Test wifi speed at ookla speedtest @ 130mbit
Test ethernet cable at ookla speedtest @ 300mbit (max provider speed)
Test iphone wifi @ 300 mbit, same provider, same router, same time. Router is Keenetic Ultra.

I think is related to antennas, I have the same problem, yet I get around 300mbps download, 700+ upload. On my previous mini PC it was connecting 2401/2401 mbps but it had external antennas. From what I seen this one is connecting 865/1200 mbps but I don't really care since I use it on ethernet cable.

Actually AX200 card is kinda weak, my previous mini PC had AX210 6E 2x2 card and external antennas, that's why it had those speeds (2401/2401 mbps and 800+ mbps on upload/download, limit of router on WIFI), since the card was 6E. This is normal for AX200.

I restarted the PC, reinstalled intel WIFI driver and got these speeds.

Everything is normal, the wifi card is working as specified.

Yes, I restarted the PC (had 7 days uptime) and I reinstalled Intel AX200 driver, got the latest from Intel site and restarted the test got those values.

This test is on LAN, ethernet cable, as you see is much different.

Hello,
Sorry for your trouble.
Pls try this:

1.Please make sure your wifi signal is full.
2. Make sure that the distance between the PC and the router is less than 6 meters.
3. Please uninstall the wifi driver and then resatart the PC to see if it works.
4. Please right click the windows ---setting -troubleshooting ---other toubleshooters--- internet---run , let the PC diagnose the problem and solve it automatically.
5.Go to device manager , click the property of the Intel wifi driver, ---advanced--choose property 802 ac, value also choose 802 ac.

Running Linux Mint 21.1.

Turned off Power Management for wifi card and solved my slow speed issues. Have hit as high as 400mbits with the service I have.
