I just updated my mid 2010 MBP to 10.7.2 and immediately suffered wifi issues. It would either connect to a network and give me a "no internet access" sign or it would not find any wifi spots at all. Tried reseting wifi, rebooting, remove and add back saved network preference, all the solutions I could find on this thread and others without avail.
Finally I took Apple's advice (saw it in the wifi icon/drop down menu) and went to system > preference > network > assist me > diagnostic WHILE I was connected to a networkout w/o internet access. Something must have happened because now I can connect to any network fine.
Hope that helps someone out there!

Well I thought that did it. I'm still having trouble with wifi and the problem seems to be worse with my home wifi network. I'm using a Linksys G 2.4 GHz router. SO I'm down to hoping that some day Apple will come up with a fix.

Same problem here.
Wifi comes and goes as it wishes... usually can be fixed turning off and on again the wifi connection on the upper bar. But it's not the way a 1500 euro computer should work, isn't it?
Also, I've noticed a slowdown... I've got 50 Mb connection, and wifi it's just SO SLOW on my macbook pro... got a Sony Vaio, and wifi works great. Same speed as with cable.
Let's hope someone at apple reads this, and try to fix it.

Having the same problem.
I updated to 10.7.2 two days ago and have been having the "no internet for 2-3 minutes after sleep" issue since then...
Apple has not given offical guidance on this?

I have now gone for nearly a month with no wifi issues. What I did was went to the Genius Bar and admitted the problem was way beyond my limited abilities. What we did was reset Safari, and deleted all of the locations ( except automatic ) in the network section of system preferences, we also ran a diagnostic to verify my 2011 MBP was fully functional. Once this was done I had no wifi issues until I got home. My 4 or 5 year old LinkSys router and my MBP did not play well together. So out of frustration I went to the Apple store and bought an Airport Extreme and I'm very happy to report that all is well on the wifi front. I don't like throwing hardware at a problem but some where on this subject I saw someone else do the same and it worked.
I am still a little angry with Apple since they still seem to think there is no problem and if they ignore the 100 plus pages on this issue alone it will somehow fix itself.
The plus of buying a new Airport Extreme, my wifi at home is smoking fast now.
I still love Apple and would never own anyting else.
