CM2000 Slow Download/Upload Speeds
I recently purchased a CM2000 to replace the equipment that I was leasing from Suddenlink. The modem that they provided was testing at 900Mbps down/40Mbps up but this Nighthawk is only testing at 21....
Do you have a screen snip of the cable connections page?
are you connecting through a router or directly to the modem?
This is the first time correctables/uncorrectables has been above 0. I just tried the other modem again as well and it is still pulling top speeds while this netgear is only pulling 20-22Mbps down.
You have a lot of errors in the line.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.Why would this modem have issues with the line when the other one does not? Is it just more touchy?
No idea what your other modem is but it could be a couple things.
1. the other once could be a docsis 3.0 device and the issue is on the 3.1 channels
2. it could be the other modem is starting at a difference frequency and the issues are only on a small section of frequencies. That does happen
