Help with "weak" coaxial cable questions?

[cctaylor88]

Paying for 100 down speeds from my ISP. I'm able to obtain those speeds before I leave work at 5am. Come 5p-8p at night I'm literally getting speeds of 1-5down. So my initial thought is traffic congestion in the neighbor hood etc but those speeds are insanely slow no?

I was told by the last ISP tech that visited that my coaxial cables are the problem and they need to be replaced on my end. Find that incredibly hard to believe. My question is. IF a coaxial is to blame somehow (my home was built in 1996 btw) wouldn't it be incapable of allowing me to reach 100+ down at any point? I mean if its so old/broken etc why then am I getting perfect speeds at various times??

If you can regularly demonstrate 80-100mbps during certain off-peak times of day, and sub 10mbps during prime-time hours, that's pretty clearly a case of congestion, either locally at your neighborhood level, or even further afield on your ISPs network, though my guess would be something very local.

Sounds like he's over-due for a "Node split".

Also helpful would be a mention of WHICH CableModem he has. More channels means less congestion during peak hours. If he's still on an older 4x4 DOCSIS 3.0 modem, or worse, that could be the reason too. Time to upgrade!

But if he's on a 16x8 or better, and still seeing that congestion during Prime Time usage, then yeah, his ISP needs a node split.
