iMac will not reconnect to wifi after router rebooted
iMac OSX v 10.8.5
3.4 GHz Interl Core i7
24gb memory
My husband stays up most of the night playing some game on his Mac. Because our Comcast wireless router seems to slow down while he's playing, he usually reboots the router before he goes to bed. For the last week or so, when I get up an hour or two after he has gone to bed, my iMac will not connect to the WIFI network until after I restart it. Once I restart my iMac, the connection is fine.
I currently have the computer set to never sleep and the display to sleep after 15 min.
