My xperia disconnects from home wifi

[Moreton]

Hi, I have the Xperia Z3, Until recently, my phone was fine. About 3 weeks ago it started disconnecting from my home wifi, this is extremely annoying. It does it when it feels like. Mostly when ive been idle for a bit, but does occur at other times too, in the middle of a written conversation it disconnects.

Things ive tried:

Resetting Router, moving it.

Resetting apps on phone to default.

Forgetting the Wifi connection and re connecting it.

Its doing my head in now need it sorted.

Any suggestions / fixes?

Just turned it off, I will update you in 24hrs maybe less , see if it fixes it. Appreciate the reply

[Moreton]

Still disconnects. Dont know what to do

[Gadgetnutter]

I am assuming you have checked in the Advanced WiFi options that "Keep WiFi on during sleep" is set to "Always"

[Moreton]

Yep, its on always. never changed it 

Going to replace my router see if that fixes it

The only resolution I can see here would be attempting troubleshooting with the router, the worst case scenario may very well be a replacement router, however you are best to seek assistance from the router manufacturer first.

Have you not got a friend whose wi fi you can try,if it works on theirs you know the fault is more than likely your router
