Can't connect to WiFi Extra after update to Android 12

[Jelle]

Yesterday I installed the OTA update of Android 12 on my OnePlus 8T. One of the things that broke by that update, is connecting to the WiFi Extra network in the underground.

Before the update it always connected automatically (i.e. it was set up correctly), but after the update it didn't connect anymore. When I try to connect manually, I get shown a confusing screen with WiFi settings where I need to enter a password. I'm assuming that this is the configuration that used to be set up automatically, but has somehow been erased with the Android 12 update. How can I get this set up again?

I'll make a screenshot of the configuration screen next time I'm on the underground.

Ask Google when they are going to fix the bugs in their software...  @SoulfulLady 

Nothing o2 or any network can do about it.

I had the same issue. To fix it, click on EAP method and then choose Sim. I should then have a similar screen but does not ask you to put a username and password. Once you connect it will automatically connect via your sim.

Not sure why you commented on a year old thread on the old WiFi Extra network on the Tube, which has been replaced by EAP Sim Auth.

I recently updated the OS on my OnePlus 7 Pro and experienced this same issue. This is the first thread that comes up on Google when I tried to resolve this issue. I couldn't find a solution for months and it was only by chance that I played with the EAP settings that I managed to fix it.

As this is the first thread, I thought it would good to share this in case I'm not the only one who has experienced this recently.
