I'm having trouble connecting to my in-house server (Windows), but only over WLAN. Normally, this wouldn't be a problem, because I could just connect via ethernet cable and be done with it. However, I recently upgraded to a MacBook Air, which doesn't have an ethernet port.
It does work sometimes, which to me, makes things more complicated. If I keep refreshing the page, it'll work for a little while, but it will give me the "can't connect to server" or a similar error soon after.
My wireless IP address starts out the same as the server address (192.168.111.XX).
I'm not sure what other information is needed, but I'll gladly provide it!
