USB Dongles for 12.0.2

    The dmesg log shows no mention of a USB WiFi device, but it shows there are USB devices being endlessly reset. An educated guess is that too many USB devices are attached to the same internal hub and it cannot supply enough current for all the devices to power up and work properly (modern or cheap WiFi dongles can require a lot of current). An alternative guess is that it has some kind of issue with the USB 3.0 port speed.

    I'd start with removing all other USB devices and see if that helps things to run stable? - If not, see if you can disable USB 3.0 and force the hardware to USB 2.0 in the BIOS/firmware config or perhaps use a USB 2.0 extension cable to force the USB connection down to USB 2.0 speeds.

    In short, the device doesn't show up on the bus correctly so we can't even see what chipset is inside to understand whether drivers are in the LE image. You did say lsusb lists the device, but on a functional level that doesn't actually mean much.

    So if I do lsusb I get this:

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 002: ID 2571:4101 BESCO KSL81P304
    Bus 001 Device 003: ID 0bda:b832 Realtek Semiconductor Corp. 802.11ax WLAN Adapter
    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

    Device 3 is the dongle. The only usb device is a low power remote control radio so there's very few devices on the system. They're both currently plugged in to the front panel port but I put the Wifi dongle on the rear port with no others on the rear and still no luck. Installing on Windows I can't find the driver link as it's giving a 404, but the instructions sow device manager with Realtek 8811CU. In the mean time, I'll try an old extension lead and see if that helps

    We don't have a whitelist for WiFi dongles. If a WiFi dongle works on other Linux distributions, then our devs often find a way to import the driver.

    So if you want to spend more time, try the dongle on other Linux OS, like Ubuntu.

    If you want to buy something new, get an Ethernet-to-WiFi adapter. The Ethernet driver is universal, and just works.

    If I grab a modern pci-e card is it likely to just work?

    As a general rule PCI cards are better supported in the upstream kernel because there are fewer chipsets and support for new chip families often starts with the PCI variant as this easier to author/upstream code for. However the real answer is /shrug as support depends entirely on the chip on the card, and most vendors have the habit of shipping v1/v2/v3 versions of a card with the chipset changing between versions; hence why we usually abstain from recommending WiFi hardware.
