My Internet has been flaky since Comcast took over sometime in June/July :(.
Luke,
I suspect (though I can't confirm) that the total number of splits is the issue, not necessarily where they are. I think its like the REN (ringer equivalence number) on phones. If there are 5 splits on the line, each one gets 1/5th the signal strength. The total "bandwidth" coming into the house from your single connection is what gets split. So splitting into 2 lines, then splitting one of those into 4 is no different that just splitting the first line into 5. The overall signal is degraded with every split, regardless of the physical location of the splits.
Did any of that make sense?
Tell to run the trace, bet they have a line amplifier going bad.
I got a free month of internet and TV because the tech would not listen. Besure to get the who, what when and where down in writing. So you do not forget.
I have both cable tv and cable internet. There is a splitter under the house to send tv to each of the bedrooms and family room. One of those cables goes into the bedroom where the internet modem and router are located. Everything works fine.
The splitter has 1 in port and 4 out ports, no amps in the system. All 4 out ports are in use and have a tv on each one plus the modem and router in 1 room.
AT&T was better here on the peninsula, SF bay area, but comcast has only had 2 outages since it took over in this area.
Make sure the splitter you have has at least 2 out ports. The picture showed 2 inports and only 1 out port. Not knowing how they are wired inside, could be the problem.
gl mac :(
I think you could get a better splitter but I'd think it would work
you might want to think about the coaxial
also the coaxial that's running thru the walls was it installed with the internet ? or is it old coaxial cable meant for tv.
also check your coaxial connections
I got some shielded cable at radio shack that had really crappy connectors on it.
they just slipped over the coaxial and kinda twisted on
which could become loose real easily.
I really need to get those tools like the cable guy
radio shack - they push the gold colored crap
They said I wanted the gold colored splitter
and I show them the little numbers on the label
The gold contacts are better conductors. Also, coax wire comes in varying degree of quality. The twist on connectors are flaky with a capital 'F'. The left split usually is rated lower than the other splits (they may be marked), use the lower rating for the Cable modem (50 Ohm, the others may be 75 Ohm). Also, you can get a male to male extender just to test the line without the splitter to see if it is the length causing trouble. I have gone 100' through a splitter with no problems. If you go out that far and extend further, you may have trouble.
Try disconnecting the TV's cable on the splitter (but leave the splitter) and see if you get up then.
as far as my setup is concerned (adelphia cable - east coast)
YOU CANNOT USE A POWERED SPLIT INTO A CABLE MODEM
attached is a diagram of how my cable is split
ive got my line split 7 times but the kicker is its split initially where the signal enters my garage by a non-amplified splitter and then again by another non amplified splitter
the only times i amplify the signal is when the cable line goes into a tv or a capture card
ill take a picture of the splitter when i get home
A 'powered' splitter is a repeater (or amplifier, or signal booster). Are all of the splits in the Garage?
I spoke with a cable guy, and he suggested (which defies logic) that all the runs go back to a single split in the garage. Each physical split causes signal loss through the entire network. I found that I was able to remove ALL of the amplifiers and the signal was fine. Try this, unplug both amps and see where you are at. It is time to troubleshoot and see how far you can go. The filters are critical to isolate the cable modem.

gold contacts are better conductors
but do you really think those splitter are a plated with gold ?
not just the contact mind you but the whole thing
ATTBI aka Comcast here in Orygun installed a simple 3-way splitter when my cable was installed. I then bought an ATI all in wonder vid card and wanted to run TV straight to it. scrounged up a splitter from my hardware box. Installed it and ran cable to PC. No problem.Keep in mind,my internet cable was still on original connector. Then i wanted to connect VCR to PC and also have it receive signal for TV reception Besides the fact I wanted my other VCR to be connected to TV cable source. What i finally did was buy a powered splitter from Radio Shack(yeah,,i know,but it was the only place i could find one:rolleyes: ). It was specifically for cable TV 'and' internet connection. Which meant it was a 2-way throughput critter. It also has an adjuster for fine tuning the gain. Was not cheap, usd$50.00. I now run all units including cable modem off it with no problems. Played with the gain control a couple of times and actually improved internet scores. Took the original 3-way splitter from comcast and split the line at PC for VCR connection. Main thing is that splitter must have "two way" feed for internet use and the 'input' connector 'must' be used for input, 'not' output...
Each time you split the signal with a passive splitter it drops by 3db. A 3db drop is half power. Split it twice or use a 4 port splitter and you end up with 1/4 of the original signal at the output ports. Keep running through splitters and you end up with 1/8 then 1/16 etc. It starts to drop pretty fast. If you do use an amplifier you may want to check and see if it's bidirectional, amplifies both ways. A lot of the older cable TV (non digital) amplifiers only amplified the upstream signal. You want to amplify the signal both ways. Actually in reality you don't want any amplification, all you relly need is unity gain. :D
