So I borrowed a DWA-160 from a family member a few months ago (For some reason, it worked without installing anything from a disc) and I loved it. Fast and never disconnected. So I used that for about a month and then I got my own. I installed the software this time and then tried to use it. The Wireless Connection Manager will not open and whenever I try to open the Connection Wizard, it says "Unable to find Wireless Adapter." The computer itself clearly recognizes that the adapter is there, but it still won't work. At one point, I somehow managed to get the wireless connection manager open but it said that there was no network available. Please help me to get this working again.
