Could not connect to wireless network after upgrading to Mac OS X 10.8.3
I just upgraded to Mac OS X Version 10.8.3 yesterday. When I came home, I was surprised that I could not connect to my wireless broadband router (WRT54G Firmware version 4.21.5). I can see the wireless network but when I connect to it, it always gives me the message "Connection Timedout"? My iPhone, iPads and Acer notebook can connect to the said wireless network. I have an iMac11.2.
Please help.
