splitter issues?
Hi All,
I most recently moved a tv I used in my bedroom into another bedroom where our family computer is plugged in. I have a splitter connecting the netgear router/modem from cox and the tv straight from the wall. The router/modem seems to be working just fine as I am writing you using the computer the internet is hooked into, but the tv has a very snowy connection and does not seem to be working. I have been going through the channels auto preset but each time it comes back, its a snow screen on most of the channels, and a few I can see a sort of a picture but snow sound and some audio. I had the same issue in the other bedroom until I had a cox cable guy come out to fix it and he was able to get the channels in my bedroom. Now that I moved the tv , it seems to be having the same problem.... I have used other tv's in this other room before but the computer was not connected and I wasn't using a splitter. Any suggestions? This is an older LCD tv from 2007, still in good condition. I bought a new tv in my master, so I just moved my old tv to a guest room/office.

Copy and Paste your Modem Signal Levels: http://192.168.100.1/
Post a picture of the splitter, is it just a 2-way (-3.5dB) Commscope or Antronix splitter?

My guess is the TV isn't set to Cable or CATV mode. Instead its set to ANT or AIR, which is keeping you from seeing your cable channels. Should be under Menu>Setup, but I would need to know exact model of TV to give specifics. Probably reset when you moved it into the new room, since it was unplugged.

You may be using an analog splitter. A splitter rated under 1 GHz (1000 MHz) will have problems passing digital signals.
Look for a bi-directional splitter with a frequency range of at least 1 GHz. Don't go too high with the frequency range because 2-3 GHz is for satellite signals.

Horse pucky! There is no difference in splitters as far as passing analog or digital signals is concerned. Many digital channels are sent at frequencies below 200 MHz. A 1 GHz splitter will pass those signals that Cox put on carriers greater than 750 MHz much better than will a 750 MHz splitter, that's all. Last time I made a count, Cox had about 50 HD signals above 750 MHz. Plenty of SD and HD digital channels below 750MHz.

It's not just the frequencies...but the innards of digital splitters. Analog splitters contain a thin wire and ferrite cores, which were great for early CATV and MATV systems.
Digital splitters contain printed circuit boards with the electronics to keep good impedance-matching across the band. They also have capacitor coupling (low intermod), higher return loss (a good thing), and higher port-to-port isolation, especially in the return path.
I don't suggest spending $30 for a hyped-up splitter, such as from Monster. A $5 digital splitter from Best Buy would be fine. If they're still in existence, stay away from Radio Shack.
