Ubuntu – TP-Link AC600 Archer T2U Nano driver for Ubuntu 18.04

I'm trying to do exactly the same thing

lsusb 'can' see your device, from your lsusb output above:

Bus 003 Device 007: ID 148f:761a Ralink Technology, Corp.

You can get rid of your build errors by editing the config.mk file(s) The one that looks like it's failing for you in in ~/MODULE/os/linux/.

Edit the config.mk file in that folder, appending the following to the FLAGS to the compiler. ( approx line 235 ).

-Wno-error=date-time 

so that it looks something like this:

WFLAGS := -g -DAGGREGATION_SUPPORT -DPIGGYBACK_SUPPORT -DWMM_SUPPORT -DLINUX -Wall 
-Wstrict-prototypes -Wno-trigraphs -Wno-incompatible-pointer-types 
-Wno-error=date-time**

Good luck

I had issues with pointer types so I needed to add the other one as well.

I have the same wifi adapter and had the same problem after upgrade to Ubuntu 19.10.

I posted a similar question to yours here on this site, and received an answer from @chili555 that fixed my problem and got my wifi adapter back to working perfectly. Here's the link to my question and @chili555's solution. TP-Link AC600 Archer T2U Nano USB wifi adapter not working after upgrade from Ubuntu 19.04 to 19.10

the needed terminal commands are: git clone https://github.com/aircrack-ng/rtl8812au.git
