Usually we don't add individual drivers.
from dietpi.
Since not all raspberry pi's have internal wifi ,i must use an external USB wifi,but both of them I mentioned before are not working..
If possible in a future release to add a package with all the missing wifi chipset drivers to be installed if necessary and if wifi hotspot mode is selected from the software list to be installed.

It should work with the new kernel version. Please try our migration script. However, note that this cannot be (easily) reverted: #6676
EDIT: I think I mixed it up with RTL8821CU/RTL8811CU, not sure whether one of the RTL88* drivers added with Linux 6.6 is compatible with RTL8812AU: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/realtek/rtw88/Kconfig?h=linux-6.6.y
Here the particular drivers available with the new RPi kernel:

If none is compatible, it needs to be compiled manually. One commonly used repository is this one: https://github.com/aircrack-ng/rtl8812au

All this are a little to much for me,tried an old atheros AR92xx it worked,but the performance is very poor,is the bookworm os too much/heavy for the very aged Raspberry Pi 2? Should I put dietpi bullseye will.it make any difference?
Thanks
from dietpi.
Normally the performance difference between Bullseye and Bookworm should not be that big. Do you have the poor performance with the plain operating system or a specific application?
from dietpi.
No only with the hotspot,I checked with htop there not big CPU usage.strange.can be my atheros AR92xx,what USB wifi chipset old or new,is suggested for best hotspot performance??
from dietpi.
We never tested WiFi performance, just some adapter in general https://dietpi.com/blog/?p=3266#issues_with_external_wifi_adapters
probably @StephanStS could comment on this.
from dietpi.
Thanks, do you know what country can i put to have channel 12 and 13??
And is there a way to set the 20/40mhz channel width?
from dietpi.
Nevermind I put channel 11 channels 12,13 are not working the hostapd is not starting I have GB country set
With channel 11 I get the max 20mbps
Not bad
Thanks for your help
from dietpi.
Hi again,in armbian this chipset is working if you install the armbian-firmware-full package,maybe you can add this package to dietpi to install it if hotspot mode is selected,or just the wifi drivers from this package to be installed only
Thanks
from dietpi.
I am trying to find out which firmware binary is missing. There are multiple ones which seem matching. Can you please check for related kernel errors? There should be one about a missing firmware binary, when the WiFi driver loads:
dmesg -l 0,1,2,3
EDIT: Ah lol, we are talking about Raspberry Pi, not Armbian-based kernel. This makes it more complicated to properly add the firmware binary, since we use the regular Debian firmware packages there. But at least you can then just manually download it.
from dietpi.
That command does not show/do anything
I can see the wifi adapter with lsusb command though
from dietpi.
Ah, Linux 6.1 does not contain the rtw88
drivers yet. If would be a one-way ticket, unless you create a full SD card/drive backup, but you could try whether upgrading to the new kernel/firmware stack with Linux 6.6 helps, which I suggested above already: #6676
bash <(curl -sSf 'https://raw.githubusercontent.com/MichaIng/DietPi/dev/.meta/dietpi-rpi-firmware-migration')
Alternatively, if you have a spare SD card, we host images with this new kernel:
- For RPi 2 PCB v1.2: https://dietpi.com/downloads/images/testing/DietPi_RPi234-ARMv8-Bookworm.img.xz
- For the older 32-bit-only RPi 2 model: https://dietpi.com/downloads/images/testing/DietPi_RPi2-ARMv7-Bookworm.img.xz
