Slow Speed on ASUS RT-AX1800U

Hi,

I have 1000/50Mbps FTTH and I'm able to reach 950+ Mbps with my RT-AX82U.

Just for creating a guide for my readers, I bought RT-AX1800U and flashed OpenWrt 23.05.5 on it.

Tested the speeds and both on LAN and Wi-Fi, I'm unable to get past 300 Mbps.

Any advice or is this the limit of this device?

Haven't tried with stock FW.

Regards

Enable soft offload, if you need roaming between 2 radios check here:

My result RT-AX54 (same baseboard, just one more LAN port) against 1000/500 FTTH without offload with all 5 mods:

Thank you for the heads up. Enabling Software flow offloading gave me 700 Mbps speeds. Enabling Hardware flow offloading afterwards allowed me to reach 930 Mbps whick is OK. Thank you.

Future version will saturate gigabit cable with soft offload (gigabit up/gigabit down)
