My Mac Mini is capable of 802.11a/b/g. I have an Airport Extreme that is capable of 802.11a/b/g/n. The Mini connects at only 802.11a. It is close and has a very strong signal. How do I push the Mini to reconnect at 802.11g?
Update: I’m using Airport Utility version 5.5.x.
You can disable “a” mode in your Airport Extreme !
Air Port Utility -> Your AE -> Manual Setup -> Wireless -> Radio Mode
To check what wireless mode your Mac mini is using, click at the wireless icon (top right of your screen) while holding alt :
Finally go to System Profiler -> Network -> Airport -> Supported PHY Modes to ensure Mac mini supported modes
