Slow throughput on CM1200
I moved to a new house and since moving in I've struggled with the speed of the internet. I've called the ISP out 4 times now, they run their test, say everything is OK and then blame the modem. I p...
Have you tried a different device?
Maybe the sparklight guy was right but tough to know if you're only tested 1 device.
And how are you testing? (site, server, etc)
What arris modem did you have? (still have it?)
Did sparklight try their own modem?
Yes I got the CM1200 because the Arris was the Sparklight provided modem, and was still having this issue. I had called twice and had two techs come out and they all said the same thing. I had to send the Arris modem back so I don't have it anymore. I only have 1 laptop that has a 1GB NIC. I'm testing using the Ookla speedtest site.
when 2 different modems from different manufacturers are having the same issue, it tends not to be the modem. The odds of 2 different devices being bad is pretty low.
I'd see if you can borrow another laptop to test and if its still slow then you might have to do some creative solutions.
What I mean by that is rent one of their modems from a month. If its not getting full speed, then they can't blame the equipment anymore. Its makes it purely on them to fix it. I've had to do this before when an ISP wouldn't believe it wasn't my equipment.
And worst case scenario, it is the modem and if renting one gives you full speeds, then you have proof and can open and RMA with netgear.
Thanks for confirming what I was already thinking. It likely is an issue with thier connection, but the only way to prove it to them is to get their modem back and confirm the same issue. Thanks, I guess I'll have to reach out to Sparklight and request a modem again. I'll update this post as I get more details.
FYI, I've had a CM1100 and CM1200 on Sparklight as well. Have not seen any issues where I'm located on there services.
