Hi,

I get around 900Mbps over the Ethernet port while checking the bandwidth using iperf3 installed on my truenas scale server on one end and macbook pro on the other.

I get around 500Mbps over 5ghz band when it is 80Mhz channel width, and it slows down (300Mbps) below this when i decrease to 40Mhz.

The router is connected to tp-link er605 router with cat 6 cable and transmitted to 1000Mbps switch in the middle.

The package says it transmits 1350Mbps on the package, so what should i do to get a speed closer to 1350Mbps?

Looking forward for your replies.

The detailes of one router 5ghz band config is:

1. Mode: 802.11a/n/ac mixed

2. Channel width: 80Mhz

3. Channel: 36

4. Transmission power: high
