Precision 5550 poor Wi-Fi on Intel WiFi 6 AX201

Have a new Precision 5550 equipped with a wifi chip Intel WiFi 6 AX201
Now you would expect a £3200 laptop would come with a first class wifi chip but it seems like I'm wrong!

The wifi connect is very very poor, using already the latest Intel drivers but nothing has changed. The signal doesn't go higher than 120Mbps whereas a Latitude 7480 equipped with an Intel AC 8265 on the same spot goes up and over 600Mbps.

This is clearly either a driver issue or a hardware issue with the AX201 chipset.

Anyone here experiencing the same problem?
