Same here. Very frustrating and disappointing. I too have to reboot after the computer wakes from sleep and the networking component freezes up. Network preferences and even clicking on the wifi menu bar further crash the system requiring a hard rreboot. I've gone as far as to remove the wifi config for the Airport Extreme here at home and rejoin but that did not remedy the problem. it does not happen all the time, but maybe 75% of the time. Anyone else see this happening after upgrading to Mountain Lion. I'm using a late 2011 MBP 15" with 2.5GHz Intenl Core i7

Yep, same here. I upgraded from Snow Leopard and it ran like a dream...no issues what so ever. I love all the new features that come with Mountain Lion and my work flow is so fluid and effient (I'm a web developer), but this wifi issue is a big issue in my book. Apple, would you kindly fix it please?

sharpmachine: I found an interesting thread where people who use the Transmit Disk Mounting MenuBar item (included with the Transmit app from Panic) discovered that perhaps, this component is part of the problem. So, I toook the advise of several posters and disabled the said Transmit menu and will report back if it solved my issues. If you are interested and want more info on this please visit this URL:
I'm glad I was not the only on experiencing this issue. One Google search releaved a plethora is complaints related this this matter.

Crazy. I indeed do have the Transmit Disk Mounting MenuBar. I never use it...i prefer to just open the app, so I have no qualms with disabling it. Thanks for the tip!

g8k3pr: I noticed your post about Transmit being active in the menu bar possibly being a problem. I use Transmit and have it active in my menu bar. I'm going to disable it and see if this works.

I have not had any more freezing or issues since disabling the Transmit icon in my menu bar. I just emailed Panic to make them aware of this situation.

!!!!!!!!!!!So far only this has worked for me!!!!!!!!!!!!!!!!
Go to System Preferences -> Energy Saver -> and UNcheck the box that says "Put hard disk(s) to sleep when possible on BOTH the Battery and Power Adaptor tabs.
I had this issue when I first installed Mountion Lion on my Aluminum MB 2008. Thought it was 10.8 so I down graded to 10.7 Lion, issue still happened. But after I applied this setting the issue seemed to go away. Before this I also deleted the old wifi settings in Network Utilities and added the Wifi device, ssid, and wep key again (not using WPA2). I will continue testing through the night and will update once I can determine the issue is gone.
Hopefully this works for others too.

I have been having the same problem. I also use Transmit and just disabled the menu bar option. Hopefully this works.

I took your advice and disabled Transmit from the menu bar and that worked! Thanks!

fsoria: I use Transmit, and found that once I disabled it from the menu bar, this problem went away. I would see if you have any programs in the menu bar and disable them. See if this works.

disabling transmit in the menubar fixed it for me too

restarter 2: I got an email back from Panic, Inc. and they said they are going to look into this issue.
