oops my output contains another dongle so ignore r8188eu
edit
sorry bed time for me

When it's attached: What does this show?

This probably should have been done at the outset.

Wireless throughput is generally slower than Ethernet, but 300 Mbps dropping to 40 is a major concern, and your existing internal wifi card is certainly capable of much higher speeds. Could you temporarily move your desktop closer to the signal source to see if you get a substantial increase in bandwidth?

The reasons for doing this are twofold:

1) you need to verify that that your ISP's equipment is outputting the signal speed that they claim

- and -

2) If doing the step above yields positive results, you need to identify the interference source that is causing your available bandwidth to drop by 85%.

FWIW I too have fibre internet and my new Win 11 desktop with a wired connection gets 494 Mbps (download) while my Probook running MX 21 and 25 feet away from the router gets 400 Mbps over wifi which represents a roughly 20% bandwidth drop.

It would also help if you could give us the make and model(s) of your ISP's equipment. There may be adjustments that a user can make in the router that will increase bandwidth output.

$ rfkill

1 bluetooth hci0 unblocked unblocked
2 wlan phy1 unblocked unblocked

Reboot.

wasn't sure what "uname" was. First I put in my user name shalom, then I just tried it as uname. Neither worked...

It's not installed for this or that reason: cp: cannot stat 'mt7612u.ko': No such file or directory

What happens if you just:
or
?

In the meantime we are using the code tags for outputs, especially long ones, like this:

That driver code failed to build on the 5.10 kernel. Maybe it had not been updated for it. A look at the actual page on github for it usually answers some questions like that.
Edit: yeah, pretty old.

MT7612U for Linux

Tested with latest -stable, v4.15.6

Please plug it in and run "dmesg" in a terminal. We should see some messages about what the regular mt76 kernel driver is trying to do with the thing. Please copy and paste into a message in this thread, highlight it, and then hit the code button </> above the message box.

And it's also a USB 3.0 device, so make sure to plug it into a USB 3 port for full performance.
