How can i use self compiled kernel module

Hello Tulpenknicker,

No, i can’t update to Core 146. Since Core 142 is kernelsigning active and my Accesspoint down.
Pls see my second firewall (
Here is no RTL8812AU interface activ…



I do not carefully read your posting. I saw security… and core 141… This happens if you think you must send a quick smile to the world. Sorry

Correct, but i can’t update or i must change the firewall to other Destri. I will not stay by the old core but i can’t do without wifi asccesspoint.
Why does everyone always have to tell you what is good for me and what is not? I do not understand that.

The core devs decided to sign the kernel and to do it the way Michael posted above.
If you want support for specific hardware by kernel modules, these must be integrated into the system.
The signing is active now for some time. Why didn’t you ask for the kernel support of your device since then?

It has nothing to do with telling you, what is good for you. It is just a design decision like using the LFS model.

He has already asked long time ago but i have not found the time to add this driver.

You have to integrate the build of the module into the build process to sign the module properly. An example is the xtables-addons lfs file which build and sign some modules. After build you have to exchange the whole kernel because the key is changed at every kernel build.

Best is to send in a patch. If the driver is gpl compatible and we can include it.


Or there are compatible wireless modules which are available for only a few Euros:

Hi Arne,
thanks for Answer. I will read in and try to install the module. If that worked, I’ll send the patch.

Many Thanks

Hi Micheal,
i know this list but no one of the USB-Sticks in this list worked as ap-Mode in 5GHz. Please see my post in forum. (



Hi Olaf,

If that worked, I’ll send the patch.

please refer to if you need further information regarding development procedures. In case of problems not explained there, just drop us a line. :slight_smile:

Thanks, and best regards,

Hello everbody.

I’m to stupid.
modinfo said the modul is signed

but …
modprobe rtl8812au
modprobe: ERROR: could not insert ‘rtl8812au’: Required key not available

any Idea?

Thanks a lot


you have to copy the whole kernel from this build not just the module.

Hi Arne,

ok, but how install the kernel? I can’t find update-grub[2].
I can copy all files from /usr/share/git-core/ipfire-2.x/build/boot/ to /boot and then?
IMHO will ipfire not start after reboot when the new kernel isn’t install with update-grub.


I’m also interested in adding support for rtl8812au driver into main kernel. I have a TP-link Archer T2U Nano AC600 USB Wireless adapter which I want to use it as an AP. There are many wifi devices using this driver[[Chip1+model::RTL8812AU]]&po=%3FInterface %3FForm+factor=FF %3FInterface+connector+type=USB+conn.

It is a pity that user requests are not really dealt with or that the user is left hanging in the event of problems. I’m really very disappointed.

I don’t understand why you are disappointed.

Arne answered your question regarding what you will need to do (copy the whole kernel) and he even said that this driver will be integrated at some time.

What more can you want?

This is a support forum where people help each other to configure IPFire…


No, if I just copy the kernel, ipfire will not start. If I copy the kernel and initramfs, ipfire will not start, too. Then when I update grub configuration the new kernel has no modules at all that are signed. When I asked how I can integrate the kernel correctly, there was no answer.
I built some kernels myself and actually have no problems with that. But never signed. The request for the module is now 2 years ago and nothing has solved. Even if other users (in the old forum and also here) givin a nitice that they want the module, there is not even an answer. That is the sad thing.


I given up. My own solution:
I’ve bought a small tp-link router TL-WR902AC. This has 1 ETH NIC, a UBS power connector and 2,4 GHz and 5GHz AP-Mode. The USB-Port of my firewall is the power supply und the NIC ist assigned/connected to blue net. And is even cheaper than the USB stick.




Is there any progress on adding driver for rtl8812au in next release?

Is this one included in any of the mainline kernels?

Hmm, I don’t think so. When I’m using it on Debian or Kali, I use (compile) this driver

I also tried to compile this driver with instruction from, but didn’t succeed because of module signing … I successfully compile module, but didn’t manage to us it because of module signing …
