I was already using the android 4.0.4 tablet with WiFi at my home. Very frustrated that when I just turned it on again today it was not able to connect.
Actually, it does connect - There appears to be two phases:
- Connecting to WiFi
- Authenticating a. "Authenticating.." b. "Saved secured with WPA/WPA2" c. "Authenticating" d. "Authentication problem"
The first step is successful. The second fails at the step d.
Now, I had saved the password for the WPA/WPA2 network. So this is NOT a wrong password issue. But even so I did a "forget" and re-entered the password (with "show password" turned on to be sure).
What really bugs me here is there is no further information on "why" the authentication failed.
There are several other laptops in the home. They have not changed any settings for months (all DHCP with long leases).
