Z5 E6683 wifi Drop

[ET888]

Hi Xperia Support

my E6683 is having a royal wifi issue.

My router is Asus AC-RT68P. My Xperia Z3 and Z3 Tablet compact has been working perfectly fine for last 2 years.

My new Z5 E6683 will keep drop wifi. 

This is a big issue, as if you are playing a game that requires constent internet connection, you are doomed.

My Z5 also having issue connecting to my company wifi which has a coperate level of wireless router. It will not reconnect to it, and will drop from time to time as well.

I got my Z5 and updated to 6.0 right away, so I'm not sure if it's related to 6.0 or no. But please fix it ASAP. THX

you could repair the phone with PCC, Bridge, XC to narrow down the issue.

there is nothing to narrow down.

It's the phone, not the wifi.

I tried reset the phone. I don't believe PC companion can do the magic to complete fix a wifi drop issue especially I found a lot of other people is having this issue as well.

you have 2 options, either try it or you could contact your Local support to get the device inspected.

Hi @ET888,

Welcome to the community.

There's a lot of reasons that this could be happening. There may be electronic equipment interferring with the signal, an IP conflict etc, and indeed it could be the phone. We really do need more information to determine what the issue is.

Does this happen on any other WiFi network, or just your home network?

Hi Cameron, 

please see my reply below

It can't be a electronic equipment interferring. My Z3, Z3 tablet, ipad, Galaxy note 12, anything in my home use wifi works perfectly fine.

an IP conflict etc

It's DHCP. I am a network admin. I know all my devices's IP, and I can get logs

and indeed it could be the phone.

Considering the bluetooth issue, it should be the baseband.

We really do need more information to determine what the issue is.

It happens on my home network, my coperate network, and also the public wifi I went to

Hi @ET888,

Thank you for providing that information. Based on all of that, @uliwooly's suggestion of a software repair is the correct one. The software repair is not the same as a factory reset as it completely reinstalls the OS on the handset.

[ET888]

I can certainly try that.

But why my Z3 and Z3 tablet never had this issue?

For all the poeple out there having wifi issue with Z5, I'm pretty sure someone already tried repair with software repair

@ET888,

Since this happened only after installing Marshmallow my best guess is something did not install correctly with the update.

While other people are having similar issues, there's no way to be sure that it is the exact same issue. I personally err on the side of caution and complete all the troubleshooting even if it appears to be the same thing as someone else, because you can really never know.

Hi Cameron

I upgraded to Marshmallow right after I got the phone. I didn't try it on Lollipop 

I will try reinstall software later tonight.

Do you have any update on the blutooth audio stutter fix? that's a function I use everyday. thanks
