Whenever there is significant rain or wet snow before the ground has
frozen, the dial tone is accompanied by an annoying hum. Calls can go
out and be received, but it is extremely difficult for parties at
either end to hear. Also, when this occurs, I cannot connect to the
Internet. 10-12 hours later when conditions are dry, the phone works
OK. Diagnosis? Treatment? Thanks

You've got water getting into line somewhere creating a partial

insulation....
