Re: [Connectivity] Chicago area uplink interruptions? Well, I think I solved the problem. I replaced my Motorola SB5120 with an SB5101 and my HSI connection is working much better. Virtually no dropped pings (less than 1%) and absolutely no consecutive dropped pings, which occurred before during my uplink outages. I also did a 45 minute test (listening to my clock radio on a call from my VT line to my cell phone) and have made a few more calls all with absolutely no drop outs. I wasn't able to get the Comcast tech support person to tell me what my uplink SNR was with the old or new modem... they didn't know what I was talking about and said everything "looked fine". But I *did* see my downlink SNR go from ~35 to ~41, not that I was really having any downlink issues, but the 6dB increase certainly doesn't hurt. I suspect my uplink SNR may have improved too, but I guess I'll never know. In any case, it really seems there was something wrong with that SB5120. |

| While I'm not an expert on signals, your story brings to mind the problem with the SB5120s. They were more vulnerable to line noise then the 5100, 5101 and 5102. It has to do with the differences between chipsets used in the modems.
»Comcast High Speed Internet FAQ »What are the differences between the Motorola SB5100, SB5101 & SB5120?
The 5101 you have now is more capable of taking less then optimal signals vs the 5120.
Good luck with your setup. |
