Rap, having to set up or restore the home system is the price we pay for not letting the IP company send a tech out who fiddles with stuff and leaves you with whatever their default setting is, and not giving you much information. I've helped several friends with the systems the cable or phone company left behind, usually with setting up a booster or extra ports for the router.

If I ever get the house leveled (right now it is at its most level time of the year, the soil is moist and the cracks have almost disappeared in the walls and at the ceiling edge) I'll put in a sprinkler system. That I will diagram and supervise because too often those sprinkler guys just wing it. (Neighbors up the street paid for a high dollar system only to find later that they put in a cheap set of buried hoses and such, workmen long gone along with their cash).

MOM should have Gluon train to help with this stuff, I bet a duckdog would be great at digging and working out the water end of things.
