Note: I am seeing the interface of the usb wifi key marketed as DEEPOW dongle (from amazon) changing MAC address at every boot even though I have not set up anything like that in netctl, here.

I don't know if it's a hardware problem or driver problem. However, it's the same with rtl88xxau-aircrack-dkms-git driver

Kernel 4.12.3-1 broke this for me - I #include-ed linux/signal.h and linux/sched/signal.h in osdep_service.h, and applied the 4.11.x patch, but that still hasn't worked, and there looks to be something seriously wrong. can anyone help / is anyone working on this?

Hi There is a fix for kernel 4.9.11: https://github.com/Grawp/rtl8812au_rtl8821au/pull/46 But it's not merged yet. Hope it gets merged soon. I did apply from hand :-)

To get my TP-Link Archer T4U working: git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git cd rtl8812AU_8821AU_linux wget https://patch-diff.githubusercontent.com/raw/abperiasamy/rtl8812AU_8821AU_linux/pull/217.patch patch -p1 < 217.patch followed the compilation instructions in the repo

I'm using the linked fix on an Edimax EW-7811UAC on a 5GHz network and the connection has been and continues to be superb. It's almost like having a wired one.

I'm using an NetGear A6100 AC600, and I cannot seem to get this to work. Like, at all. I'm having the same issues as Madoka, but I'll post them just for some prosperity/possible differences.

Thank you for the fix. But, this module still has issues with connectivity for me. Seems to be worse with 4.11 kernel. Constant loss of connection. The following messages are displayed with dmesg when the problem occurs, and repeats several times. Hardware is TP-Link Archer T4U V1.

Okay, I fixed the issue. You can see the 4.11 kernel fix here: https://github.com/Grawp/rtl8812au_rtl8821au/pull/42/files To get this to compile under 4.11, you need to edit /usr/src/rtl8812au_rtl8821au-[VERSION NUMBER HERE]/include/osdep_service_linux.h Add this code around line 70: #if (LINUX_VERSION_CODE >= KERNEL_VERSION(4, 11, 0)) #include <linux/signal.h> #include <linux/sched/signal.h> #endif Then, rebuild DKMS modules with "# dkms autoinstall". Until someone merges this code in the git repository, I guess 4.11 kernel users need to edit this in by hand.

I am using the linux-lts kernel because the software package doesn't like the 4.11 kernels. Hopefully there will be an update soon.
