sean67854, I will be happy to look into the service issues you are having. Can you send me an IM with your account or phone number?

I have been experiencing the same issue in East Moline, Il. They didn't see anything wrong so they are sending someone out in a week...so I have to deal with it until then.

I will be happy to help you with this issue. Can you IM me your account or phone number?

reply to sean67854
This has been happening for me a lot again - just had one in fact.

Same issue here. Internet is down, modem is in continuous reboot loop.

danawhitaker and jhigh, send me an IM with your account or phone number and I will look into the issues you are having.

Exact same problem here in Hazel Green, WI. It's been going on for well over a month now. Tech's been out twice to confirm that it's not an issue with my house or modem. I've been going back & forth with Twitter support the entire time. Every day, they use the same canned response about how they're doing everything they can, etc, yet fail to provide any actual evidence that any progress is being made, or that it's even being looked into!

To be blunt, I'm about fed up with this and am going to cancel the service if it's not dealt with soon.

I assure you, we are doing everything we can to get this issue resolved for you. I have replied to you via IM.

For me it seems like whenever I try to pull more time sensitive bandwidth, like to watch a video or when starting a download, or when I start a web conference it will drop for 30 seconds or so. It also drops at other times too.

Over the past few weeks, I have yet to watch an on demand movie or play a game online without an interruption.

That's usually when I see it too. Otherwise it seems to be fairly random, yet quite common throughout the day.

So just to update everyone, they're blaming the issue now on the wiring in my home, and have scheduled another tech on-site (3rd time) to replace the "older standard" of RG59 cable. Funny thing is, Mediacom rewired my entire house just over a year ago. Everything is brand new.

I don't buy it. It seems like no one really understands the issue and are just guessing at a solution. Not impressed.

I wish the rest of you all the luck in the world. This is becoming laughable.

Mediacom installed the cable to my modem themselves. It's an unbroken line (well, there might be a grounding block) from the cable riser in the corner of my yard, buried along my property line. It then comes in through the wall of my garage right to my modem.

FYI, I can see in my modem logs that when I have a drop event, it tries to reset itself. I wonder if the issue has to do with the new usage metering. I've been having this issue for a few months now, but I chalked it up to my wireless connection until I recently moved my PC to a wired connection and I'm still getting the same issue.

The log below shows the activity during my most recent drop event. Which coincidentally happened while I was typing up a response saying I didn't think the issue was with my router. I did not touch my modem at all during the time of the events in this log.

I am not seeing any drops on the modem, but I do see that you have had the modem since at least 9/16/05. I recommend replacing the modem to rule out that it is an equipment issue.

reply to sean67854
I replaced my modem at around 930 this morning and haven't had a drop yet. Keeping my fingers crossed.

I have noticed something like this too. While I am web browsing, I will get no response from requested web pages (basically, like the internet is down) Then I will glance up at my cable modem and notice that some of the connection lights are off / blinking like they are trying to establish a link. After 20 to 60 seconds, the link re-establishes and the everything is working again. It is the Send and Online lights (SB5120) that are out and have to reconnect. The signal levels I see on my modem page are well within the recommended limits. This doesn't happen that often. I can watch full length movies from Netflix with no issues. I have only noticed it when I am browsing websites, but then again I am sitting right there at the computer when I am browsing. I just figured it was Mediacom network issues. I think I will have to pay more attention the next time it happens.

Well, now it appears as though my upload is capped at 1meg. In the past when I've had good results, I've gotten all the way up to 2.15up. Now when I test in the early evening, 1am, 11am, it caps at .97.

This only started happening with the new modem?

I believe so. I think I would have noticed it in my testing before, just as I noticed it now.
