Get usb wifi adapter working on ubuntu?

[Shadow_Storm56]

I bought this adapter from Amazon 

https://www.amazon.ca/dp/B07T84VQ5Q/ref=cm_sw_r_fm_apa_i_8nU0EbPMBWCNZ

Could not get it working on ubuntu and now I am pretty sure it's not supported out of the box. It's a laptop I want to get internet to and the built in card is garbage. Does anyone know how to get one like this working on ubuntu? Thanks!

I'd recommend checking this troubleshooting page there is on the Ubuntu website, it's very useful

I had ran into that before but wasn't sure I was going the right direction. My device appears as realteck somthing or other

Realtek usually makes network cards and what not, I believe that may be the integrated ethernet on your pc. It must say Bus something something something, since it's a USB device (Universal Serial Bus), if it comes up as Bus something Device something and realtek after then you can probably get realtek drivers for the card for linux from their website.

The integrated is different, I know it's this one because when I unplug the card that one dissapears..

Well, assumming that it shows up under Bus and says it's realtek there should also be some kind of code there similarly to what I circled in the photo below, if you could tell me what code/text appears I should be able to hopefully find drivers for the device.

Here is the whole list

Take the stick out, wait 15 seconds, then plug it back in and do "dmesg" (obv., without the quotes) in the terminal. You'll see several lines where it says a USB-device was removed and then a bunch of lines when it was plugged in -- post those lines here.

I will do that as soon as I'm by it again. Which will be tomorrow. I guess you want to see how the system recognizes the device in order to find the best driver.

Dmesg will say what chipset it uses and whether the issue is just that you don't have the correct firmware-files installed under Ubuntu or if it's something else, so that's why.

Makes sense indeed

• Not a sir.
• You can take screenshots or even just copypaste the text, instead of taking a picture of the screen with your phone.
• The USB-stick you have most likely uses the RTL8822BU, which does not yet have a stable driver for Linux. You can try to install one from https://github.com/cilynx/rtl88x2bu , but I can't guarantee it'll work. Also, it might not be particularly easy for someone who has never compiled such before.

Hard to take a screenshot on and post it on a lc that had just enough internet connection to load a page in 5 mins. I shall try, annoying that it's so complicated

Aye, Realtek has never been friendly with the open-source community, so any drivers that we have have to be reverse-engineered and thus can take several years before actually stable, good drivers appear.

Most of my devices already have WiFi or I can use a PCI-e WiFi-adapter, so I haven't had much need for USB-WiFi. The only 802.11ac USB-stick I have is a single-antenna design and caps at 433Mbps -- if you want, I can go rummage around in the box later today and let you know, but I can't at the moment, as I dun' wanna wake the hubby up.

This old laptop has a pcie wifi adapter but it's just terrible... like my phone has full bars and decent speed but in the same spot this laptop has 1 bar that hardly stays connected. I guess I could get a new internal card.

That sounds like the antenna has come disconnected from the WiFi-card. It happens sometimes, just pop the antenna back on the card and it should work. Or replace it. Intel WiFi NICs typically work great and they're not expensive on eBay or Amazon or such, like e.g. the Intel 7260HMW AN for mPCI-E slot is about 8€ and the Intel AX200NGW for M.2 slot is something around 15€.

Oh well atlesst it's cheap to replace. It's only being used in a greenhouse side building for our staff to add/remove item stock from our square store. I normally avoid laptops myself
