Trouble with 8822bu driver for TP Link Archer T3U Plus

Mon May 03, 2021 2:31 am

Just bought a Archer T3U Plus to use as a wifi adapter to use as a network scanner because the default RPi's wifi doesn't support monitoring.

I've followed these two instructions to install this device no success:
When I use sudo install-wifi, I get "Your Pi revision number is Processor type unknown - you do not appear to be running this script on a Raspberry Pi. Exiting the script". That is odd since mu uname -a output is "Linux thin-man-pi 5.10.33-v7l+ #1415 SMP Fri Apr 30 15:50:57 BST 2021 armv7l". I purchased this RPi 4 2GB just one month ago.

After trying the rtl8822bu script after a reboot, I'm still not seeing the device listed iw dev. The device is listed with lsusb

Code: Select all

pi@thin-man-pi:/tmp $ lsusb
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 534d:2109
Bus 001 Device 003: ID 2357:0138 TP-Link
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I've read these two articles (viewtopic.php?t=241593, url=viewtopic.php?f=63&t=279543&p=1765642&h ... u#p1765642) with no luck.

Any suggestions on how I can get this device to be seen so I can use it to connect to wifi?

The drivers from fars-robotics only support the Official Raspberry Pi Operating System:

https://www.raspberrypi.org/software/

Code: Select all

uname -a
Linux raspberrypi 5.10.17-v7+ #1403 SMP Mon Feb 22 11:29:51 GMT 2021 armv7l GNU/Linux
The information is out there....you just have to let it in.

Can you post the output of command

Code: Select all

cat /proc/cpuinfo
just to check the Pi revision code.

Added a couple of missing revision codes for Pi4 2GB v1.4 and Pi4 4GB v1.4.

Script may now work for your Pi.

Thank you so much. Re-ran the script, works like a charm. I now see both interfaces:

Code: Select all

pi@thin-man-pi:~ $ iw dev
phy#1
        Interface wlan1
                ifindex 4
                wdev 0x100000001
                addr 98:48:27:ce:80:24
                type managed
                txpower 12.00 dBm
phy#0
        Unnamed/non-netdev interface
                wdev 0x2
                addr e6:5f:01:13:4f:c3
                type P2P-device
        Interface wlan0
                ifindex 3
                wdev 0x1
                addr e4:5f:01:13:4f:c3
                type managed
                channel 34 (5170 MHz), width: 20 MHz, center1: 5170 MHz
