fuzzy clam Posted October 25, 2015 Share Posted October 25, 2015 Hope you get your ISP issue resolved,went thru one myself not to long ago. Ask to get a tier 3 tech or a line supervisor to investigate the problem and compile some data for they to look at. Link to comment Share on other sites More sharing options...

Dillinger Posted November 4, 2015 Share Posted November 4, 2015 Coming in late on the discussion, so I apologize if some of this has been covered, but the OP asked me to stop by and review. I think there might have been some confusion on the RJ11 line, which Zennon was talking about, versus the RG11 line that the OP asked Comcast about. I don't know about RJ11, but if Zennon recommends it, it's top shelf and should be trusted. RG11 is a larger density core cable that is used in CATV applications to overcome line loss due to attenuation. There is no reason to ever put RG11 CATV line in your house, on your house or in your walls. It would be equivalent of taking an armored MRAP to the corner Gas-n-Sip store for eggs and milk. Looking at the numbers, your Signal to Noise ratio is pretty good, which is an inherent problem of a shared broadband path and one of the reasons CATV companies are required to test and report levels like this a couple of times a year. Your power levels, which I assume are at the modem, are well within normal standards. There is a lot more to signal/problem diagnosis in cases like these than just looking at numbers on a screen. The numbers look good, but your initial question is still a bit vague to me. You want to increase your ping and jitter from good to exceptional? To what end? What specifically is happening or not happening that has you going down this path? Because I can outline an entire network for you that is bullet proof and will survive the Zombie Apocalypse, but it's going to cost you hundreds of thousands of dollars. I guess I need to see the root problem, and what you envision being the ultimate solution, because what you are chasing right now is beyond the average homeowners budget.

Zennon Posted November 4, 2015 Share Posted November 4, 2015 We use4 RJ11 here in the UK from the VDSL master socket or ADSL filter to the Modem/Router So I always suggest getting a twisted pair RJ11, this might be different for you guys over the pond, sorry if this has caused any confusion.

We use them over here too Z, but there is an outside cable line called an RG11 also, and I think that is where some of the confusion came in.

tjl118 Posted November 4, 2015 Author Share Posted November 4, 2015 Yo, Thanks for the clear up of the cables. What I ultimately want is for the jitter to minimize (Whats you see in the beginning of this post is everyday stuff and i have been testing everyday at different times and it pretty much never deviates). It is the worst part when playing Call of duty. If you would be willing to assist and have any suggestions I will post whatever info you need. Tyler PS - Dont have thousands of dollars for that network lol Link to comment Share on other sites More sharing options...
Zennon Posted November 4, 2015 Share Posted November 4, 2015 You are at the mercy of your ISP with the jitter, usually down to over subscriptions (to many users / not enough bandwidth leading to contention and congestion. Link to comment Share on other sites More sharing options...
tjl118 Posted November 4, 2015 Author Share Posted November 4, 2015 I have a 100/20 business line. On the network monitor I never use all the connection. Could it be something else? or just that cable internet is not that good when connecting out? Link to comment Share on other sites More sharing options...
Zennon Posted November 4, 2015 Share Posted November 4, 2015 It might not be but it can be other subscribers using the bandwidth that is under provisioned by your ISP that causes jitter. If your line is not in use when you test and you have jitter then it points to this as the biggest probability. Link to comment Share on other sites More sharing options...
