LG G3 doesn't connect sometimes to some WIFI.

[yosinaveh]

I have a LG G3 phone and it doesn't connect at work to WIFI most of the times, while other phone has no truble to connect.
At home with another WIFI it connects with no truble.
Please advise what can be done on the phone side or network side.
Thanks
Yosi

Welcome to Android Central
Which network are you trying to connect to? Is it saved so that it connects automatically or is it the first time trying to set it up?
And is it showing in available networks?
