RT-AC86U Slow LAN Ports

Hi,

My experience...
I have an AC86U connected to an ISP provider at 1Gbps. The maximum speed I obtained at LAN ports was 420/430Mbps, strange...
Rechecking my configuration, I observ that QoS, for whatever reason, was enabled. Maybe is default behaviour, don't remember...
So, I disable QoS and now I have 920/940Mbps on LAN ports as expected!

I hope this helps.

Regards,
