Sorry, but this just isn't true. There are a lot of things other than over-subscription that can cause slow speeds and packet loss: loose connections, faulty interior wiring, faulty exterior wiring, defective tap, defective amplifier, RF ingress, etc. Almost everyone who complains about slow speeds ends up having one of the problems I listed once they post their modem signals and logs. Over-subscription is a problem but it's definitely not the only problem. People shouldn't give up without properly troubleshooting their issue.
Here is a screenshot of my normal speeds now in Las Vegas. 700+ in the morning and 10 in the evening. Everyday for the past week. This is definitely a problem [at minimum] with the CMTS.
These speed tests are taken hardwired out of the modem (CM100). If I use a completely different modem (Arris SB8200), same result. My neighbor gets the same speeds too (also SB8200). I have new RG6 pulled (by Cox (twice)) to my DMarc where it hits a bonded bullet connector to another brand new piece of RG6 straight to my modem. No wall jacks/attenuators/splitters/taps, nothing. There is nothing left to troubleshoot from the curb to my house. It's all new...and apparently acceptable or I'd never hit 700+
I get what you're saying though and that's all possible scenarios in a lot of cases, but not in my case.
The simple fact is Cox's greed has over subscribed and their nodes can't handle the demand.
I’m running into the same exact problem here in Henderson. Totally fine speeds in the morning and by afternoon we are down to single digits. I thought it was possibly a modem problem. I didn’t have any issues until I upgraded speeds and got their modem (pano). I just ordered a new modem in hopes that would solve the problem but from what you are saying it looks like I’ll run into the same issue. I had 3 techs out here over the past two days and they can see that the node is overrun but why the sudden issue of the single digit speeds? People have been working from home for months. What changed this past week?
I'm at Eastern/215. It's definitely not your equipment. If it was why would you ever get anything above single digits right? My node was split a couple of months ago to relieve congestion, but apparently something else has happened since then in the past week.
