Hi,
I have a 2022 European CUPRA Formentor with MIB3, originally configured for Europe/Germany and later exported to Tunisia.
The 5 GHz Wi-Fi used to work before, so the car/MIB hardware is 5 GHz capable.
The MIB was later reset, and after the reset I had regional configuration problems. In particular, GPS/navigation was not working correctly.
This was fixed by changing the navigation region to:
Country_Navigation = NMAfrica
and using the North Africa maps. After that, GPS/navigation started working correctly again.
However, the 5 GHz Wi-Fi is still not working.
The car broadcasts My Cupra 4396 normally on 2.4 GHz (channel 6). Wi-Fi Analyzer sees it with a strong signal (~-45 dBm).
On 5 GHz there is no signal from the car at all. Wi-Fi Analyzer detects other 5 GHz networks, but no CUPRA SSID and no strong hidden BSSID. So it looks like the 5 GHz AP is simply not starting/transmitting.
In 5F, I have:
wlan_module = activated
WIFI_Hotspot_2_4GHz = On
WIFI_Hotspot_5GHz = On
wifi_client_mode_2_GHz = On
wifi_client_mode_5GHz = On
5_ghz_wlan = On
app_connect_over_wifi = Yes
google_android_auto = On
apple_car_play = On
wlan_aps_to_ccu_routing = On
channel_number_for_2_4GHz = 6
channel_number_for_5GHz = 12
channel_band_width_802_11ac = 40 MHz
I tested same_ssid_for_2_4_and_5_ghz = No, 40/80 MHz bandwidth, and also channel_number_for_5GHz = 0, with no change.
The car has module 75, but searching its adaptations for WLAN or WiFi gives no results.
One thing I suspect may be important is the regional configuration:
Country identification, country of sale HMI = DE
Country_Navigation = NMAfrica
Country of sale HMI is a free-text field in OBDeleven, so I haven't changed DE because I don't know the correct value or whether it controls the WLAN regulatory domain.
So the main question is: since this is an EU car where 5 GHz previously worked, could the MIB reset + change to the North Africa navigation region have left the WLAN regulatory domain/dataset incorrectly configured, causing the 5 GHz radio not to start?
Does anyone know which MIB3 adaptation/dataset controls the WLAN country/regulatory domain, or what channel_number_for_5GHz = 12 actually represents?
A comparison with a working Formentor MIB3 exported from Europe to North Africa/Tunisia would be especially useful.
I can provide the 5F/75 part numbers, SW/HW versions and full OBDeleven adaptations if needed.
