There was no problem with Wi-Fi while I was using Android Ice Cream Sandwich with my HTC One X. After upgrading it to Android JellyBean, I can find issues with Wi-Fi connection. I can always view only 1 or 2 bars with Wi-Fi signal symbol and the connection used to drop after less than a minute. I need to turn off and on the Wi-Fi to re-establish the connection. What should I do to fix this issue?
