Which Cable outlet for connecting Cable modem?

Hi,

When I called cable company to install cable modem in my house, the guy came and checked for all cable outlets and the cable splitters in the attic. Then he said that cable outlets are not conditioned properly to receive Cable modem signal. He then changed cable splitter in the attic and checked some signal and then said now they are ok.

When he said that cable outlets were not conditioned properly, I was receiving cable reception properly without any problem. My question is - what was he checking? What does it mean when he said that cable outlets were not conditioned properly?

Just curious.

 

prior to the advent of cable modems, digital TV, satellite TV and other such stuff, splitters only had to deal with signals in a cerrtain range. When all of these other things were added to the cable signal it became necessary to expand the signal range, and also to make the splitters bi-directional.

You must have these newer splitters, at least to your cable modem, or it won't work. Regular cable TV could care less.
