I just installed this device on Ubuntu 19.10 without any problem:

i use tp-link t4u archer v3
works fine with this driver.

I have a D-Link DWA-182 and it does not work on Ubuntu 19.10 using this driver here. I suspect that it does not work on any kernel >=5.3. Issue #27 might be relevant too.

[powderluv]

I have used it on 19.10 and 20.04 beta. What is the error? What is the PCI ID of the device?

That PCI device is supported by the driver. BUT looks like you are using some old module.

From your stackoverflow:

[ 98.065544] 88x2bu: loading out-of-tree module taints kernel.
[ 98.067018] 88x2bu: module verification failed: signature and/or required key missing - tainting kernel
[ 98.093187] RTW: module init start
[ 98.093189] RTW: rtl88x2bu v5.3.1_27678.20180430_COEX20180427-5959

You want to be using the code from this repo which should be 5.6.1+

I would suggest a full removal of the dkms and re-install. I have it running on my Thinkpad + 20.04 with no problems.

Hope it helps.

I checked again and it worked now. I am very sorry. I did so much debugging on this issue, I obviously lost track of what I did which machine and with which version.
