NightHawk CAX 30 slows until Factory Reset or config restore
I have experienced this issue with this router since buying it at Costco in July 2021. My firmware is up-to-date with version 1.4.10.8. I do not have any special port forwarding or access control configured. This router does not support QoS configuration.
After initial setup, I get 350 - 500Mbps directly from the router over Xfinity that is provisioned for 400 Mbps. Within hours, the rate drops to 120 - 150 Mbps. This is consistent and repeatable.
I enabled Airtime Fairness. Nothing improved.
If I do a reboot, nothing is improved. This is consistent and repeatable.
If I do a hard factory reset, speed is temporarily restored in full. This is consistent and repeatable.
If I restore a backed-up configuration and then restore/overwrite + reboot, speed is temporarily restored in full. This is consistent and repeatable.
This router needs better firmware is all I can figure. I am not the only customer with this issue in this forum. I hope Netgear reads this post and will respond.
