It worked! (kinda). With that driver, I can now connect to internet using a cable. However, the wireless still is not working. When I clicked "troubleshoot options" it suggested that I ensure an ethernet cable is connected to both the computer and the router. No mention of wireless networks at all. If you have any suggestions for this, I'd be really grateful.
But either way, thank you so, so much for the help! Even using the cable and connecting my computer all the time is better than no internet at all. Thanks again
