Since upgrading to OS 4 my iPad is "turning off" wi-fi connection by itself randomly. I have to go in settings and click on the wi-fi connection each time to re-enable it. Very very annoying.
Note: it's not "loosing" the connection, it is still there, but it litterally turns the wi-fi off by itself.
It's been about a week now that the upgrade was made available, and Apple hasn't even acknowledge the wi-fi problem, even though thousands upon thousands of iPad owners have been complaining about this from the start!
What the **** is going on at Apple ? Common, make my iPad work like it did on OS 3.2.2 .
Even worst, I wanted to go back to 3.2.2 by doing the restore procedure while holding the option key and choosing the previous OS file in the list, and everything was going smoothly until iTune went checking with Apple for the validity of the old file and came back with a message like: "this file cannot be used to restore the operating system on this iPad" !
Way to go Apple! They won't even let me go back temporarily to a perfectly working OS, and force this buggy crap on us. This is starting remind me of bad experiences with drivers when I was on a PC...
