My friend's internet service was out all week. She has the same ISP as me - a local satellite company. They came out and found that it wasn't their equipment. We had a bad storm one day last week with BAD lightening. Apparently, lightening had blown out her internal ethernet port. She's not using a mac -- she has a PC. She also has an external ethernet port so she is using that now and everything is fine. My question is... would an APS battery backup have saved that from happening??
