Hi my name is Jeremy, I would like to assist you with your question. I am an expert here on JustAnswer.com in the computer field.
How are you doing today?
It sounds like the wifi configuration ".conf
" file may be corrupted on the tablet. A recovery would be the only way to restore this. If you have anything important on the tabet let me know, we can download a program to backup the pictures, etc. However if there is nothing important we can simply do a factory reset on the tablet. Any purchases you have made through the Android Market would be free to re-install since you have already paid for them.
Here is what we need to do:
On the Home screen tap Settings
(or press the menu key and choose Settings)
Tap Factory data reset
Follow the prompts to complete the reset then once it finishes (about 5-10 mins) go ahead and try to connect to the wifi.
