Thanks Eric.
Also, on the back of this, Eric stated that in the early days of Broadband, most routers were USB powered and as such were switched off as soon as the PC/Laptop was switched off. Back then though, only fixed-rate Broadband was available and wasn't tied-in to the DLM management sytems we now have on rate-adaptive products.
So, my belief (and that of all SP's) is that by turning the router/Hubs off on a regular basis, ie- every evening, then one's speed will suffer enormously after a certain period of time. I'm not saying that turning it off every now and again will affect it, but at least once a day will !!
As per Eric's comments, it's in no way personal .............. I just know I'm right.
