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?

 

[dani6767]

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.

 

[dani6767]

I still waiting for new instruction from Lenovo

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

 

[dani6767]

No, tablet is not in case.

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.

 

[dani6767]

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.
