I have been having some connectivity issue with my Motorola SB5101 modem. Fortunately it happens mostly during the summer, where for some reason the modem would restart itself and the light would be stop and blinks on the "Send" light. The "Power" and "Receive" lights are the only two lights that stays fully illuminated. However when it hits down to the "Send" light it gets stuck there and stays there continuously blinking until it restarts itself once again. The rest of the lights underneath it (the "Online" & "Activity" lights) never gets a chance to turn on. This occurrence is very spontaneous, where it very unpredictable which makes it difficult to call for a service repairman when the appointment won't be til the next day. I have call Charter Communications multiple times where they seem to be unable to connect to the modem. It been working fine mostly throughout the year, but when it hits the summer abnormality happens, and it have been happening for many summers now. I have tried turning everything off for 30 seconds and sometimes it works and others doesn't. It just seems it wants to work again only when it wants to.

Should I tell the repairman when he arrives that it's been working terribly in the past few summers, but works fine during the when school's in session? How is he going to diagnose the issue if it's only visible when he's not there?

If this helps I have checked the router's page and this is the information I have received:

[FONT=Arial,Helvetica]Downstream[/FONT] [FONT=Arial,Helvetica]Value[/FONT] Frequency643750000 Hz Signal To Noise Ratio35.9 dB Power Level-8.0 dBmV

Unfortunately I would provide you my logs but it was cleared after when I hit "Reset to Factory Defaults". However I do remember it saying a lot of T3 Time Outs.

If you go to DSLReports they have a forum just for charter subscribers where you can talk to a tech one on one. They can access your modems log and look and see if they see a problem and then send out the appropriate techs. Here's a link to the forum, you'll just have to register first. - https://secure.dslreports.com/forum/charterdirect

I frequently post there when I have similar issues and they are good about getting a tech out quickly. If you go through your local office they don't always send out someone with the experience necessary to diagnose the problem. They usually just send out the first person available in your area.

You're welcome. I have lots of experience dealing with Charter unfortunately.

Yeah splendid job Xeno1 I'll give it a try

When I was getting a whole lot of T3 timeouts it was being caused by expansion/contractions issues in my dropdown and as soon as they replaced it it was all good again. Since you say it happens more in the summer that could definitely be the problem.

Sorry I am late but a realized a few months ago it was actually a faulty splitter, now everything seems to work smoothly with a new one.

Thanks for letting us know DangerousPirate.
