One of the projects to tackle before the new roof installation is the running of data/coax/phone to all of the rooms.
Friday before last, Abril roofing came by to clear the roof of gravel in prep for the new foam room. After it was cleared, the wiring was next.
It was a bit weird drilling 5/8in holes into my ceiling (and 2in holes for the main runs), but it all went well and now we have each room wired for CAT5e, phone (CAT3) and coax (cable). The wireless network (AirPort) is also contained in the box.
The parts came from Parts Express (Wired Home brand) and the cable itself came from -- of all places -- Home Depot, who had the best price. We also ran one run of in-wall speaker wire for rear speakers in the main TV room (adjacent to the kitchen).
Update: Since the initial install, we've moved the Airport router out of the cabinet and positioned it high on the wall above with a wall mount. The signal is indeed much better.
Thanks to Joel and Brad for the help (and Chris for the network advice).
