Not getting full gigabit speeds with Netgear Nighthawk AX5400
Upgraded to Xfinity 1000 Mbps/35 Mbps plan recently. Had comcast guy fix the connection and could reach 900 Mbps from the modem (Arris T25 with Docsis 3.1) directly. Old router from Linksys ES850...
Have you tried testing directly off the modem yourself?
Another thing to try is factory reset the router and then set it up with default settings and speed test it. If it hits full speed, then try making changes.
What website are you uing for testing?
Make sure to test over a hardwired connection.
Thanks for the reply.
I used the same PC connected to modem to get the speed, speedtest.xfinity.com, and with hardwired connection.
The netgear router is a new installation, I only added some port forwarding.
And what speed do you get hardwired directly into modem?
I still recommend the factory reset/reinstall (not from backup).Reason why is the RAX devices were released before the AX spec was even finalized. So they recieved quite significant firmware updates. This makes them respond very favorably to a full factory reset after the firmware changes. And if it was new and auto-updated, it might help.
so try the full factory reset and then test with by instalilng with the default configuration.
Direct from modem speed is around 900 Mbps, same PC and same wired connection.
I did upgrade FW when I installed the new netgear router. Will try factory reset tonight.
Thanks,
