I am new to the use of routers and have just changed from a usb modem (St330) to a netgear DG834G router,it is fully installed and working. My question is should it be always on? all 5 lights are lit all the time. regards
No I wouldn't leave it on, mainly for the reasons that it would be an extra fire hazard and it would be using electricity needlessly. I turn mine off if it's not going to be used for more than a couple of hours. There's no advantage to leaving it switched on if it's not going to be used.
