What does 12.7w on 24/7 for a year add up to ?

A good rule of thumb is that 1w on 24x7 costs ~ Â£1 per year

Well my old VM modem used 2.7 watts so I am using an extra 10 watts per hour to do the same job,

I work it out in my case as an extra Â£1.05 per month

an extra 10 watts per hour = 100 hours to use a unit at 14.5p

720 hours in a 30 day month divided by 100 = 7.2 units x 14.5 = 104.4p

so an extra Â£12.53 per year,

Of course, you could switch it off when you're not using it. No, I don't either

But in these energy-conscious days, a 5-times (ish) increase in consumption to do the same job does seem a bit strange.

I know but would it start again? no way would I take that risk

Think those flashing lights are the culprit as far as the extra power consumption goes,

Still they will look nice come christmas time, wont need the tree lights on so that should save me a bit

You need to seriously consider swapping your electricity supplier.

it would be nice if some of us had a choice

I Know (don't want to stray off topic) BUT

Just done the deal fixed till July 2013, its supposed to be 8% on top of current tariffs, My hope is that I get it back during the 2 years

Just come off a another fixed deal so had a 20% increase just for that and another 8% on top

So my point regarding this, is that power consumption of the HUB is high as a modem replacement only

I had hopped I could reduce my power consumption by taking out my Time Capsule and old modem and just use the HUB instead

Maybe after the R28 firmware upgrade the next one could dim the HUBS lights, as this is were I believe the power go's

Don't get me going again on energy prices,

The lights are most likely plain led's which take a miniscule amount of power. The real drain will come from the router/main cpu chip and wireless radio. Even if there were seperate chips for the router and modem, the user interface would most likely be controlled from the main cpu so switching that off would not likely be an option.

I'm sure we'll find out soon enough once R28 is released.

I've not seen anybody post up the consumption in bridge mode but there is known to be a discrete WiFi board which could be powered down and although the main processor can't be turned off the switch circuitry presumably could be or at least run at reduced power (some switches have a "green" mode). I imagine the power required by the CPU should also drop with the reduced load.

I guess it all depends on how skilled the firmware coders are and how bothered they are about your leccy bill...

So - probably unchanged then

Compared to having to fork out for a router to do the job the supplied hub should be doing the extra power cost is pretty small beer.

I agree with you entirely, and had hopped I could just use the HUB and take out my own router

This would have reduced power consumption for me, (and helped the planet for everyone else)

But sadly it's not worked out like that

Come on VM, some of us are waiting. I want to upgrade to 30 meg because the current 10 meg is pathetic. The STM limits are so low I can't even watch a single 1 hour HD TV show at peek times without being clobbered. I just need the Superhub to support bridge mode so I can use my own router.

Either that for just give me a proper modem...
