Comment 12 for bug 730972

I'm not sure it is exactly the same as this, but my wireless (which worked fine in Maverick) now cannot see my wireless router. It does pick up some other wireless router nearby, but not my own. I know that my router is working because my phone will connect to it and route fine (and range isn't an issue as I'm in direct line of sight about 2m away).
