Public bug reported: TP-Link T4u WIFI USB NIC worked fine for Xubuntu kernels up to 3.13.0-77 (LTS 14.04) with driver r8812au. After that, it will not work. Even with upgrade to 4.4.0-34 (LTS 16.04), WIFI still does not work. Prior to upgrade, if I booted into kernel 3.13.0-77, it worked fine. Now after upgrade, WIFI will not work even when I revert to kernel 13.3.0-77. This bug report was generated when I went into Software and Updates -> Additional Drivers (from kernel 3.13.0-77). The device was listed as "Unknown: Unknown" with radio button "Do not use the device" selected. I tried to change that to "Using dkms source for the r8812au network driver from rtl8812au-dkms (open source)" which resulted in this automated bug report.
