Pre-wired Cat 5e but wires not terminated, hanging loose in basement

[srikanthr05]

Just moved into a new home and find the wall outlets for Ethernet not working as I (duh) expected them to. I had the builder run Cat 5e cables behind the walls and have 3 wall connection points in different rooms. But when the Comcast technician arrived, all he did was run a Coax cable from his box outside into the basement where the builder has left a bunch of coax and Cat5e cables tied together (not terminated) - and connected it to one of the coax cables in the bunch. Then connected the modem/router to the wall outlet in the living room via a splitter to run both cable and internet. That's when I realized the wall points for Cat5e aren't enabled! I tried the following but it did not work - connected the 3 different Cat5e cables in the basement by twisting the respective color pairs together - so 3 pairs of blue/striped blue etc. - idea being router is plugged into wall point in living room and this would make it one long Cat5e cable throughout the house and so activate the other wall points. Or so I thought.

Need help!! Appreciate it.
