Internet Support / super slow speed
« on: September 21, 2013, 10:05:15 AM »
Experiencing super slow speeds since about 945 this morning. Speedtest.net showing 0.6 Mbps download. Rebooted modem and router and now can't even load up speed test. Internet connection is up though as can ping our Mediacom node and Mediacom DNS servers. Help please!

Internet Support / internet out in carbondale
« on: July 13, 2013, 08:45:36 AM »
Woke up this morning to no internet. My router shows it is getting an IP from Mediacom and I can ping the Mediacom gateway. So this means the problem is outside of my home. Outage?

Internet Support / Internet dropping frequently.

Let me start by saying I am supposed to have a tech at my apartment tomorrow to check on things but am absolutely not expecting them to find any problems here or in my complex.  There are a couple of reasons for that.

1) I have had Mediacom in a couple of different towns over the last 5 years and over that time have learned that the service I can expect from a field technician and the phone tech support is very spotty, and unfortunately is almost always on the poor side.  Usually when a tech is out for problems they replace our equipment, regardless of how many times it has been replaced in the past for the same trouble.  Having worked for an ISP in tech support and NOC work for many years (not Mediacom) I understand that this is what is normally done as it almost always fixes the issue, at least long enough to calm the customer for a few days and let them pay another bill.  The problem is it almost never is the solution for a chronic problem.  So that being said, reason 2....

2) The apartment complex that I live in just was made active for Mediacom services during the third week of October 2011.  As part of this process, Mediacom techs (contractors) installed brand new coax in EVERY unit in the complex.  In addition, due to the size of the complex we have our own dedicated node (going off of the word of the contractor in this case).  So with new network equipment and lines this only leaves me a few likely solutions to my problem. It could be my modem, it could be a coincidentally bad line, a bad port on the node, or most likely a problem between the node and the CO.

During the last several weeks I have gone through several troubleshooting steps on my own and have been able to rule out any of my own equipment and have replaced the modem with one of a different model and still am experiencing the same difficulties. 

With both modems, the event log showed a vast wasteland of error messages whenever the internet would drop.  Here is a copy of the eventlog currently:

When the signal does drop I have seen my SNR get as low as 32 dB... definitely not optimum but not hypercritical either. 

With the previous modem, which was the netgear cgd24g, in addition to the above mentioned errors, I would also receive the following message: "Network Access: Denied".  This would appear on the Gateway status page when logged in with superuser access (MSO/changeme).  I received a similar message on the Connection page with the line "Connectivity State, In Progress, Not allowed."

Now, since the line between my apartment and the node is brand new, it's possible, though HIGHLY unlikely that line is the problem.  The same goes for any issues at the node.  Having worked in an ISP long enough I understand that they could be part of the problem, although you and I both know that is very unlikely, but I'll entertain the option long enough for the tech to replace the cable and change my port at the node.

This leaves the most likely scenario as a configuration error at the CO, or possible a problem with an AMP on a mainline somewhere, although I really hope mediacom is at least running fiber to their nodes...

So with all this being said, I would really like to give the Mediacom forum moderators a chance as I have honestly heard good feedback regarding the service on here from people I know have had very similar experiences to me with the field techs and over the phone techs.  The over the phone techs that I have spoken to in recent days were not even aware you could log into the modems I have had (192.168.0.1 for the netgear and 192.168.100.1 for the RCA/Thompson).... let alone what any of the messages in the error logs meant.

So, Mediacom Forums, prove me wrong. Show me that Mediacom actually has their customer's best interest in mind and fix my issues permanently, not just long enough for me to pay another bill.
