I'm running Windows 7 Pro, service pack 1, 64 bit on my desktop. I was using a Netgear N150 Wireless USB adapter to connect to my home wifi network. That stopped working, so I installed a TP-Link 300Mbps Wireless N PCI adapter (TL-WN851ND). The TP adapter has never worked, but is still attached. I know the Netgear adapter works, because I used it in my Roku successfully. I am currently connected to the internet using an ethernet cable connected directly to the router/modem. At this point I have tried so many different ways to fix the problem, I have lost track of all the changes. What steps can I take or settings can I check on my computer to make sure I didn't change something for the ethernet that is different than what I need to connect with the TP-Link wirelessly? I think the problem is with my computer, but I don't know how to check it. Thanks for any suggestions.
