After upgrading to Lion, I have no wireless network. I'm using a EDIMAX EW-7811Un Wireless Nano Adapter. It worked fine prior to upgrading to Lion. I contacted Edimax and they sent me a 10.7 driver. Still no luck. I'm running Parallels and it can see local wireless networks, but won't connect. In Lion, it doesn't see anything. I'm using a 2006 Mac Pro. Any suggestions on how to fix this? Thanks
