USB-WiFi VS 8821au-20210708

I've already had a look at this but unsure how often it's updated, 6 months ago according to github: https://github.com/morrownr/USB-WiFi/blob/main/home/The_Short_List.md

Just google "raspberry pi wifi adapter" or see https://github.com/morrownr/USB-WiFi

Just a note that if you're _serious_ about WiFi on the Raspberry Pi... you should use an external WiFi adapter—either PCIe or USB.

With the Compute Module 4, I've successfully tested a variety of adapters [1], from WiFi 6E to older mini PCIe and M.2 cards. There's even a board made for the purpose of multi-WiFi testing, the Seaberry [2].

The Raspberry Pi 5 works with all the PCIe WiFi chips I've tested (haven't had time to summarize testing on pipci database site yet, including a mt7921u-based WiFi 6E USB adapter (haven't written that up, but check out [3]).

Hey all, I've read the Github list of Linux WiFi adapters (https://github.com/morrownr/USB-WiFi/blob/main/home/The_Short_List.md) but I've seen sporadic comments of certain users saying some haven't worked for them. I'm a bit risk averse buying something most likely from the USA and waiting a while for it to get to Australia and it not work, so I was hoping some people could comment with their specific models that have worked for them.

It would. These should work, as clients and in AP mode. https://github.com/morrownr/USB-WiFi

Did that. Followed it to here https://github.com/morrownr/8821au-20210708. Installed it. Did not work.

i'm not a fedora user, but this github repo: https://github.com/morrownr/8821au-20210708

git clone https://github.com/morrownr/8821au-20210708.git

However I attempted to switch to Ubuntu 22.10 yesterday. Didn't go so well because my computer uses a wireless adapter that probably isn't really popular. It's a Realtek Wireless Adapter 8811CU with 5ghz and 2.4ghz connectivity. There isn't much driver support and I found a few repos to help add drivers. All the repos I tested were outdated with the current kernel for Ubuntu 22.10. (Kernel is 5.19). I found one repo, but the internet connection is extremely slow. Click for repo. So I ended up going to bed that day and waited tomorrow to probably switch back to Windows or use a lighter version of Windows like tiny11.

I am not sure what drivers you used, but these seem to be the latest for that device. https://github.com/morrownr/8821au-20210708 That URL also mentions some settings to check on your Router, and even then that driver site suggests you dont use the That device.

What is device id from lsusb output? It may be wrong chipset. Also you can try this one

Try this one

git clone https://github.com/morrownr/8821au-20210708.git

I installed it on a new empty ssd. It automatically installed some drivers but it couldn't detect the wifi adapter so I manually installed these drivers from github. Other than that, I've only installed a few stuff for my university courses and discord. I'm not sure but I think the issue started when I installed the drivers.
