Re: [Speed] intermittent and slow Comcast HSI

Hurray! After 2-3 calls today and 3 service calls in 30 days I have been given to the Comcast Resolution Team. They seem to actually care and are trying to help me.:) And wonder upon wonder they are going to call me (gasp) to check up and see when the problem is fixed.

One of the first techs to visit swapped my cables for the ones he stocks on his truck. There was no change.

Re: [Speed] intermittent and slow Comcast HSI

Well it went badly. I waited through my 2 hour appointment, tech was no show. I called in and they said I missed my call. I pointed out I was on the phone with CSR during the call asking where my tech was! They said very sorry he will be there in next 3 hours. At the end of 3 hours I was told tech call was canceled because I have been referred to tier 2. I was told tier 2 tech was calling in next 3 hours. I waited almost all day for 3 appointments and nothing happened. :(

Tier 2 tech says I have reflectivity issues. Essentially he says every packet I send is partially reflecting back and mixing in with incoming traffic. Anyone ever heard of this before?

He can find out by calling in and asking. To madguy This figure can only be read from their end by them polling the CMTS. It should be 29dB or higher. Make sure that it is indeed the upstream SNR figure that they are giving you because sometimes the CSR's poll the modem by mistake and give you the Downstream figures. You can ask them about the upstream receive power level figure while you are at it. It should fall within the range of -10dB to +10dB.

Yup, (kindof a loose description, as up and down are on different frequentcies) That would be noisy (SNR) probably a line/ AMP/ node problem, which may require different techs to fix. Hopefully tier 2 is arranging for the right people to be sent to your area (you may never see or hear from the line guys, it'll just get fixed)

Re: [Speed] intermittent and slow Comcast HSI

Thanks for the tips. I'll ask about thatand I will ask the tier 2 tech tomorrow seeing as he is supposed to come to my house. Problem is getting worse this past week and we lost phone and internet for 7-8 hours yesterday. They made some repairs so that service is back but both don't work as well as before. My phone sometimes beeps at me for a while before I get a dial tone and call waiting 9 out 10 times goes straight to our voicemail. The internet is losing connection constantly. Worst part is I call comcast and the CSR says everything is fine and I reply "Then why did I have to call you on my cell phone?" If the phone goes out anymore my schoolteacher wife is reasonably going to insist we change service.

Re: [Speed] intermittent and slow Comcast HSI

So tier 2 tech was a really nice guy. He checked things out for a while and up dated my router firmware. Also changed my security settings for wireless around. Things definitely work better but still doesn't seem right. Now that he came out here I don't think I will get anymore help. As much as every test says my connection is good I can't help but notice that stuff works slower on my 16/3 tier than my old companies 3/1 tier service. That hurts.

Re: [Speed] intermittent and slow Comcast HSI

I have the same problem in northern Colorado. My modem signal strengths and S/N noise are well with specs; actually ideal. My 16/2 Mbps connection routinely goes into 3/x Mbsps where x is any random range from .1Mbps to 5Mbps.

Comcast is apparently doing something with their system to "optimize" those systems, like mine, that are less than modern, from what I glean from Customer Service.

Re: [Speed] intermittent and slow Comcast HSI

Well service still slow and dropping out for a few seconds every hour or so. No further attention from Comcast is coming as they consider issue closed. At this point I guess I am just waiting for PHIOS to come to my area lol. So far trying connections at friends houses has given a better speed on everything but dial-up. How does 3/1 dsl beat the pants off 16/2 when it works correctly (supposedly) ? I could show the tier 2 tech that down loads and streams were slow and stumbled ,but nothing that could be measured so it is "fixed". Adelphia why did you leave me? :(

Re: [Speed] intermittent and slow Comcast HSI

So on friday the 13th :o my wife tried to call me at home and it took 3 tries before she could get past voice mail and actually ring our phone. I called Comcast and a tech call was scheduled for monday. On monday the tech said he pulled error codes from every service and that he got almost all codes possible. Two hours later a maintenance worker checked in to tell us that it was a head end problem and he would pass it up the chain. We still haven't heard anything back yet.
