Thanks, but I need this channel. There were no problems before, XiaomiEu removed restrictions on the use of 5ghz and restrictions on regions. I think it's a bug.

OK, good luck then, there's no way for me to debug that from where I'm physically located.
Confirm, same problem here and so, no connection to wireless Android Auto. Channel in car radio cant change. Also in 22.2.9
And why MIUI 12.5 (also Xiaomi.eu rom) has no problem with car wifi?? 12.5 is also an china rom...
Edit: Find out that the car use channel 149, no connection on Mi11Ultra with latest EU rom, but connect my MiMix2s with 12.1 xiaomi.eu rom (20.9.4)

Reboot the device, then immediately start recording a log using this command:
Code:
adb logcat -s wificond,wpa_supplicant,WifiCountryCode,WifiNative,WifiNl80211Manager,WifiService > wifi_log.txtWill this help you? Its from my Mi11Ultra with 22.2.9 rom.
Iam no dev but when i look in the log´s, i dont see an channel 149 entry, last seems to be 140 in 5ghz. Also there is no frequency entry for channel 149 (5745mhz)

I am sorry, I do not know, how to record it, I tried somewhat from Xiaomi Ultra 11. Plus I send you a channel my car radio uses with another phone (vivo) for AA wireless - see attached. On 12.5.20, there were no problems connecting Xiaomi + this car radio for AA wireless. The problems started with the Miui 13. I am located in CZ.

That only means that whether CN hardware or GL/GLOBAL hardware doesn't matter, that's good.
The above logs confirm that Xiaomi somehow broke the firmware support for 5GHz bands over 5700.
This is from your logs on Mi 11 / Ultra (probably all Snapdragon 888 are affected):
And this is from Mi 10 (latest Weekly):
Notice something missing in your logs?
Which means:
Unfortunately, it's not possible to fix the firmware. Only Xiaomi can do that.

Thanks for the research, but I can't understand why then everything works on miui china official 13.0.6, but not on the same version of XiaomiEu?

Don't have an answer for that right now, I don't have a device where I can make the needed tests.
You can make a log (same adb logcat command as above) from China ROM if you wanna help out.

No problem! Research isn't done yet though, but I have a theory, would have to see a similar log from China ROM of the same version to confirm.
I have the same problem with my Mi 11 Pro. I have my router 5GHz channel set to 153 and my Mi 11 Pro cannot detect the SSID of 5GHz Wifi after update to MIUI 13 EU ROM (It works normally on MIUI 12). If I change my region to China and restart my phone, I can connect to the 5GHz Wifi Channel 153 temporary. When I am away my router for a while and get back later, it lost the 5GHz Connection again. I have to restart my phone again to detect the 5GHz SSID.
The restart method only works if I set the region to China. If I have the region in Hong Kong, it cannot detect 5Ghz network with channel 153 no matter how many time I restart my phone.

Doesn't mean much because for Wi-Fi, region is being later set to your telephony country code.
