Not long after updating to 3.1 i started having an issue with my wi-fi. It would say scanning, then acquiring IP address and then flash something quickly, then return to scanning and start the process over again. I tried the reset button (which didn't work) and a factory reset twice (which would cause it to work for a few hours and then restart the problem all over again). I spoke to a level 2 Acer tech (who said he had helped with this same issue multiple times today) who provided me with a few solutions if you are having the same issue: 1. use the reset button on the side of the tablet and then do it again right after the tablet reboots. if that doesn't work: 2. plug in a usb keyboard while the tablet is under power then shut it down press and hold the power button and the volume rocker that is closest to the corner of the tablet hold both until the tablet reads "clearing cache" then release the android robot should then appear press the home button on the keyboard. choose the third option the tablet will do a few things and then select the first option if that doesn't work: 3. unplug the keyboard and shut it down press and hold the power button and the volume rocker that is closest to the corner of the tablet once the tablet vibrates, release the power button but keep the volume rocker depressed while keeping the rocker depressed, flick the rotation lock switch back and forth until the tablet reads clearing data. the tablet should go through the options and reboot itself automatically. I should inform you that none of these options worked for me and apparently the giveaway was that the robot had a caution symbol (the triangle with an exclamation mark inside) I have to send my tablet in for repair which should only be 7-10 business days and i will update you when I get it back. I hope this helps some of you if you happen to run into a similar issue with your tablet.
