When using my notebook at home, my WLAN connection suffers from interference between the Wifi and Bluetooth signals. If the Bluetooth module is enabled, my notebook hardly detects the WIFI signal while all other mobile devices (4 smartphones, 2 tablets) detect the Wifi signal without any trouble. If the Bluetooth module of my notebook is disabled, the Wifi connection works fine. Conversely, when using my notebook at university, the Wifi connection works fine even with the Bluetooth module enabled.
My notebook is a Asus Zenbook UX330UA-FC006T which comes with the Intel Dual Band Wireless-AC 7265 adapter. It is running Windows 10 (64 bits). I tried the most recent driver (v19.51.11.2) without any improvement. I have currently reversed to the previous version (v19.50.1.6) but I the same issue remains.
My router does not support the 5 Ghz band. I understand there may be interference between Wifi connection and Bluetooth because they are both using the 2.4 Ghz band. The university’s WLAN network may support the 5 Ghz band which would explain why my Wifi connection works fine there.
I would like to re-enable the Bluetooth without killing my Wifi connection again.
I understand from another post that the Wireless adapter uses the following antenna configuration :
Antenna 1: WiFi + Bluetooth
Antenna 2: Wifi
I suspect my notebook has only one antenna or antenna 2 does not work.
How can I check if antenna 2 works ?
