Started the dreaded blink (internet light only) last Friday. At first it only went out at night after I shut down or put the computer to sleep. It wouldn't come back until early afternoon. Gradually it was out longer and longer and now it's gone completely. Speeds plummet to triple digits (usual 6900/480) and take awhile to come back to anything useful. RCA modem fairly new since last time I had outage problems. Strangely though this time my Ethernet link is still green light (Usually it goes red in my network status), but I get different IP address. It's says I'm still linked to the internet but there's nothing on the other end. They're doing a lot of construction around here so I don't know if it's because they're rearranging stuff again or not. Have done all the usually troubleshooting, reboot, wire check, etc. Sometimes it resolves itself sooner or later, but this is ridiculous. RR net stat is red all over as usual. Was hoping this was not unique issue. I've read folks all around the country are having similar problems. Any thoughts? Or is this just standard TWC foolishness? ]]> http://www.dslreports.com/forum/remark,20741551 Fri, 04 Jul 2008 12:52:07 EDT http://www.dslreports.com/forum/remark,20721466 anon : I have RoadRunner internet service from TWC in Manhattan. My service is very erratic. when it is working, I reliably get over 6M download speed, but the problem is that it cuts out 8-10 times a day for 2-5 minutes at a time. Basically, if it hasn't been used in a while, when you first start using it again, it works for about 30 seconds and then goes down for a few minutes. I know the address of the internal web server in the RCA cable modem TWC supplied, and I have printed out the error logs, which all say that the modem didn't receive an expected ranging response. If I call TWC/RoadRunner CS, they can't really help me because whenever I call, the system is working, and if the system is working, they take the position that nothing is wrong. Even if I call when the system first goes down, it almost always comes back up before I get connected to a CS representative. I did insist that they send a technician to my house because I was hoping that he would at least look at my error logs, but he didn't have a clue what they meant. He did swap the modem for a new one and checked that I had proper signal levels. But that only fixed the problem for about two weeks. The problem is that the issue is clearly a network issue, not an infrastructure issue. And most probably a provisioning issue, IMO. Does anyone know how one can possibly talk to a network tech at TWC/RR to look at my logs and hopefully fix the problem?

FYI: My modem has five lights, reading from Left to Right: Message, Cable Activity, Cable Link, PC Link and Internet. During normal activity, the Message light is always out, Cable Activity flickers, Cable Link is continuously lit, PC Link flickers and Internet is continuously lit. When the connection goes out, Message, Cable Activity and Cable Link are all out and PC Link and Internet are flashing (not flickering (which indicates activity), but flashing with a steady rhythm).

The error logs all have one of four error messages in them, as follows:
