ever since I bought this tablet, all my wifi connection (computer, cell phone, tvpad, tablet)drop every hour or less, lucky 3-4 times aday. Call ISP, they check my connect fine, modem work fine. Call router tech line, they can't find any problem. So I do another test myself. 1,When I got no signal, reboot the modem, this didn't work. 2,When I got no signal, reboot the router, it work, but may be half hour later, stop work again. 3,I change to use another router, everything same as the first router, reboot, work awhile and no connection again. Then I remember the problem was begun I brought this tablet, so I turn off the wifi on this tablet, no more signal disconnect any more as long as I keep this memo pad's wifi turn off, amusing ,isn't it? Is anyone have the same problem as me? Any one know what really happen? The work around is now I use my cell phone as hotspot to connect the tablet to get on line. Any one have a solution? Thank you.
