Kernel module for D-Link N300 WiFi 4 USB Adapter (AN3U) rev. A1

[gskillas]

Hello all,

for an old desktop I bought an D-Link N300 WiFi 4 USB Adapter. It is being recognised when inserted into a USB Port:

[Sun Feb  8 11:56:29 2026] usb 5-6.2: new high-speed USB device number 7 using xhci_hcd
[Sun Feb  8 11:56:29 2026] usb 5-6.2: New USB device found, idVendor=2001, idProduct=3328, bcdDevice= 2.00
[Sun Feb  8 11:56:29 2026] usb 5-6.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[Sun Feb  8 11:56:29 2026] usb 5-6.2: Product: 802.11n  WLAN Adapter
[Sun Feb  8 11:56:29 2026] usb 5-6.2: Manufacturer: Realtek
[Sun Feb  8 11:56:29 2026] usb 5-6.2: SerialNumber: 00e04c000001

however it is not recognised by any of the modules. Searching on the net I found
https://marc.info/?l=linux-wireless&m=175921892830898 and https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=a8e32d208ae192299bf32457924170255aaad6f7
which indicate that the chipset of the device 2001:3328 is an rtl8192fu and it should be handled by the rtl8xxxu module. In fact it has been incorporated into kernel 6.18 . Is there any chance of backporting to Leap 16.0 kernel 6.12? If needed I can provide the windows driver files.

Best regards,

George

Should be done with:

modprobe -c | grep -i "2001.\+3328"
alias usb:v2001p3328d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu

So post it.

kernel-firmware-realtek is installed?

LANG=C zypper se -si kernel-firmware-realtek

both modprobe and zypper return the shown output. The problem was blacklisting
rtl8xxxu as the D-Link DW-131 rev A1 device used before (failing wpa3) needed to blacklist rtl8xxxu so that r8712u could take over. reverting it solved the issue.

Thank you and best regards

George
