I have an AC1900 router from Buffalo and an Arris Sufboard 6141 and I'm getting around 90megs down. Has anyone experienced this and what do I need to do? Both devices are compatible with the speed I've just signed up for, 200megs down. FWIW I am getting around 11-12 up.
Thanks, Andrew. I did not. Let me clarify.
Comcast > SB6141 > Buffalo AC1900 > AppleTV (Ookla Speedtest).
I have also attempted a speed test from a AC1900 > PC using the Xfinity speed test as well as AC1900 >•) iPhone using the Xfinity speed test.
Will drop off VPN and try my work laptop using the Xfinity speed test.
I just tested a direct connection to the modem and I got over 220mbps down.
Any tips/pointers on how to get the modem up to speed? The current MTU is at 1500 but that's not going to help (AFAIK) as that's for packet fragmentation, IIRC.
