After update to WP8.1 (Lumia Cyan) my Lumia 920 don't work with signal 2g(E)

After update to WP8.1 (Lumia Cyan), my Lumia 920 doesn't take the network 2G (E) anymore. I have changhed SIM, i have done hard and soft reset, i have update again my Lumia 920 using Nokia Recovery Tool but nothing is changed, my Lumia 920 doesn't recognizes 2g(E) signal. Infact if i imposes the maximum speed of connection to 2G the smart never takes the network signal.
Can you please help me? Thank you
Excuse for my bad english
