A few days ago, one of my users was having a problem getting to his shared network drives. We have two wireless SSID's broadcasting. One internal, and one external. When I checked under manage wireless networks, it just showed the external. So, I readded the internal network and he was good to go. The only one that showed up in manage wireless networks was Internal. He comes over to my desk today to tell me that it now longer shows the internal network, and only shows the external. I am so confused. Anyone have any ideas?
