Which Linux distro are you using?
I’m using Ubuntu.
Which release version?
(if rolling release without a release version, skip this question)
22.04 LTS
(If rolling release, last date updated?)
Which kernel are you using?
Which BIOS version are you using?
Which Framework Laptop 13 model are you using? (AMD Ryzen™ 7040 Series, Intel® Core™ Ultra Series 1, 13th Gen Intel® Core™ , 12th Gen Intel® Core™, 11th Gen Intel® Core™)
If is a AMD one, the original MediaTek WiFi card is a pile of crap, especially on Linux, you can replace it with a Intel AX210 non-vpro and you will be fine.
My mediatek wifi & bluetooth card has worked fine from day one. I have had absolutely no problems with it. To make the sweeping claim that these are crap on a sample of one is rather extreme.
Is not a sample of 1, in my case is a sample of 3 from different laptop brands( Framework, Asus and Lenovo).
if you look here in the forums, there are more examples.
The MediaTek issues seems to be worse with WiFi6/6E APs.
Those MediaTek WiFi cards without issues is the exception, if you Google it you’ll see.
Regarding it’s Bluetooth, you are correct it works (mouse and BT Audio).
remember that for a communication to happen, you need 2 peers.
If one peer is bad, the other will have issues too.
From experience, Wifi 6 is a real PITA as not really well established yet.
I bet they will fix all the incompatibilities over time, but I tend to stick to regular WiFI in the meantime.
Note also, that WiFi 6 makes sense when you are in the same room with no walls in between only.
When I say WiFI6 I mean the AX standard, that have a night and day difference in comparison to the older AC and N standards. On My case I use both 5GHz and 6GHz bands, nowadays 2.4GHz is unusable in any place that is not a isolated house or farm.
When I was using the MT WiFi card I could see “micro drops” in the connection (you can check with wavemon), that was cutting the apparent performance when browsing. After replacing it, now it feels 2-3x faster.
This is on a dual band (5 and 6 GHz) pure WiFi6, without any legacy devices (they all are in a different AP, for performance reasons).
