Nope, tried that. Both with 6.0.1 and 6.1.
I have an iPad 4, and it can only connect to a very few wifi stations.
On both 6.0.1 and 6.1, it has failed to connect to any airport lounge wifi,
or any hotel wifi; I've tried in LA, SFO, ATL. It can't connect to wifi in
our local cafe, or in Starbucks. Actually - it sometimes does connect,
but then quickly stops passing data, usually before the first web page
It has connected at work and home, and both of these have dual 5GHz and
2.4GHz networks. I'm wondering if the problem is connecting to 2.4GHz
networks (which I think dominate in hotels because of the better range).
I'm flabbergasted that, with all the noise on the internet about wifi issues
in 6.0 and 6.0.1, there was no major attack on wifi problems in 6.1.
Apple has their eyes closed.
