Driver doesn't load

[lbirkert]

First of all, thank you for sharing this. I have an old laptop with a Intel pentium 3 (x86 no sse2 support) and installed debian 11 (linux-image-5.10.0-10-686). I bought a wifi adapter (TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]) which required this driver because the driver on the official tplink page was too outdated for my kernel version. I followed all the necessary steps on here. After i rebooted i typed sudo lshw -c network but there was just my ethernet card built in.

Full stdout of sudo lshw -c network:

What was a bit weird was that the stdout of sudo update-initramfs returned following:

update-initramfs: Generating /boot/initrd.img-5.10.0-11-686

lsmod doesnt contain this driver neither.

stdout of sudo dkms status:

rtl8192eu, 1.0, 5.10.0-10-686, i686: installed

It seams like it is installed on the wrong kernel version?!?

Okay i rebuilt the driver and now everything works

firmware d102e_ucode.bin for driver e100 missing

How I can fix it? Method A. Do steps: 0) My board's driver mount to my laptop on /media/a/rootfs 1) cd /media/a/rootfs/lib/firmware/ 2) mkdir e100 3) copy d102e_ucode.bin to your board's drive sudo cp /home/a/myb/d102e_ucode.bin /media/a/rootfs/lib/firmware/ 4) Now it should be work.

Or use alternative method B. Just set this:
