Not sure if this means that the 4.13.0-26 kernel will not load the module or not. usbcore: registered new interface driver rtl8812au 8812au: module verification failed: signature and/or required key missing - tainting kernel 8812au: loading out-of-tree module taints kernel. There is no response if I plug and unplug the adapter. The udev rules list wlan0 which is the device my adapter previously appeared as. The module information and module parameters look OK to me but I am probably kidding myself if i think I could detect an incorrect value The Network Manager profiles contained entries from my previous connections to the WIFi. The iwconfig output contains no references to a wireless device only eht0, eth1 (hard wired ethernet interfaces currently being used) and lo and similarly the network manager information for eth1, eth0, ttyACMO.
#4.13 KERNEL REALTEK WIFI DRIVERS INSTALL#
After scratching around I came upon more recent Linux versiond of the Realtek rtl8812au drivers ( ) and tried installing these using dkms (instructions used to install are in the attached file .) No compilation errors and the driver seems to have installed ok. I also tried v 4.3.22-beta from the same repository with no improvement and the same errors (Warnings about implicit declarations). I tried several fixes ( ) for this but came to the conclusion that this repository had not been up dated for quite a while. I initially tried recompiling and reinstalling the driver I had previously used rtl8812au version 4.3.14 ( ) but received compile errors which had not previously appeared. This adapter uses the Realtek 8811au chipset ( see wireless-info.txt attached ). I am having similar problems with WiFi on a desktop with a Netgear A6100 usb Wireless adapter after updating the kernel to 4.13.0-26-generic.
