XR500 ipv4 vs ipv6 speed differences
I feel bad putting this here without knowing more but I recently got a new config from my ISP for a 900/35mbs line (from 400/35). Direct line tests for around 500 (on speedtest.net) and ISP still thi...

Just wanted to follow up saying that I managed to resolve the issue by rebooting both the cable modem and the router in sequence leaving the MAC at the PCs. I strongly suspect that the XR500 router was not at fault for the issue but rather that for some reason the ISP/modem capped ipv4 traffic until the reboot.
I am now running with QoS and ipv6 fully enabled without any issues and get equivalent speed tests over both ipv4 and ipv6.

Hi there - are you on an IPv6 connection then or are you on IPv4? IPv6 can often cause headaches for routers, so I would recommend disabling it in >Settings >Advanced and see if that solves your lower speeds.
Also, are you connecting using PPPoE? If so, I recommend you put PPPoE on your modem instead of the router
With QoS disabled, you should easily be hitting 900mbps without any other changes required. Un

When I turn off ipv6 all my speedtests drop to below 120. I'm attaching a retest with the microsoft network speed test after I disabled ipv6 completely just now. It also shows the previous test with ipv6 enabled. My problem appears to be that all ipv4 performance is degraded and the only way I can even see good bandwidth is with ipv6.

Not using PPPoE.

Ok, try disabling IPv6 and see if that improves things.

This is a $300 router and it has troubles with IPv6?
LOL! Can you guys be more transparent what this router CAN do and not what IT CAN'T DO? The list sure seems short for what it can do.
