every snow storm or rain storm, satellite goes out for a time....I was told by my Direct TV to go outside and wipe off the snow and ice from the satellite with a soft towel to get my signal back on and it works.
finally had a service guy tell me to spray my dish with Pam. It keeps the snow and ice from sticking and last year only had to go out once to wipe it off...bad ice storm that time....the internet service is slow with land lines but reliable...unless some one hits a pole with their car. then the phone service is down and so is the computer... I have had phone calls that when I hang up, they call right back....fixed that one by throwing the phone on the bed and going to the kitchen for a cup of coffee...they quite calling back...
WD 40 works too.
