRT54GS Wireless-G/Wired (not the same one that took the lightning hit!
Browsers: FireFox 15.0.1, IE 9, Chrome 20-something
FWIW, I had been having numerous application problems caused by the latest version of the Avast Free Antivirus 7, which I have since tanked. The connectivity problem showed up after I uninstalled Avast. I don’t know if that means anything though.
Any ideas on how I should proceed?
