| [VA] Internet connectivity issues
For all those who know more than me:
Last weekend, I had issues with my cable modem. Anywhere from every 10 minutes to every 45 or so, my cable modem would lose signal, then go through a "reset", then work fine again.
Two calls to Cox Cable customer support were unable to resolve this (they wanted me to wait it out, then possibly send out a tech at MY EXPENSE).
I waited, and on Monday, things were fine again. No reboots, no connectivity loss.
Yesterday evening, the issues started again. I thought it might have been because of the modem, so I bought a new one (Linksys CM100). Called Cox, gave them my MAC address, got things going.
Although I have noticed a definite speed increase (yay new hardware!), the connectivity issues have remained, and I've already had three signal drops since I started using the new modem.
Here are the modem logs (since connecting the new modem):

Anyone have an idea as to what else I should try to fix the issue? All my cables are attached properly and all that jazz, or I wouldn't be on here now. I am tempted to just wait it out and see if things correct themselves tomorrow, just like last week. At the same time, I don't want to experience another frustrating weekend of spotty internet connection if something else can be done. |

| Well signal levels look ok to me, but reading that modem log with them T3 timeouts.. its ok to have one or so a day but it looks like you are having alot in one day which means there is a problem somewhere.
I would get a tech to your place asap, Btw if you don't have it already call Cox's CS, and tell them you want to add there insurance plan which is like $3 a month, and it will cover the tech coming out. Because without that insurance plan its $50 per tech visit. |

Alexandria, VA | Is it really necessary to have a tech come out when, after I had this issue last weekend, things resolved themselves for almost a week before the issues started up again? |

So, after experiencing this problem for three weekends out of four (every time, the problem resolved itself, and I noticed it was both my TV AND internet signals having issues), I had a tech come out to look at the issue (and yes, the problem had resolved itself before he came out).
He seemed to think there was an ingress issue somewhere, but he wasn't really able to communicate where it was, or track it down. He tightened all my cables, seemed to think that should correct the issue, and left.
Lo and behold, this morning around 1030 AM, the problem returned, and lasted for at least the 90 minutes I was home before I left for work.
Short of calling Cox again when I get home and having them send another tech out, are there any suggestions as to what I can do to fix the problem? |

| said by pr0ner  :Short of calling Cox again when I get home and having them send another tech out, are there any suggestions as to what I can do to fix the problem? if the issue is truly ingress, then no. the issue is that someone is backfeeding noise into the cable plant causing you to lose synch with the modem (because the cmts and your modem can't communicate over the noise). because the problem is intermittant (all times of day and all days of the week), there is someone doing something causing that noise. its hard to track down as he has to be out there when its occuring and then start "listening" to the plant to see where the noise is coming from. its a difficult issue to troubleshoot.
i would work online with the tech's on this forum - especially the ones that are local to you - and see if you can get a game plan down.
