Answer these 6 questions first, then answer any of the following questions that are specific to your issue:
1) Your location: Burbank, Illinois
2) A description of the problem: Every 1-2 Minutes the internet will stop working for about 10-15 seconds.
3) Occurrence: The issue is intermittent. On the weekends it will occur constantly, but during the weekdays the problem seems to go away around 9pm and return around 7am.
4) Modem Stats: My modem is a Motorola SB5120 the Firmware version is SB5120-2.19.0.10-SCM01-NOSH
5) Hardware Setup: I've previously used a router, but I have removed it from the equation and I am now directly connected but the problem still exists.
6) Anti-Virus and Firewall: McAfee VirusScan Enterprise Ver. 8.0.0
If you have an issue with slow speed:
# Post a speed test:
# Post a tweak test: Here's My Tweak Test
I don't have an issue with slow speeds, but I figured I'd post these statistics anyway, as they may help.
If you have an issue with an intermittent connection or no connection:
# What indicator lights does the modem have and the current status of each: When the internet stops working for the 10-15 seconds the activity light will stop blinking, even when there is a constant stream of data flowing like streaming music, video, or an online game.
# Post signal levels:
Signal to Noise Ratio: 32dB
Downstream Power Level: 5dB
Upstream Power Level: 49dBmV
# Give a description of the cable & splitters configuration in your home leading to the modem: The problem was occurring even when there was no splitter, but recently a technician came out and told me that my power levels were to high, so he placed a -7.5dB splitter on my line. So the drop from the pole, comes to the box outside my house, where he installed another filter, that another technician came out and removed recently, which brought my power levels up slightly. The only current splitter is inside the house which is the -7.5dB splitter. Either way, the problem occurred with and without the splitters.
If you have issues with packet loss, latency, or routing:
# PingPlotter:
During Internet Connectivity:
During An Intermittent Spike:
The above graphs which are on the bottom of each picture are over 10 minutes of data. The red bars are obviously when I am disconnected and as you can see they don't last very long. To a normal web user this is unnoticeable. However, to a hardcore gamer such as myself, this is very annoying and becoming increasingly so.
# Smokeping: My Smokeping
# Line Test: My Line Test
# Post any additional information that may help in resolving your issue: This issue is ongoing, nonstop for about 3 months now. I have had 11 technicians out here, and my account has been credited with $160, so Comcast knows the issue is there, but still cannot resolve it. I have had my Modem(leased) replaced twice, I have replaced the ethernet from my modem to my computer, as well as my NIC. The drop to my house has been replaced, as well as all of the Coax Cable, and filters have been replaced on the pole as well. Splitters have been installed and uninstalled numerous times. I canceled my internet for about 1 week, until I received a call that a major issue has been resolved in my area. After hearing this I was excited to get the internet back up and running, just to find that the problem still exists. Nothing has been replaced and no technicians have been out since I have had the internet reinstalled. I am currently scheduled to speak with the Comcast Executive in my area, but I was just curious to see if anyone knows what's going on or if anyone can help me. Comcast insists the problem is not with their nodes, but with my Hardware. The technicians keep re-doing and un-doing each others work. I am really confused at this point, and Comcast HSI is the only Cable ISP in my area and I don't have a phone line to switch to DSL.
My modem log keeps showing the same 2 messages over and over again, I don't know if this is related though. They are as follows:
# IGMP: ERROR - Group address 0.0.0.2 is not a legal multicast
# No Ranging Response received - T3 time-out
Any help that can be provided is greatly appreciated.
Thank you,

| You too huh? Damn, thought I was going crazy here. I am in Valparaiso Indiana. Head comes out of Chicago then to Hammond then finally to me. Everything you describe sounds like me except for the slow speeds. When it's up, my speeds are fine and I do have some PL, on the 3,4,5 hops but nothing over 10% usually.
I don't know what to do. I have had 7 techs out. Todays replaced everything from the drop in. Arris Cable modem has been replaced 2x 1st was a Motorola VOIP. yet tonight around 7:45 central it went down again to a powercycle and back up. | |
