(Solved) USB wifi - and how to search

[notned]

I should know this. I'm plugging in a USB wifi adapter into a desktop computer. The next step is adding a new connection, but it's not intuitive. Is there a guide that I'm not finding?

First place to start is knowing if the driver is installed for the chip.
Go to menu then Administration and Driver Manager. Does it suggest any driver for you usb wifi card?
Does the machine recognize the card when it's plugged in?
does it show up in the list in network manager?

[notned]

The driver doesn't seem to be installed. I tried downloading the driver from their webpage and installing it with the command line but that didn't work. I ended up in sudo hell. It seems my next move will be to drag the whole setup back over to the ethernet.

actually the next step is to post the output of lsusb, then we can point you towards the right guide

Realtek is the one that disappeared when I unplugged the modem. Thank you to you both for your patience with me.

there's a driver here for that - https://github.com/fastoe/RTL8812BU

[notned]

Sorry but I need a little more guidance.

Try this, one line at a time:

Code: Select all

sudo apt install git dkms
git clone https://github.com/cilynx/rtl88x2bu.git
sudo dkms add ./rtl88x2bu
sudo dkms install rtl88x2bu/5.8.7.1

Reboot

Thanks for the step-by-step. I thought we were working on putting the driver on a flash drive and walking it over. This seems different.

[sleeper12]

Yes, you want to run each of those commands in the Terminal (best to copy & paste each) & hit Enter after each one. Then reboot.

[antikythera]

that's the same principal as the page I linked to which also installs a dkms driver after compilation. unfortunately it is not available as a precompiled driver even from realtek themselves who only have a windows driver listed.

[notned]

Shouldn't usb be in the path? Is your plan to drag the setup back to the ethernet?

[sleeper12]

If you run those commands while connected by ethernet, it should install the driver & get the wifi working.

[notned]

Got it.

[antikythera]

If you run those commands while connected by ethernet, it should install the driver & get the wifi working.

also, you won't need to run them ever again unless you reinstall. so when everything is working properly, you may want to take a backup with foxclone or clonezilla. foxclone is more recommended especially as the developer is a member here if you run into issues with it.
