CAX80 not getting full speed

Aspirant

Jul 19, 2020

Hey All,

Please note when I was using C6300 modem/router I had 100 MBbps plan from xfinity; I was getting 110 Mbps down/5 Mbps up. That tells me its not issue with Xfinity end; problem must be with CAX80's firmware or bootfile cannot handle the Gig speed specs as Xfinity level 2 support suggested ... but I will let experts conclude on this ...

Note: I was on hold for Netgear level 2 today for a little over 2 hours while watching Cheech and Chong's "Up in Smoke " movie. Since no one picked up, after that to release my frustration I went out to mow the lawn after a glass of wine (ok, half a bottle) :)

Hope ya'll having a great sunday but here is my data, let me know if I can provide anything else.

Firmware Version V1.1.0.41
