Not yet. It is just for some routers (two I have encountered so far) It seems to be extreme for that but it is a hassle if this has something to do with a few cheap/funky routers that do not work well with 4.3.2?
So have you tried starting over? If you have tried everything else then perhaps it is time to start again. Make sure everything on your iOS devices is backed up to your Mac/PC and use iTunes to restore the device to factory settings with iOS 4.3.2. Then sync it again with all of your 'stuff".
Oh I just found this thread on iphone 4's with the 4.3.2 update. Even resetting phone and then reinstalling stuff did not help:
Given it is hard to go back to 4.3.1 I guess I am stuck til this gets dealt with. I find it interesting for some the update from 4.3.x to 4.3.2 fixes WIFI problems but for a few of us it does not and/or (in my case) causes problems where they did not exist.
