88x2bu VS RTL8812BU

I use an Archer T3U to use wifi off of my desktop machine. It doesn't have a linux native driver, but this one works for me so far.

I use this driver instead, but I think it all comes down to what does your wifi card need. You can download the driver in another computer and then pass it with a usb stick or, connect through your mobile phone via tethering and then download the driver directly in your computer

I installed DKMS and this 88x2 github driver recommended by this post.

Device connects and functions properly in normal operation with the following driver: https://github.com/morrownr/88x2bu.git

My original rEFInd configuration got overwritten by the non-graphical GRUB from HoloISO. However, I was still able to boot into all OSes. I went ahead and booted into SteamOS to test. My WIFI dongle was dead, so I used my phone in USB tether mode to have internet access. I downloaded the drivers for my WIFI dongle from my usual source off Github (https://github.com/morrownr/88x2bu). I booted back into Ubuntu and re-installed rEFInd so I can have the GUI OS selector.

Seems like you have to use a third-party driver from github. Probably this one. Carefully read the instructions. Also you should install additional firmware for your card. Good luck.

I use the TP Link Archer T3U which has an RTL8812BU WiFi chip. The driver can be found at https://github.com/morrownr/88x2bu but needs to be compiled (instructions are at the web page itself).

He'll have to compile the kernel module from scratch. Here's a git repository for the Realtek RTL8812BU and RTL8822BU driver: https://github.com/morrownr/88x2bu

RHEL 8 is a 4.18 kernel, this driver might work as it is tested with 4.15. Realtek drivers are known to be annoying, unfortunately they are in a ton of USB dongles because they are so cheap.

sudo apt update sudo apt install -y dkms git bc git clone -b v5.6.1 https://github.com/fastoe/RTL8812BU.git cd RTL8812BU make sudo make install sudo reboot

You bought an adapter with no linux support. A short google search shows that thing uses a Realtek RTL8812BU chip. It looks like there is a 3rd party driver made for linux at https://github.com/fastoe/RTL8812BU but it requires you to clone and compile it.

Later, wife noted wifi was not as good in particular part of house so installed a RTL8812BU wifi adapter using driver from https://github.com/fastoe/RTL8812BU.

Is it https://www.brostrend.com/products/ac3? I ask because I bought https://www.ebay.com.au/itm/284231856690 and followed instructions here, https://github.com/fastoe/RTL8812BU - instructions are different depending on kernel. Yours and mine use the same chipset.

The sophisticated driver from https://github.com/fastoe/RTL8812BU expects the mentioned kernel image vmlinux in the standard location

I downloaded this driver: https://github.com/fastoe/RTL8812BU/tree/v5.8.7 and hoped to easily install it offline, but it didn't work. Terminal tries to download metadata, but obviously it's not possible without internet. Compiling it gave also an error, if I remember correctly it said that it couldn't find anything in temp build folder? DKMS can't be installed either. I also tried to download it on my phone and move it then to Fedora (like I did with the WiFi driver), but it wasn't possible to install it because of too many dependencies that I have no access to...

sudo apt update sudo apt install -y dkms git bc git clone -b v5.6.1 https://github.com/fastoe/RTL8812BU.git cd RTL8812BU VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER} sudo dkms add -m rtl88x2bu -v ${VER} sudo dkms build -m rtl88x2bu -v ${VER} sudo dkms install -m rtl88x2bu -v ${VER} sudo modprobe 88x2bu sudo reboot

Had no WIFI option at all. Downloaded this driver (RTL8812BU v5.6.1, for 5.10 kernel) on my phone and connected it then to my PC, so I can install it: https://github.com/fastoe/RTL8812BU/tree/v5.6.1
