A few months back, my Windows 7 PC decided it no longer wants to detect Wi-Fi connections. All of my other devices can connect to Wi-Fi just fine, but my PC says "No available connections." It connects if I plug it into a router, but I'm unable to do that at the moment. There are two wireless connections in my house and it doesn't detect either one. I tried speaking to Microsoft support, but the woman I spoke with was one of the worst customer service representatives I've ever encountered and didn't understand the problem. I've searched the internet far and wide and I've followed instructions on the Microsoft website to no avail. I'm at a loss. Does anyone have an idea of what could be going wrong? Please let me know if you need any additional information.

Is it a laptop or a desktop? Can you post your dxdiag report please?
