iPad Air 2 Loosing wifi, even the symbol disappear

[wsarahan]

Hi guys how are you?

I have an iPad Air 2 cellular, but i disable de cellular data at home and only keep wifi on

The issue is if i let the ipad sleeping for couple of time the wifi just disappear, the simbol itself, just when i wake him up the wifi signal comes back and i receive a lot of notifications at same time

I already restored via DFU and set as new iPad but no sucess

What should i do? I think it`s not normal that the iPad simply disable wifi itself right? Even the wifi symbol disappear

Anyone with the same issue? Anmy idea?

Thanks guys

iOS 8.1.3, iPad Air 2 64GB LTE
