I have a 1Gb internet connection, 1Gb Ethernet with 1Gb devices. I can max out the 1Gb connection on my phone and on my laptop when the relation is WLAN-LAN, and of course on cable (LAN-LAN, LAN-WAN). My only issue with this router is the poor WLAN-WAN performance. With my phone and my laptop I can reach only about 400Mb/s speed to the internet while I can transfer data to/from my NAS at 1Gb/s.

I repeat: I can reach 900-950Mb/s on the same Wifi6 connection if the relation is WLAN-LAN, and I can reach the same speeds on cable (LAN-WAN, LAN-LAN). So the NAT performance of the router seems to be good.

I use iperf to test connection speeds:

• I can iperf from my phone/laptop to my NAS on Wifi6 connection at nearly 1Gb/s.

• I can iperf from my laptop to a public iperf server on cable connectiom at nearly 1Gb/s.

• But I can't reach more than 400Mb/s on Wifi6 to the internet, while I can reach 1Gb/s to my NAS at the same moment.

Of course I've tried some things to solve:

• I tried to reset the router to factory default, everything left at default. No success.

• I tried to downgrade firmware. No success. (Upgrade is not available.)

Is there anybody else who has the same issue?
