We have noticed that since we got a land line and broadband our power bills went up by ~£35. http://www.ukpower.co.uk/tools/running_costs_electricity/
Using this calculator I worked out that it costs us £19 a month to power our wireless router costs.
It reads 230V ~50Hz 0.5A, works 720hours a month (always on), the electricity costs us 23p pkw ( ~6p at nights but I dont include that in this calculations)
Same with phone wichs runs at 0.45A :(
Both plugged in all the time would work about £30 a mot (thats including lower night rate)
Are my calculations right?
Do you experince the same 'problem' ?
