Wireless very slow on another qubes machine - how to investigate

I’m using 4.2.3 on an Rog Strix and everthing seems to work fine.
Here, the internet over Wifi is between 200-300Mbs

I just received a new laptop (Thinkpad E16 Gen 2) and even if it has support for WiFi 6 the speed, same location, same SSID, the internet speed doesn’t go above 60Mbs (max, usually below 40Mbs)

Why is that and how can I investigate as I’m pretty sure is Qubes related
(I’ll create an USB Bootable Stick with Ubuntu and try with that as well to see if the speed will go higher …)

Regards,

Are you looking at using Tor or Whonix in speed case?

ISP on both cases

What are the WiFi models in both laptops?
Maybe try to use newer kernel /firmware.

Just tried from an USB stick with Ubuntu and worked perfectly fine on Thinkpad as well.

On the rog strix I have a Wi-Fi 6(802.11ax) (here the internet is working good)
On Thinkpad E16 Gen 2 I have 802.11 ax 2x2 (here the internet from Qubes OS is extremely slow)

What template and kernel version do you use for sys-net?
What kernel version did you have in Ubuntu?

Post specific models.
Check the output of this command in dom0:

lspci -nn

And post the VID:PID of your PCI WiFi controller, it should be at the end of the line in brackets [XXXX:XXXX].
