TP Link Archer T4U 4.16.12-300

[joeminicucci]

I just built and installed successfully on Fedora 28, kernel 4.16.12-300 with no problems, except the interface is not coming up and appear in ifconfig like it usually does after the dkms build/install. Any ideas? Thanks!

This version of the driver hasn't been updated for this specific device yet.... apply the following patch and it'll work.

Question for you: Have you had difficulty with drops? and kernel WARNING in dmesg on cfg80211 and/or 8812au?

Sorry about the delayed response. I couldnt get the patch working, perhaps because I edited os_dep/linux/usb_intf.c instead of deleting it and creating os_dep/linux/usb_intf.c_patch in place of it. Even so I was unable to build the DKMS mod, i was running into the exact same problems as the fellow over at https://forum.ubuntu-it.org/viewtopic.php?p=5045535. My solution was to use the repository at https://github.com/abperiasamy/rtl8812AU_8821AU_linux which is based on your 4.3.14 port. To answer your question, I havent been experiencing any drops and dmesg appears otherwise business as usual
