Asus RT-AX88U Router will not maintain gigabit speed
I have an Asus RT-AX88U router updated with the latest manufacturer firmware and an Arris SB8200 modem.
I have the gibabit internet package and I know both devices are compatible.
I would like to know if there are some settings I am missing or if I need to do a factory reset as my gigabit speeds only last for a short period of time then are reduced to a fraction of their original speed. Upon power cycling the router the speeds recover but, again only for a short period of time
Power cycling the router alone restores the speeds as well making me think it is not a modem issue.
On a fresh power cycling of both devices I show 6-700 Mbps downloads and 42 ish Mbps uploads.
However after several hours the download speed upon re testing is around 5 Mbps and 13 ish Mbps uploads.
These speeds were determined at the router via the internal speed testing app powered by Ookla.
QoS is off , Guest network is off, using a CAT6 cable
@EG I have seen some of your comments and was hoping you could possibly help me troubleshoot this.
