Welcome to Android Central! Does this only happen on your home network, or on any network?

Is the firmware up to date on the tablet? Have you also tried the suggestion of turning on Airplane Mode, then turning on wi-fi again?

I was with last update . After update was worse than before.I tryed the suggestion with airplane mode.From Lenovo support sent to me instruction for hard reset. The result is nothing. I still have the same problem.

Is the tablet in a case? If so, see if it helps to take the case off.

Sorry, it's hard to say if it might be a hardware or firmware bug. How old is the tablet? If it's still under warranty, talk to Lenovo about repair/replacement.

I bought the tablet less than one month. I read all answers in Lenovo forum for this problem.Most of the people think is firmware bug.

In that case, you'd have to hope that Lenovo issues a patch to fix that bug, which isn't a guarantee, since that's not really a flagship device for them. It may still be worth making a warranty claim.
