Tethering/hotspot problem with Z3 after Lollipop update (23.1.A.0.690)

jonmorris — Wed, 18 Mar 2015 13:32:12 GMT

Since doing the update, I can no longer share my Internet connection with a computer, using a Wi-Fi hotspot or direct connection (USB tethering).

In both cases, I can still set it up and my Mac connects via Wi-Fi (but with 'Internet unreachable') or USB (red in Network settings) - even though I have a working connection that I can use fine on the phone itself.

It worked fine with Kitkat and the APN settings are unchanged.

At least one other person on Xda-developers has confirmed the same problem so far, and I suspect a lot of other people may not be aware as yet, or have not even realised the problem lies with the phone and not their data connection. Suffice to say, I am sure many more people will be noticing this in the coming days/weeks.

To give further information, I am on Three (UK) with the One Plan that offers unlimited tethering.

Advice?

But the firmware you updated to is Supported by threes tethering settings?
It could be anything within the firmware, especially the modem part that is not allowing the tether from an uncertified network.

Three UK has added a new APN for its new tariffs that are limited (tethering) and I believe it's called '3PortableHotspot' or similar. It's currently only used on iOS devices, where Apple allows networks to separate ordinary data and tethered data.

Android doesn't appear to have any such way to separate this, and the Z3 has no way of letting me select a separate APN for tethering, and in any case I actually use the same settings anyway.

But the z3 firmware you currently are using, is not meant for three UK, this is exactly why each network gets to customise the modem settings of a firmware before release.
I know though what you mean as in it works for mobile Web browsing but not when tethering..
It's probably an error when simultaneously using WiFi and data
I'm waiting for a UK or at least western Europe version before I reflash

I've installed the generic firmware, not a network specific version.

It must be a problem, and I've read elsewhere that there are tethering issues on other Lollipop devices.

I can confirm the same problem now exists on the Xperia Z2 after the Lollipop update.

There appears to be a fix here;

http://forum.xda-developers.com/z3/general/lollipop-tethering-t3058923

which contains a link to this; https://pmf.silvrback.com/fixing-tethering-on-android-kitkat

Bad news if it means we're going to see more Android devices coming that restrict/block tethering, but of course that's what the networks want - or at least to be able to tightly control it, and charge extra in some cases.

But you can't make that statement based on a firmware your network hasn't certified or tested for its services,
Once three devices get the certified and tested firmware for those devices on that network configuration, then you can judge it as released, until then it's your choice to use the firmware from another region and your risk too.

Ok both Z3 and Z3 compact got the ota updates yesterday and hotspot does not work on 3 UK.Both are sim free,so would have recieved the Customised UK version.Devices can connect to phone but can:t connect to internet.Looked at apn settings and no APN for 3 Hotspot which the Nexus 5 has as well as the 3 three uk one.The phones do connect to internet by data so 3 apn is correct.Spoke to 3 they say it's Sony's problem.I have sent a PM to Rickard about this.I do know about the fix on xda but that would not be any good for a customer who know's nothing about phone software

How I fixed the problem:

1- Install Java

2- Download and Install Android SKD from here https://developer.android.com/sdk/index.html#top (It dosen´t need to install Android studio!)

3- Pay attention where it went. Mine went to:

4- The important file there is "adb.exe".

5- If you don´t have this file, you need to install it. Run android SDK, tick Android SDK platform tools", tick "Updates/New" and install packages.

6- Now you have "adb.exe".

7- Now on your phone. Go to: Settings - About Phone - Builder Number (touch 4 times to enable Developer mode-

8- Return to Settings, then Developer Option and tick USB Debbuging.

9- Connect your phone to your PC (USB cable)

10- Time to Search "cmd" on your computer. and open Command Prompt

11- That black weird rectangle will appear

12- Go back (cd..) and forward (cd) until you reach "platform-tools"

13- ENTER and will appear a lot of words. Then you have to write adb shell and then tether_dun_required 0

14- Turn you phone OFF, then ON and it works!

@Rickard The 3 UK firmware tethers without a problem.The customised UK firmware will not tether even if you put all the right APN settings in.Did work for about 5mins then stopped.Hope that helps.I have flashed 3UK firmware

Z2 user on three network here with same problem.
Am at my dad's with my son the weekend and the only Internet is the tethering from my phone.
If there's a fix without needing to contact to a computer within the next 8 hours (wishfull thinking) then it would be very much appreciated.

Also Is there a non complicated way to role back to previous android??
