LuCi displays it as generic unknown which is fair as it's not any particular brand name. I have the following packages installed

kmod-rtl8192ce - 5.15.167+6.1.110-1-1

So I'm just confirming if anyone else had any luck with this type of adapter

Looked at the GitHub link you were given in your old thread?

[karneaud]

@frollic yes but......what EXACTLY am I "looking at"?

[frollic]

At, or for ?

The entry for the RTL chip you use.

[karneaud]

Ok so i took a deeper look at it and i realize that if i need to use the particular drivers i need to use 6.2 kernel and I currently use 5.x( based on LuCi overview)

My question now is can I use sysupgrade to upgrade to a snapshot ( using LuCi) or do I need to install a fresh snapshot image?

[frollic]

Did you check the rest of the columns ?

[karneaud]

Yeah just realized they are not recommended so I guess this ones a loss as well.
