Today i was upgrade my connection speed to 500Mbs, but i can reach this speed only in direct connection cable to PC. If i connect through router maximum speed is 175-180Mbs download and 65Mbs upload. QoS is turned off, all monitoring/logging is turned off, VPN also not used. I found solution https://digiex.net/threads/tomato-firmware-improve-wan-to-lan-throughput-with-fast-nat-bcm-nat.13942/ but it not working.
