My polaroid tablet model a7 will not authenticate and allow me to go on internet using wi-fi

because the WPA is a protection of the wi-fi LAN where you are trying to attach

try turning the wi fi off on the tablet and then turn the wi fi back on and try to reconnect.
you may need to set up the encryption. It could be set on WPA2 and the tablet may not cope with WPA2 may need to use WPA1 on router .

Well, I may be an 18 yr. old and I may be no wiz but I'm big into computers and there are several solutions to this. 1) If there is a password put in the wi-fi, you need to: have a device in which will be able to put in the type of security and/or put in the EXACT password. 2) Make sure it is YOUR wi-fi you're trying to connect to. And 3) If 1 and 2 don't work, contact the company of which your wi-fi was bought from. I hope this explaination was helpful for your problem.

Sounds like a bad ios or may be ios get corrupted try to restore the ios file.

You need to make sure you have the right Wi-Fi password. A lot of the time you get the Authorization Error because of the password being incorrect.

if you have a "Wi-Fi box", try unpluging it and re-plug it. Or you may just be able to sit next the Wi-Fi box
