Mountain Lion on Mac Mini - WiFi unstable for Internet Sharing

I have a Mac Mini Mid 2010 MC270LL/A previously on 10.6.8 and everything worked fine.

I have it plugged into a Plasma TV via HDMI and network via CAT6, but it also doubles as a WiFi access point via Internet Sharing.


Previously WiFi was secured via WEP, I don't recall if 10.6.8 had anything stronger, most likely not, otherwise I would have gone WPA2.

I have now done a clean install of 10.8. ie erase hard drive, boot from USB and lay down a clean install of Mountain Lion.

Software update downloaded a new Firmware, which has also been applied and rebooted.

Now I've set-up Internet Sharing, used same SSID (maybe should have picked a new one in hind-sight), but secured via WPA2 - the only option.


Previously my Macbook Air 13" MC965LL/A, had undergone the same clean install treatment via wipe, then boot from USB and install 10.8.

The Wifi worked flawlessly with Macbook Air on 10.8 connecting to Mac Mini on 10.6.8 (Secured via WEP), no drop outs, connected even after sleep.

Even the power nap feature worked really well, I was impressed that when I open the lid on the Macbook Air, I had emails already waiting for me.


Now with the Mac Mini on 10.8, it's a really sad state, constant WiFi dropouts, my File Sharing disappears, Screen Sharing stops, it's a real pain.

I'm hoping it's not the new firmware, I guess I'll find out when I restore to 10.6.8 and see how it goes.


Anyone else have issues with Mac Mini WiFi on 10.8 ?

Re-installed a fresh 10.6.3 from the recovery dvd, setup internet sharing and it's been working beautifully.

I'm going to compare the system logs and see what's different since I left the macbook air sleeping overnight and it had done it's hourly wake while plugged into AC (System Log messages on Macbook Air overnight);

Looks clean now, it worked beautifully overnight. I re-installed 10.8 on the Mac Mini, setup internet sharing with a new SSID (kplan4), and it seems to have resolved the issue. I suspect that even though I was removing the entry from the keystore for my old SSID (kplan3), it must have other references somewhere else on the Macbook air. New SSID has forced a new entry with WPA2 encryption and all looks good for now.


Lesson for others; if you have internet sharing setup currently with WEP encryption, and you intend to install 10.8 there is no WEP option anymore, then you should pick a new SSID and use WPA2 to avoid issues like this.
