Modem Towers

Do modems towers go bad? Everything was working fine when I left home yesterday but when I returned no internet. I have followed all the instructions(many times) to reestablish connectivity, to no avail. There are no lights coming when tower is plugged in. The electrical outlet is functional with all other devices. Its really an inconvenience to have to wait until next Thursday before tech support can come to my house. This isn’t timely customer service in today’s work/home environment.,
