No mobile internet on FP3 after 0.17 update

[Jans]

Dear all,
Yesterday, I installed the 0.17 update on my FP3. Now, my mobile internet connection is not working any longer. WiFi works fine. Any suggestions what to do? Is there an easy way to reinstall an earlier version of eOS? Thank you in advance for your help…

Yesterday, I installed the 0.17 update on my FP3. Now, my mobile internet connection is not working any longer.

Can’t confirm on 0.17-q-20210529117214-dev-FP3.

Did you already try to simply turn the phone off (no reboot, real shutdown) and on again?

The previously installed version is still there, you can switch back to it with fastboot …

FP3 latest update corrupt, doesnt work

The Fairphone 3 is an A/B device. It has two slots for the OS (A and B). While you use one slot, updates get installed to the other slot in the background. If you are familiar with the fastboot command … fastboot getvar current-slot … should give you the slot which now doesn’t boot … or “INVALID” if something went even more wrong. fastboot --set-active=a or fastboot --set-active=b … will set the slot for the next boot. Try whether the phone boots with this. The data partition is shared betwe…

Any suggestions what to do?

Have you tried Settings | System | Advanced | Reset options | Reset Wi-Fi, mobile & Bluetooth? That worked for me when mobile data stopped working after an /e/ update (on a different phone, not a Fairphone, but worth a try)

Thank you @AnotherElk! It worked… What a shame that I didn’t try this one first.

Thank you @petefoth. AnotherElk’s suggestion solved the problem.

Dear all,
sadly the issue remains. Reset, reboot nothing helped. I will try and fastboot to an older version.

Hi @UkeJay,

I also have issues with my mobile internet connection, especially when I change from wifi to LTE. I haven’t try the hint @AnotherElk suggested yet, but I work around this problem by dialing a random number or something like -100- and somehow, the mobile internet connection starts then.

I updated my FP3 to 0.17-20210621120946 and after a reboot mobile internet no longer works.

Internet via Wifi still works. Phone calls + SMS messages still work. Resetting network settings didn’t make a difference.

Settings → About phone → SIM status (sim slot 1) shows:

Network: KPN
Phone number: Unknown
Mobile network state: Disconnected
Service state: In service
Signal strength: -102 dBm 39 asu
Mobile voice network type: 4G

@AnotherElk, yes - no difference.

Ok, please check whether the APN settings for your KPN plan are still correct at Settings - Network and internet - Mobile network - Advanced - Access point names - (tap on the desired entry).
Most providers have the correct APN parameters for their plans somewhere on their websites.

@anotherelk, thank you for the suggestion!

A difference between what was programmed in the phone and what KPN advises is "APN Protocol’: was set to IPv4 but it should be IPv4/IPv6. Changing it to the latter seems to fix it.

Thanks!
