wlp1s0 not found

[wahaha 4]

I reinstalled debian onto the tinkeboard 2s, and added the below to /etc/network/interfaces

# Add the following (for ethernet):
auto lo eth0
allow-hotplug eth0
iface lo inet loopback
iface eth0 inet dhcp

 

However, when I did:

ifconfig

It produced the below result:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.50.146  netmask 255.255.255.0  broadcast 192.168.50.255

As you can see, wlan / wlp1s0 is not found in there. As such, I am unable to connect via wifi / bluetooth.

 

Is there a driver / kernel / firmware that I can use to update the drivers so that the wifi and bluetooth modules are detectable?

hello @wahaha, 

not sure if it's a hardware or driver issue, to get a little further: 

1. what is the image version you're using? is it debian 11 v.3.0.6?

2. what are the results when you execute the commands:

ifconfig -a
sudo lspci
sudo lsmod

seems like might be a driver issue? since lscpi is showing hardware results.

 

Note: I used debian 11 v3.0.6 --> but I used debootstrap to install a variant of ubuntu instead. which probably didn't install the driver (i think?)

[tooz 47]

hello @wahaha, 

looks like the driver isn't initialised, please try:

sudo modprobe 8822ce 
uname -a

 

[wahaha 4]

Yea I think it'll work. I copied the modules over. Will enable it and try. But I believe it'll work. Thanks!

Also, can I please trouble you to help upload the kernel resources for 5.10 to git so that I can customize my kernel and the modules?
