If you lose channels for the next 2 weeks at around 10-11 am for a few minutes then this is normal for this time of year.
Basically the sun is right behind the satellites, and the energy from the sun will swamp out the weaker satellite signals.
There is nothing you can do about it, as it can even affect “big dishes” also.
Rebooting the box will not help – apart from killing time until the signal returns again
It does not happen on ALL channels, as some are stronger than others.
This loss of signal happens twice a year in March and October – around the time of the equinoxes.
