Until two years ago my brother in law's system (running
Redmond 'doze XP) was making its broadband connection via a USB port to the ISP supplied "horseshoe crab" (as I called it). When the system was powered off the USB modem was, therefore, powered down. There was never any problem with his throughput speed. Eventually, as he wanted to have wireless capabilities, he contacted his ISP who then provided him with a more up-to-date modem/router/WAP connecting via the system's Ethernet port.
My copper pair is completely unbundled -- I am LLU, with
TalkTalk as my ISP. I mention my ISP as it may have some relevance due to being different equipment from that of
BT. From day one, I have always powered off my modem/router at the end of the day and switched it back on the next morning. At present, I am not using my
2Wire 2700HGV but my
Netgear DG834Gv5. Here are the current statistics --

Note that although I am connected to 21CN equipment that is ADSL2+ capable, my service is "Up to 8 Mbps" i.e. is capped at 8 Mbps. As a result of that cap and due to the fact that I still have not rationalised my internal wiring
I have set the
DG834G to use
G.Dmt.
I would appreciate an analysis of the statistics by one of the appropriate experts (you know who you are
) . . . please pretend that I am a novice and know nothing.
Perhaps, once I
have rationalised my internal wiring, I should do the required experiment -- contact my ISP and request that my download SNRM be set to 6 dB and then leave my modem/router constantly powered up?
