C7000v2 Nighthawk AC1900 Cable Modem Router - Extremely slow upload speed
I'm hoping to get some insight. I have the C7000v2 Nighthawk AC1900 Cable Modem Router. Xfinity service - 1000mbps download/35 mbps upload plan The Nighthawk app under Wifi Analytics ->...
they either need to check the amp, the line again, or the tap. you have a lot of dynamic range window violations which is when power goes out of spec. Plus t3 errors.
I'd remove that amp and see how it does.
I wasn't aware the C7000 could hit 850mbps on comcast. I though it was only spec'd up to 600mbps on comcast.
Comcast requires docsis 3.1 for gigabit lines.
when you say "home testing" do you mean the tech hooked up to the line or you hooked a laptop/pc to it and hit those speeds?
Regardless, you should be able to get faster upload speeds.
do you have a screen snip of the cable connections page and the logs? That helps us to check the line.
So that 850 Mbps number came from the Nighthawk app. Not sure if it was relevant.To be honest, I just upgraded from a 300/10 Mbps plan from Xfinity. I was on the phone with them about why I was only getting around 0.05-0.2 Mbps (at that time) for upload speeds and they wanted to 'save me money' by upgrading to the gigabit plan - 1000/35 Mbps.I didn't need that speed for download, but need the upload to be higher. I figured with a max increase in speed, I might see some increase on the lower end.
I've attached the screenshots for the Cable Screen.
