Cable Splitter: TV/Internet

Can I split the incoming coax line into a feed for TV and a feed for the internet to a cable modem? If so, what kind of a splitter should I get (and suggested sources if available)?  The physical distance from a proposed split location to each device is about 10 feet.

 

Thank you!

Sure, provided that the signal stats / connection quality will allow for the added attenuation that a splitter will introduce. Comcast uses this brand (among others);

If you want to get a general idea about the signal stats please post them here. Try getting them from the modem here at this link; http://192.168.100.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Yep. You've got enough wiggle room for it.

Re: Cable Splitter: TV/Internet

Hi,

 

this the info of my modem.

 

Downstream power level: 2 dBmV  

 

Upstream power level: 44 dBmV

 

 

Is it able to connect the cable and internet through a splitter?

 

Thank you

Re: Cable Splitter: TV/Internet

Hi there, I'd like to use a cable splitter and I have the following values from my modem, connected directly to the wall (with the internet working):

 

Frequency 693000000 Hz  Signal to Noise Ratio 37 dB  QAM QAM256 Network Access Control Object ON Power Level -5 dBmV   The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading
Upstream ValueChannel ID 1 Frequency 36400000 Hz Ranging Service ID 102 Symbol Rate 5.120 Msym/s Power Level 54 dBmV

 

After splitting, I cannot receive any information from my modem, and the modem is hung up with a constant flashing SEND light. It's a motorola SURFboard SB5120, and the splitter I am trying to use is an EXTREME Broadband Engineering BDS102H that says, -3.5dB on each OUT port, as well as 5-1000MHz / EMI - 130dB. I'm not sure what those numbers mean, but I'd like to know what kind of splitter I need to use so that I can watch TV and use the internet. My current setup was fine (for a couple years) until this morning. Any help you could provide would be great!

 

Thanks!

The signals are already too weak to allow for an additional splitter. There are likely already too many in the line. Have you looked to see if any excess / unneeded ones can be eliminated / re-configured ? They may be hidden in the walls somewhere or in a box on the side of the house or the signals may just be already too weak from the street / pole drop with which you would need a tech visit to investigate and correct.

Re: Cable Splitter: TV/Internet

No to possibly at that outlet / line. The upstream power is borderline. You can always try and see what happens.
