Expat_Trav posted : Spent an half hour on with Technical Support (sic) yesterday evening who could not give me a straight answer as to what the cause of the problem was, is and continues to be.

It was claimed that a ticket had been raised with a higher level teir to investigate but could not get a ticket. when asked as to what the SLA ( service level agreement) i was told that he hadnt raised the ticket yet and couldnt give me a number.

i am now going to spend my 5th consecutive night on the phone to be fed more BS.

No one is helping, no one, is telling me the reason why my $65 dollar a month service is poor, no one is managing my expectations and because I am an informed customer I am quickly learning that simply no one simply cares.

Expat_Trav posted : For what its worth, I have seen a few occasions before the Saturday outage that the DS lamp was amber instead of the usual Green. rebooting the CM came back ok.
Since the Saturday outage watching the cable modem boot in the following sequence.

Power - Solid
DS - Flashing Green
DS - Solid Green
US - Flashing Green
US - Solid Green
Online - Flashing Green.
Online & DS STATIC ORANGE - for 1-2 seconds
DS - Solid Green
Online - Solid Green

Link light begins to flash. And the modem comes online.

This is NOT a local issue but what the cable modem is getting from the head end.

Expat_Trav posted : Yes I do have a router in the mix, a Decent TP-Link model that has been bullet proof since I purchased it last year. I also have an Apple AP that is hanging off the end of my gigabit local network to extend my wireless N coverage in the house.

Of course I have rebooted / Reset the router as well as held the Cable modem reset in for a good 30 seconds ( so its reset 2-3 times ) more times than I can shake a stick at.

Again Daytime speeds are OK just since the outage that we had in my area on Saturday my afternoon / evening speeds are cripplingly bad

I am currently replying to this thread by RDC from my work this is currently what my CM is showing me.

Also, if you are not subscribing to one of the higher tiers (50mb+) you won't bond more than one channel.

My dad's on 15/1 and he's bonding four downstream channels. I would hope that's not the case elsewhere.

do you have a router in the mix? if so try to hook the modem directly to your computer, power cycle the modem and try again. Also, if you are not subscribing to one of the higher tiers (50mb+) you won't bond more than one channel.

my amazon prime has been loading for 5 minutes, netflix tells me the servers down.

3 minutes and counting for the speediest.net website to even load...

WhatHappened posted : I reported the same issue of losing Chanel Bonding in Sept and it still hasn't been resolved. I am getting no benefit from a DOCSIS 3.0 modem at this point. I also of coarse get slow speed during any peak hours without the bonding to help out. My signal levels and SNR are great, so has to be a head-end issue.

I PM'd Chad but of coarse nothing was wrong that he could see and only could setup a Tech Visit. A home tech visit will do nothing as it is either a policy change to not bond certain service levels, some joker at the head-end who has messed with the settings or an equipment failure or they moved equipment to another area (this has happened in the past when a larger area had a failure and they took our local QAM up-steam card and replaced it with a QPSK (slower) model.)

Expat_Trav posted : Although the report from chad said that there was no further issues several calls to mediacom technical support has confirmed the local concentrator in my area is crippled if not out of action.

There is no eta and no suggestion as to the exact issue. And to date an engineer has been out to the fault. i am now at the point that my service is below a single megabit, thats less than a tenth of the bandwidth I should have.

This appears to be the beginnings of the same crap I had to endure all last winter.

Quickly running the math I am paying $800 dollars + a year. There has to be at least a thousand customers in my small town alone which equals between $500,00.00 and $750,000.00 per annum.

Mediacom must be raking in millions per year in indiana alone yet no one can be bothered to lift a finger to resolve an outstanding technical issue.

Please explain if there is no issue why I cannot watch Netflix with my family, why my kids cannot access the internet to help with their school work and why i cannot reward (after completing their homework) my kids with some games console time as they cannot get on to xbox live or playstation network.
