My own copy of RTL8822BU drivers

rtl8822bu's Issues

Thank you

I have removed my built-in wifi card(mini-PCIe) to add an external eGPU and while I could get the rtl8822 driver running with 17.10, my main OS is still 16.04 and kernel 4.4.x so your fixes saved me. Thank you.

The AC1200 also seems rather fast so I might end up getting one for a couple of the rPi 2's I have around and now I know what driver source to use!

Won't build on kernel 4.14

segemantation fault

I cross compiled the driver on ubuntu for ARM (QNAP NAS with marvell kirkwood SoC, Kernel 3.4.6 with the correct toolchain). The driver compiles with a bunch of warnings, but the process runs through. I then load the driver modul with insmod. When the WLAN adapter is already plugged in I get a segmentation fault. If I first unplug the WLAN adapter then the driver is loading without error, but the device is not detected when I plug in.
