Same outlet for Directv and TWC cable internet?

[SadieJack]

Is there a simple way I can connect my TWC modem (using a coax cable) to the outlet that I now have connected to Directv (also uses coax cable). I tried a splitter and it did not work.

Without actually eyeballing the exact cable setup, it is impossible to say.

Do you have service with both Dish and TWC?

No, there is not, as they use similar frequencies on the copper. They need to run on separate coax lines.

Now, back in the day, when the frequencies for cable internet (which used to be lower on the MHz spectrum) and satellite TV were very different, you could use coax diplexers, one at each end, set at the correct frequencies to carry both signals over the primary line and then separate it at the modem. Nowadays, the frequencies overlap.
