LineageOS 22.2: Major Internet Connectivity Issues on Fairphone 4 after LineageOS 22.2 Update

Hi everyone,

I wanted to share my experience after updating my Fairphone 4 to LineageOS 22.2 (April 2025 nightly). Since the update, I’ve been experiencing severe internet connectivity problems:

  • Wi-Fi: The phone shows as connected to Wi-Fi, but there is no actual internet access in any browser or app.
  • Mobile data: 4G/5G shows as connected, but again, there is no internet connectivity.
  • I have tried all typical troubleshooting steps: forgetting/re-adding Wi-Fi networks, toggling airplane mode, resetting network settings, checking APN and DNS, restarting the router, and even ADB workarounds. Nothing has resolved the issue.
  • Other devices on the same Wi-Fi (laptop, other phones) work perfectly, so it’s not a router or provider problem.
  • The problem started immediately after the 22.2 update. LineageOS 22.1 was stable and had no such issues.
  • Downgrading to 22.1 seems to require a full factory reset and data loss, which I would like to avoid if possible.

From searching the web and forums, it seems I am not alone-other Fairphone 4 users are reporting similar problems after the 22.2 update[2].

If you’re on 22.1 and rely on your phone’s connectivity, I strongly recommend waiting before upgrading to 22.2.

If anyone has found a solution or workaround that does not involve a full wipe/downgrade, I’d love to hear it!
Otherwise, I hope this helps others avoid the same frustration.

Thanks!

Hi @Saho, I had no connection to mobile data too after the upgrade to LineageOS 22.2. I took the SIM card out and in again, switched 4G on, tried switching the phone on and off and after some playing around it worked. I don’t know, what was the thing that really helped, probably putting the SIM card in and out. Now it works, WiFi worked directly after the upgrade.

Interesting, though it’s odd that you had to fumble around this way for it to work… I’ll try your SIM card trick but AFAIC there has been wifi for a brief moment and afterwards nada. It’s been a few days now.
