Wifi broken after update

[RichW]

Hi,

Got a fairly major issue with my Sony Experia Z3 (on Virgin mobile contract). Had an update and now wifi and bluetooth won't turn on. Turning on it just flicks back. It's not my home wifi, and is definitely a software issue on the phone, (was working all day, updated as soon as I connected to my home network when I got back in the evening). Have tried restarting, factory data reset and re-installing 3 times via PC Companion. Nothing works.

Is this a known issue with the latest update? Will there be a patch and if so when? Or is their a way to rollback and disable updates for the time being. Being a web developer I use my phone daily for testing so it's pretty useless at the moment.

Thanks

I'm sorry to hear that. As far as I know this isn't a general issue with the update, so I suggest that you raise this with your local support team to proceed with this in the best possible way.

It's not a known issue with the update so this sounds very strange,

@RichW and @shsamatdmd

Are you by any chance familiar with using ADB and if so, would it be possible for you to provide me with a kernel log using dmesg?

I too encountered this problem back in June (Wi-Fi died overnight), and after a week of trying to resolve it through resetting and repairing the phone with PC Companion, I sent it in for service. It's come back twice with the same problem.

Wi-Fi, Bluetooth and FM radio are all inaccessible. All three are handled by the same Broadcom IC.

The service center keep insisting that when they've reinstalled the system software and reset the phone, Wi-Fi has been working. But both times I went to pick it up at the store, Wi-Fi and Bluetooth were still/once again inaccessible. Sony also won't let them replace the motherboard under warranty.

Now it's in for a third and final attempt, and I've requested to have the phone replaced.

I think it's either a hardware fault or incompatibility between the system software and a specific hardware revision.

No, and I'm thinking about replacing my phone. this happened before but after the latest update wifi and Bluetooth won't turn on at all.

Dears,
after updating the android by one month suddenly the Bluetooth & wifi not working and I tried many things such as :-
1. Clear data of Bluetooth via app management setting.
2. reset the mobile and turn off using the volume button.
3. Factory rest.
But the problem is that I purchased it during my visit in Saudi Arabia and I now work in Egypt and couldn't to go the orgin agent in Saudi to let fix it and I called the agent in Egypt and he informed me the warranty not cover me cuz I purchased from another country... Please I need your help.

hello, I've been using Sony z3 for a while now and never had any technical issues. However, couple of days ago both my WiFi and Bluetooth started crashing then they stopped working at all. It doesn't work when you click on the icons from notification bar or from the settings either. I have already factory reseted my phone and it still doesn't work. Anyone ever experienced this as well and knows the solution? Regards

I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory.

Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
