slow wifi

Hey,
I am trying to get the full potential of the 9260 wifi module in my UP Xtreme I7-8565U.
Unfortunately, the connection is quite unstable and rarely makes it to ~12MB/s, but mostly only ~5MB/s, measured on the local network between the UP boards wifi interface and a laptop connected via ethernet.

In the same setup, the laptop manages a stable ~80MB/s (laptop wlan interface -> network -> UP board eth interface).

Here's the output of sudo lshw -C network

  *-network

       resources: irq:17 memory:a1300000-a1303fff

Is it possible, that the kernel doesn't support a higher bandwidth?

Best regards!
