Does Cable slow down at night?

Hello, earlier I talked to a rep from Windstream to see if they had a cheaper internet plan. On Spectrum, I currently have the 120 Mbps plan and the Windstream plan offers 75 Mbps, for 40$/month, which is well below even what we used to pay for 60 Mbps on Spectrum. Anyways, the rep told me that the Windstream speed would stay at a constant 75 Mbps with a direct internet line coming into our house ,whereas with Spectrum, our neighborhood shares a line and that is why speeds slow down at night when everyone is using the internet. Is this true? I don't ever notice our speeds dipping down, they are always at 120 Mbps, and for that reason we'll be most likely keeping spectrum, but do neighborhoods share a cable line? Thanks, Josh.

There is no 120 meg plan for a start

there is a 60/6 and 100/10.. which do you have?

Next, post the modems signal level and error log pages and if you're using TWC's speedtest tool and an ethernet connection to measure speed and what does it tell you?

Sorry, I meant the 100/10 plan, on ethernet, and even WiFi (i have tested on both) I still get around 120 Mbps for some reason, where can I find the modem's signal level? I have a Netgear modem-router combo that I bought from Best Buy, would I find it on the router login page?

Should be a modem upstream/downstream signal level tab when you log into it...

But a couple years ago, If this is an old modem,

Some had a firmware issue with the Network Time Server....

Is it turned on and set to the correct time zone?

You get 120 Mbps on a 100 plan because Spectrum has overprovisioned you a bit. I have the 100/10 plan and routinely get 117/12. 

 

Your original question of whether or not cable internet is shared within a neighborhood...yes it is. All ISPs use shared bandwidth, even fiber. Congestion generally occur at night because that's when the vast majority of people come home from work and kids come home from school and all start using the internet.

Thank you for the information, so it looks like the Windstream rep was lying to me about the "direct line" lol. As for the up and downstream signals, as of 11:00 AM, here they are:

Re: Does Cable slow down at night?

You have something that's corroded or loose allowing ingress from local tv ch 27.

It's causing some of the slowdown

Totally forgot about posting the signals at 6 pm, sorry, thank you for letting me know about the corroded cables though! Should I contact a Spectrum rep and ask to replace the cable or is it not that big of a deal? Thanks!

Re: Does Cable slow down at night?

You are getting more than you are paying for so unlikely they will do much.  If (when) your speeds drop way down or your modem starts rebooting at random times, then call and tell them that is happening.  You can see your Ch 2 on your modem is messed up (reason for MsRaye's comment) and they will hook up to your line and see the issues and track it down (or just start replacing connectors and maybe cables).

Re: Does Cable slow down at night?

Sorry for reviving an old thread, I also noticed lately that all my cable boxes will just glitch out on certain channels, but I think I found the problem with my signals. We had our front porch torn down and hired people to build a new one, and they cut the cable coming into our house a little, and now that I remember, ever since we got our new porch , our incoming signal has been terrible
