Hi,

I have tried a lot of firmwares and also solution that is posted on https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R7000-SLOWS-WAY-DOWN-with-Firmware-1-0-9-10-went-back-to-1-0-9-6/td-p/1383306

1.0.9.12_1.2.23 -> very bad performance I loose more than 150 mbps

1.0.9.10_1.2.21 -> the same problem. Dropping more than 150 mbps

1.0.9.6_1.2.19 -> performance is better but I still loose download speed 20 mbps

1.0.7.12_1.2.5 -> performance is better but I still losse download speed 20 mbps

1.0.7.10_1.2.3 -> performance is good. 

I have tested it with Cable and Wifi.

Please check what is going wrong after version 1.0.7.10_1.2.3 ?
