Hi,
did some testing (GX12), used branch "lr1121-testing-lbt" with build option "-DRegulatory_Domain_EU_CE_2400"
Hope that this is the correct way to test, if not, please let me know hot to bulit correct Test SW.

First quick&dirty tests looked good, connection to 2 RX with LBT 3.5.6 seems to work fine. Telemtry, (re)connection etc. like using my other TX.

But Wifi Homenetwork seems to get lost every time, always goes back to AP Mode.

Until Configurator had an update you can build this PR by selecting GIT PULL REQUEST, enabled Manual mode stating both EU domains, eg:

-DRegulatory_Domain_EU_CE_2400
-DRegulatory_Domain_EU_868
-DMY_BINDING_PHRASE="***"
-DHOME_WIFI_SSID="***"
-DHOME_WIFI_PASSWORD="***"

TX Powet Menu should look something like this:

Just updated a Radiomaster XR1 Nano. Wifi seems to be dead, no AP no connection to home Wifi.
Connection to TX, telemetry etc seems to be fine.
Any Idea how get wifi working?

Solved :
--> Bind Button for 5-7 Seconds after Startup switches Wifi on.
Needs to be done after every startup, no autostart of wifi, if restarted manually, also always in AP model like the GX12

New issue found:
Regulatory Domain is set after flashing to AU915 not EU868 (which was set for building)

I'm not having any issues with wifi after flashing. It connects to my home wifi as it should. I am also not having the issue with the regulatory domain. I am building in platformio though and this may just be because Configurator needs an update or we need to do a RC build so there is a binary available.

Sorry don´t know how building in platformio works.
Cleared the platformio depencendies 1 day ago, that shoudn´t be an issue.
But you could provide a bin for Radiomaster XR1 Nano or GX12, then i can check if it´s related to the configurator bulding process. Or do a RC, which i can test.

I've updated the web-flasher https://expresslrs.github.io/web-flasher/ so you can select the branch

I've built and flashed from PIO, binary from the web-flasher (as in the screenshot) and also from the PR using Configurator 1.7.7 and I'm seeing none of these issues!

I´ll try it tommorow when I´m home from work

I redid my build from Configurator and it's definitely a Configurator issue. I believe that Configurator is somehow causing the firmware to be flashed without the options attached to the firmware. So this why it's selecting AU915 and wifi is not connecting to the home network. This also explains why there is no wifi on the RX as well, as the auto on interval is disabled.

Please try with the web-flasher in the mean time.

Verified it with GX12 and XR1, Wifi and regulatory domain works as expected when using the webflasher

Flew almost 2hrs today without any issue, RQLY always 97-100% and TX Power 10mW. Only 1-2 seconds with 100mW TX power and RQLY 80%. Tested in 2m glider with RX Radiomaster ER8GV. Alt -27m to +241m max. Distance ~500-600m

Will do more test flights in other planes, without any concern, next week.

Tested configuration:
Switch Mode : Full Res 16ch Rate/2
Packet Rate : 100Hz Full
Telemetry Ratio : 1:8
Link Mode : Normal
Model Match : On
TX Power : 100mW Dynamisch
