New This isn't a case of Windows mentality
The issue with many cable modems is that there is no way built into the modem to cause it to do basic reinitializations (like "figure out what name the hardware that is attached to me expects to hear itself addressed by") is to start from scratch. So if you switch what you have plugged into the modem, then you need to power-cycle or they will forever talk past each other.

Once it is up, then barring a hardware change you can leave it that way for months.

Cheers,
Ben

New Not only that...
... but my cable modem doesn't even have a power switch.

So if something changes to the point where it needs reinitialization (like when Comcast changed to their own network from @home), I have to unplug it, then plug it back in. :-)

New Also, a power glitch can put the cable modem into limbo.
Had that happen once. A short power disruption left the Motorola cable modem in a weird state that made it look like there was no cable signal. The Road Runner tech support guy suggested power off/power on before sending out a repair guy. Good thing!

Duke Energy (the local power company) is notorious for power blips so my cable modem is now on a small UPS.

New Happens to hubs too.
I've had to power cycle 10BaseT and 10/100 hubs that jammed because of a power fluctuation. Everything looks fine, but some (or all) of the ports don't work.
