Resetting the SMC [1] on my Macbook Air (late 2010) seems to have fixed the wifi issue. Obviously, no guarantee that'll fix it on yours... Unfortunately, I've had all sorts of other, less intermittent issues with Mountain Lion. Finder is extremely sluggish (beachballing a LOT), sleep can be iffy, and will cut in while a Time Machine volume on network share is mounted, leaving it in an unclean state and wanting to delete all my backups (!!!) and start over. (I've thus far worked around it with a full fsck and deleting only the most recent snapshot and updating the plist file to reflect this, but that's not really a solution as it takes a few hours at a time to do the fsck over the network) I'm also getting far worse battery life than before, as the system has 5-10% CPU utilisation when idle for no apparent reason. I'm hoping these have improved with 10.8.1, otherwise I'll revert to Lion and think about switching back to Linux in the medium term...
