Have Samsung Galaxy Tab 2 10.1 & wireless thru ATT Uverse. From purchase in May have had no problems with secured wireless at home or unsecured out. Today at home I get a message that "Network disabled -- Poor connection." Checking shows "signal strength is very strong" & I am posting this on my laptop using the same network. I tried: Disabling & re-enabling the network Turning off the tablet & restarting Turning off WI-FI & restarting & then re-entering password Obviously no joy! Have not added new apps in several weeks & aside from reading a book this a.m. have not used the tablet except to try to get back online. Appreciate any ideas.
