Internet stabiiity test? - Page 2

post #11 of 20
Thread Starter 
Which is good because then I can isolate if it's computer, router, or modem problem. I will try to take pictures tomorrow. Broadband package is their "Turbo" package which is 20 mbps down. Often, I will get 35 mbps down though. Cable internet only from TWC, no TV packages.

It's so I can isolate the problem and have definite proof that it's occurring. Basically, so I can have evidence to show my ISP and get them to fix the problem if it's on their end.

I wish it were the case with all cable providers, and even then down to each technician. It is hard to get a good technician to do his entire job on a trouble call.

Especially when they get there and the services are 'working'.

I know the workings of the CATV network bro. I am a Network Engineer by profession, more specifically for a cable provider. Get me my information. I will help you to know/understand what it is your tech should look for/fix when he comes out.

Any splitters you know of between this box and your modem?

With your signal strength, you must have a wiring issue.

For DOCSIS to be 'possible' on a multi wire dwelling, DOCSIS specifies a minimum of -8dbmv signal strength. ( after all home wiring, measured at the modem, but you have no splitters so its like a straight line )

With that RG11 drop cable I see in your image, resistance is pretty minimal.

With no splitters, you should have either perfect signal ( with minimal at the security box being +10 ) or way too much ( blasting ) at the modem.

noise levels looked okay at the modem, however it is not nearly as accurate as a CATV meter.

There's is just no way you are losing 20-35db through healthy cable/fittings.

At the downstream you'll lose about 5db per 100 feet through RG6, closer to 3.5 on RG11.

Here's what I think the issue may be, Bad directional coupler in the tap, or a faulty line extender before the tap.

If there does happen to be alot of noise on your wiring, your modem sucks at detecting it.

It could also be conductor suckout, but that is usually more detrimental to your upstream traffic.

In a nutshell. I think it originates on the carriers lines.

If not, I think you may have a bad cable, possibly a kink, or a bad fitting, possibly because of rot or suckout. See if you can get a tech to run a new line straight to the modem ( looks like it runs outside along the house )

Just make sure that tech gets up there and checks that TAP one way or another. It should be required by his superiors to certify your premise as well as their line equipment before he leaves. That is mandated by the FCC.

Hmm interesting. Will look into this. Thanks thumb.gif
