I've been happily using my ADSL wireless router for five years, only switching it on when I use it which is typically in the evenings and at weekends. Over the past fews weeks I had a dramatic drop in speed and logged a fault with my ISP.
They said that there was an (IP) profile mismatch on my account which they have rectified and early indications are that the performance has been returned to normal.
However, they have advised me that the router should be constantly plugged in to the telephone socket (it is) and left switched on. I'm not keen on leaving it on all of the time, mainly from an environmental point of view (every little helps, right?), but also to stop it getting too hot.
Can turning a router off when not in use degrade the performance of the broadband connection?
