Android tablet disconnects from wifi every ten minutes
Just a stab in the dark, but according to one site, you can try turning off the &quot;disconnect on sleep&quot; option.

Check your Keep WiFi on during sleep options. These allow you to specify when to disconnect from WiFi.
Go to Home &gt; Apps &gt; Settings &gt; WiFi &gt; more &gt;Keep WiFi on during sleep. Hopefully you can stop it from disconnecting at all by choosing an option .

There are other models that lose connectivity based on how you hold it or due to an old update, but these are significantly different models that shouldn't anything to do with your model.
