Wifi signal problem

[Nothingtodo]

My Xperia m5 wifi performance is poor.

Also have that weird bug

I stand just two meters away from the router but the signal drops like 3 ticks.

I have tried to change router settings however that didn't make any difference. Also tried with another smartphone, signal didn't dropped.

Any suggestions?

Are you syncing or have any auto backup enabled (google photos) ?

Yes, auto backup is enabled in Google Photos. But not always syncing.
