Sony Xperia Z5 WiFi Internet

[JoSiRo]

Hi I'm having this problem with my phone, the wifi internet drops after i reach a certain distance 5-10 feet specially when I'm in my room. It has 4bar signal but it doesnt have any internet. Its so annoying and this happen to my phone only.

I already checked my router channel, change it to 6,7,8 and 9 and still doesnt work.

Tried to reset my phone a few times already and its still the same. Also tried to reset it on pc with the sony companion and still the same.

Already went to some forums and I cant find any solution.

The only thing I haven't done is bring my phone to any sony service center.

Can someone help me please.

Have you factory reset the router?

[JoSiRo]

Already done..

The only problem is my phone is the only one having this kind of problem.

it could be about WLAN antenna. You should contact with local Sony Service.

You can find contact info here

It could be the WLAN Antenna's fault.
I tried to enable both antenna using developer mode.
Its not working either.

I'll leave a comment here if it works after I go to any service center.

Thanks.

I'll leave a message

I found a solution!

But the problem is whenever i reboot my device it goes back and I don't have internet again.

Here's what I did.,

*#*#7378423#*#* I entered that code and then went straight to service test, Antenna Tx/Rx, then I enabled primary tx/rx only.

The problem is I don't know how to set it to default.

Anyone got an idea on how to set it to default??

There's no solution. Xperias can't maintain a steady WiFi connection. If a Chinese phone gives full signal from the same distance, the issue is Sonys hardware.

I just found a solution but its just temporary. Read above.
