We had a very loud lightning strike last Friday night. Woke up to discover a couple of cable boxes not working, our TV had one HDMI connection fried, the modem was out of order, and a DVD player was also toast. All the toasted items were connected to surge protectors.
Right next to the modem sits a UPS to which my desktop and router were plugged in. As near as I can tell, they are both fine.
Thank goodness for the UPS. Should I plug the modem into it as well, even though it has a backup battery inside? I've read where that is a bad idea.
