(google: ethernet cable oscillator continuity)

I know i've seen similar gadgets, but I'm not sure how/where you would 
find a continuity break in an in-wall cable.

Usually, the parts subject to mechanical/physical wear and tear are the
first to go, I'd take a close look at the jacks and where the wires punch
down or are crimped/connect.

It's also handy to have a cable stub or two that you can use for loopbacks
and continuity tests, I think for ethernet you want to connect pins 1 to 3
and 2 to 6 (with that little tang thing facing down)
