The long and short of it is since moving into this apartment from another within the same complex, speed issues have been intermittent but constant.
Speeds will drop down to near nothing, sometimes ping times are over 10 seconds per packet, and can last 10-15 minutes, or even longer.
Technicians have come out and stated there is no problems at all. They plug in their machine and can run ping tests and speed tests with no issues. As I state each time, it's an intermittant issue.
They claim they've tested outside and that there's no issues either.
The last person said that they'd have a ?MDU? person contact me about running a new wire - no cost to me - but that was about 4 days ago and I have not heard anything. They also did state that they were pretty sure that there was no problem there, and it wouldn't have any impact on anything.
This is getting old, paying for service for something that does not work at all.

You have severe broadcast TV ingress from local tv channel 41 and many more.
It appears TWC is unwilling to repair or admit there's a problem, or the building owner won't pay to repair it. They will blame it on the modem you own and it is not a modem issue
Due to the interference and MANY BAD CHANNELS, the modem is being forced to acceot 133+ mHz of bandwidth, well beyond ut's spec'd 96 mHz range, Many of the skipped channelsa have serious ingress on them adding to the issue as they affect the adjacent channelas decode response time
This needs a competent tech out. If none contact your states BBB, attorney general and cable TV commission.
copy and paste the signal page so I can disect it here...
imgur doesn't cut it, lol.
Modem should not be skipping channels and on both 507 and 633 which are outside the designed b/w of 96 mHz.
s/n on 633 is out of spec compared to the other 7 ch's
correcteds/ uncorrecteds are a lot higher.
To see if you have an ingress issue:
Do you have a 70 cm handheld? Punch in 445.250 and see if you hear a carrier near cable connections or near the end of one disconnected from the modem. ALL ingress points also egress 54-900 mHz cable, , the ALC pilot is easy to detect at 445.250. It's not tightly Xtal controlled and in some areas you'll hear hetrodyne from 2-3 seperate nodes.
Some leaks are within FCC specs many are not, especially if you can hear them 500' away.
on some systems they intermittently turn on a nother leak detector in the 130 mHz area but not all. I've found 1 out of 5 aboveground cable drops are bad here in NEO... and 1 in 10-20 underground ones
Completely understand :-) Here's to hoping it's still showing the same signs..

There is a loose or Intermittent shield somewhere, the s/n on 633 is back up to normal. that's TV ch 41. what's your zip? look up actual tv @ www.tvfool.com
I'll bet a bunch of the skipped ones are local tv in your area as well.
A lot of people including TWC don't have a clue how qam works, there aren't individual channels or receivers in the modem/ cable boxes and DSP processes the agregate bandwidth. If there are missing channels, not a big issue, but noisy/ severe ingressed ones affect the entire ALC levelling. The channels al must be within 3 db of another for high speeds. and levels can't change.
You need to find the leak and fix it.
