Which driver uses Armbian for Realtek ID 0bda:b812 USB3 WiFi N/AC card?

OrangePi 4,

 

Question in subject as I found at least 3:

- https://github.com/morrownr/88x2bu

- https://github.com/fastoe/RTL8812BU

- # REALTEK RTL88x2B USB Linux Driver
**Current Driver Version**: 5.13.1
**Support Kernel**: 2.6.24 ~ 5.17 (with unofficial patches) (forgot URL).

 

On Armbian system "automagically" configures card after inserting, can configure as AP, only iwconfig shows as follow:

wlxb44bd62f536b  IEEE 802.11bgn  ESSID:"ARMBIAN"  Nickname:"<WIFI@REALTEK>"
          Mode:Master  Frequency:5.2 GHz  Access Point: B4:4B:D6:2F:53:6B   
          Bit Rate:300 Mb/s   Sensitivity:0/0  
          Retry:off   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=1/100  Signal level=1/100  Noise level=0/100
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

 

No mention of A / AC.

88x2bu               2506752  0

 

Driver (both Realtek and "morrownr") on x86_64 is much bigger - 3MB+.

Moved to P2P help.

3rd party hardware

lacking proper logs

armbian.com/bugs

Pls move BACK, just provided armbianmonitor -u output!.

And my question is NOT a bug report, "3rd party HW" WORKS, but I have some questions. And help choosing right driver on x86_64 PC.

Thanks for clarifying.

 

However First Bug tracker is - as the name implies- for bugs  only and second these [bug tracker] forums also cannot cover anything beyond integrated board hardware functions.

Therefore I am sorry but the topic will not be moved back. Thanks for understanding.

Ok, You want to be "strict":

- it IS a bug report:

- look at the output of iwconfig!

Card is WiFi AC and utility shows 300Mbps! It N, not AC troughtput!

Also, I have connected 2 of such cards, and iperf shows ONLY <150Mbps! Both on USB3. 2m apart.

 

I want to do some investigation, but question in subject remains also.
