Let me summarize the difference of models based on the reference here: tinhte .vn/thread/tong-hop-cac-ban-firmware-cua-android-tv-box-x96-air.3050996/ (it’s a Vietnamese page that’s why maybe you guys could not understand it clearly):
4GB RAM version models:
X96 Air_P1 ( chip wifi AP6255, Lan 100M)
X96 Air_P2 (* chip wifi AP6255, Lan 1000M )
X96 Air_P3 ( chip wifi RTL8822CS, Lan 1000M *)
X96 Air_100 (chip wifi 6222B-SRC, Lan 100M)
X96 Air_Q100 (chip wifi Cdtech 4761743 Lan 100M)
X96 Air_Q1000 (chip wifi Cdtech 4761743, Lan 1000M)
X96 Air_A1000 (chip wifi: not mentioned, Lan 1000M)
X96 Air_A100 (chip wifi: not mentioned, Lan 100M)
You are right, there is the wifi chipset difference and we can be based on that to specify what is the model using some Linux command.
I tried on my current box (an X96mini (2GB RAM, 16GB eMMC - installed Armbian) and I can get its information using nmcli tool:
alex@arm-64:~$ nmcli
wlan0: connected to Wifi_Work
"wlan0"
wifi (**rtl8723bs**), 28:F3:66:22:F3:AE, hw, mtu 1500
inet4 192.168.1.23/24
route4 0.0.0.0/0
route4 192.168.1.0/24
inet6 2001:ee0:4b48:3420:6780:8801:4119:2ea1/64
inet6 2001:ee0:4b48:3420:9f18:9808:142c:e5ab/64
inet6 2001:ee0:4b48:3420:d370:48f9:a318:2174/64
inet6 2001:ee0:4b48:3420:c45b:12bc:f5e3:16a6/64
inet6 fe80::89a0:1cca:8ee7:d8eb/64
route6 2001:ee0:4b48:3420::/64
route6 ::/0
route6 ff00::/8
route6 fe80::/64
So when I received the X96 Air, I will double-check it using 2 ways:
- First I will check with Android OS (in the About section, it would show the model there).
- Then I will try to follow a guideline to install manjaro and try a Linux command to get the wifi chipset model to double-check.
I still have 2 questions for you @pferrante 
- Could you please help to define the wifi chipset name of your device using the Linux command and tell us here?
- You mentioned a ‘standard’ guideline, which one is it? I navigated through the forums but most of the comments I saw are: “Wifi/BlueTooth/HDMI sound does not work”, only your comment says that all works fine.
Thank you so much, I think one of the most important things is to specify the correct hardware model before trying.
