Re: [connectivity] What steps to take with intermittent disconne o Make sure that all your POTS telephones are filtered from the DSL frequencies. This can be done by individual filters (usually suppled by the phone company) or by a single unit that separates POTS from DSL.
o Make sure that all your premises wiring from the external interface block to the the modem is in good condition with no corrosion or seriously oxidized copper. Clean the insect litter out of the external interface assembly.
o Put an oscilloscope on the phone line and observe how much noise there is relative to the DSL frequencies on good days and bad days. (I never had to do this, so I can't relate values to look for.) The modem may be able to report signal-to-noise ratio.
o If all else fails, switch to GWI if they have a presence in your town. Then if there are problems they can demand Fairpoint check the lines out. I assume that the rules requiring colocation still are active.
Now dual WAN on Fairpoint FAST (ex Verizon FiOS)
Formerly dual WAN on Verizon and GWI DSL
