Re: [TWC] Upstream Power is +56.5 dBmV, please help.
Thanks for the reply, I read the post but now I feel a bit lost...
So you're recommending I add more splitters? I thought my weak signals was the reason they removed the one splitter from the room. If you don't mind telling me a bit more, I'd like to hear it. |

MUST BE a bidirectional amplifier (active return). They come in 2-4-8 ports too eliminating the need for splitters.
There are other brands but beware the stuff you buy at radioshack is junk so make sure you buy professional grade bidirectional amplifiers.
Please note that the following link is for a passive return (no upstream amplification)

I've seen new PCT 4 ports active return amplifiers at ebay listed for around $50.
My home in McAllen has the 8 port version with each output going to a different room. I have no splitters here. |

Are today's readings, when both technicians were out here this week I inquired about splitters (which they recommended we remove) filters (some had never heard of), and amplifiers. Which I got mixed responses. I was told the amplifiers would only affect my channel signals and NOT my internet. I really wish these technicians would have their infomation together. So overall with the information I've provided I need an amplifier? Will this replace that 3-way splitter in my garage? |

| In general, consumer-grade amplifiers are not a good idea for bi-directional (internet and digital set-top boxes) cable services. Worst-case, they can amplify noise on your line and send it out to your neighbors, thus ruining service for many people. If an amplifier is truly needed, it should be a professional-grade one that is supplied, installed and adjusted by your ISP.
Also, in many instances, bi-directional cable amplifiers will only amplify the downstream signal, and will thus not do anything to reduce the upstream power.
I know it has been frustrating for you, but, other than the suggestions about checking your cables and trying a replacement modem, the solution is going to have to come from a TW tech. Only they have the measuring equipment (which costs way too much for you to even think about buying for yourself) to see what is going on plus the experience needed to take the proper action once they make the measurements. |
