I don't. It looks like a lit Christmas tree. Twinkling with all of it's bright lights. I've also heard that if they stay on they are always running, creating high electric bills.

If your computer is directly connected to a modem then you may want to turn it off when it's not in use.
If the modem is directly connected to a firewall or router then there really isn't much benefit to turning it off when not in use.
Some providers do place a cap on total bandwidth usage and turning off the modem is a sure way to guarantee that no traffic is passing through the device.
I don't have a bandwidth limit. The modem is secured enough with passkey and the computers themselves have firewalls. I have laptops and computers throughout the house and the modem is in the 2nd floor. It would be a pain to to shutting down the modem and turning it back on repeatedly. There is no benefit. The device itself hardly consumes power.
