Wi-fi connectivity problem

[Guest Darius.S]

Hello,

I have Huawei Ascend G300 and I'm having problems with wi-fi networks.When I connect to wi-fi everything works just fine, but if I stop using wi-fi for a longer time, and want to use wi-fi I'm getting connection errors (in notifications it shows that I'm still connected to wifi).

The only way to fix that is to turn off wifi and turn it on again, it's quite frustrating. Mobile networks work just fine.

Any ideas? Or maybe someone having same problem?
