They often say everything looks okay. I can recall one conversation where the tech said he was talking to my modem and there were no problems all the way to it. I replied that it was unplugged in my hand because I had done so to read the serial number to him, so he couldn't be talking to it. Service did get better after that. :) -R> On Thu, Feb 20, 2014 at 12:35 PM, shawn wilson <ag4ve.us () gmail com> wrote:
Thanks. The tech said they looked at signal levels when I called and didn't see anything. I didn't have a baseline at the time (I do now) and assumed they'd see something there if there was something. I do have the Netgear. So I'll keep this in mind when I call them again (assuming it's really not a noise issue) though I'm not sure exactly what happened here or how I can get them to try the same thing?

They swapped out one Netgear modem for another Netgear and the problem continued. The phone techs couldn't see theproblemand kept blaming our equipment. They finally sent out one of the'senior'engineers I had worked with before on other jobs. He managed to get aholdof one of the SMCs from their warehouse. No more issues. -A On Thu, Feb 20, 2014 at 1:08 AM, shawn wilson <ag4ve.us () gmail com>wrote:A while ago I got Comcast's business service. Semi-idle connections are get dropped (I haven't really diagnosed this - I just no that it isn't the client or server but some network in between). However the second and most obvious issue is that intermittently, the service will grind to a halt: --- 8.8.8.8 ping statistics --- 37 packets transmitted, 34 received, 8% packet loss, time 36263ms rtt min/avg/max/mdev = 398.821/5989.160/14407.055/3808.068 ms, pipe 15 After a modem reboot, it goes normal: --- 8.8.8.8 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 23.181/23.920/24.298/0.474 ms This seems to happen about once or twice a day. I can't attribute it to any type of traffic or number of connections. All of the rest of the network equipment is the same and the behavior persists when a computer is plugged directly into the modem. I called Comcast and they said they didn't see anything even when I was experiencing ridiculous ping times. I tend to think it's an issue with the 'modem' but I'm not sure what the issue might be or how to reproduce it when asked to if I tell them to look at it.
