Nighthawk X6 R8000 Slow Internet Speed
Anybody else having issues with speed after the firmware upgrade to 1.0.4.84 that just came out?? I have 1GB internet speed and before the firmware upgrade speed test would show between 920mb and 96...
Factory reset is an absolute last resort. I did find the issue. I had to uncheck Access Control. Netgear needs to fix their routers firmware. There is no good reason that having access control checked should slow speeds from 900+MB to 250MB. This leaves my network extremely vulnerable as I cannot decide to allow or block a device. This should be considered HIGH priority to correct and maybe a defect in the product.
When access control is enabled, the router has to inspect traffic. Which requires disabling ctf (cut through forwarding) that is needed to hit gigabit speeds. That was how devices released in 2013/2014 (as this was) managed to hit gigabit speeds. With ctf disabled, the cpu has to inspect the traffic and doesn't have the power to inspect in realtime at gigabit speeds. Thats why it causes speeds to drop.
