MY internet got unplugged for half a day and my 8 inch MID - android tablet 4.0 is stuck at the start it wants me to enter a password even though i never put a loggin password on it. it shows the clock a loggin space and at the bottom my internet name with a question mark in it. I put in my guest password for it but it just says sorry try again.I even tried my google account password.it does not really tell you what type in. Is there a way to do a reset on it?
