No wifi after upgrade to android 15

/e/OS Devices Fairphone

Hello,

After upgrading my Fairphone 5 to Android 15, /e/OS 3.2-a15-20251022539003-official-FP5.

I can’t make wifi connection with the standard account on my router.

The strange thing is, wifi connection with the guest account on the same router works normal.

Did a hard reset on the router. Removed Account and network on the phone and made it again.

Tried with QR and Barcode Scanner. On the Network settings there is: FRITZ!Box 7530 x0 stored and it stays stored. no connection. Nothing works

FRITZ!Box- entry for guests connected!!!

could be either WPA2 / WPA3 mixed vs one mode only or a 2,4 vs 5 Ghz band issue.

What band is the guest network on, and what mode does it use?

I had that exact same issue and a solution :grinning_face:

Either deactivate WPA3 in the Fritzbox or Manually connect your FP5 to your fritzbox and select WPA3 (manually meaning adding a Network, type in the regular name of your network and then select WPA3 as an Option).

I deactivated WPA3 for the time being on my 7530.

EDIT: Just to add for completion, it is not a 2,4/5Ghz issue. I tried that too seperately. And the issue is also present on Lineageos.

Interestingly enough, it was fixed for me, when I turned on 2 wifi networks (2,4 Ghz and 5 Ghz) and use the 5Ghz one (I also use a FritzBox). My phone still denies to connect with the 2,4 Ghz network.

Strange behavior, Came home yesterday and phone picked up normal wifi. Today again only guest network.

Today I’m moving to an other internet provider. Lets see whats happening.

I have exactly the same problem here, and - inspired by Aetherium’s reply - played with my FritzBox WiFi settings. The solution for me has turned out to be the following one: 2.4 and 5 GHz channels on, but both with WiFi 4.

Can only agree: strange behaviour. Did not have any WiFi problem with Android 14 at all. Well, whatever the reason: it’s working again, and that’s all we all want :wink:

Interesting. I didn’t try that Option because it would break my wifi/home assistant setup but nice find nonetheless!

If you keep the Fritzbox the issue most likely will remain. Wifi of the Fritzbox won’t be affected by a Provider change.

My solution at the moment is to restart the phone. Then it works for quiet a while.

well it didnt break my wifi, since the 2,4 gHz stayed the same in terms of name. Only the 5Ghz wifi was renamed to my wifi + 5Ghz.

Today I switched on my FP5, and again there was no connection to the internet. The strange thing is that the phone ‘sees’ my wifi, but cannot connect. Behind the name of the network it says ‘Saved/Disabled’. To add something to the list of absurdities: the phone does connect with a nearby hotspot of my Internet Provider and to my Guests Network, although the former connection is a lot weaker than the one to my own network.

I wonder if I am almost the only one to have this problem with /e/OS 3.2-a15-20251022539003-official-FP5.

A smartphone without a reliable internet connection is nearly useless today. You cannot even download a bugfix, should one be available. If this persists, I consider either flashing the previous (working) version of /e/OS to it or to switch to a different Custom ROM.

Now it works mote or less.

Router ZTE H369A

Some apps wont run, some connections with problem.

Is it an option to go back to older release? when Yes where to find it.

Different ROM would be Stock. Lineageos suffers from the same problem. And that is the basis of all roms i know of for the FP5.

Very interesting info indeed. I was thinking of either giving iodé a try, check out the community /e/ OS version or going back to the previous version with Android 14. Or this whole thing is an FP5-specific problem?

At any rate it would be great if the error messages would be more verbose on the reasons for the failed connection… It is all the more confusing, because the phone does connect to other networks, just not to my default one.

I have an FP4 with iodéOS 6.9 based on Android 15 which has no wifi problems at all as a backup mobile.

You can get older versions from here: https://images.ecloud.global/official/FP5/, if you have a Fairphone 5, for instance.
