Switching off electricity supply

[#1]

Hi,
I have been informed that my electricity meter is due for an upgrade in about a month. During this time all electricity will obviously be off. What is the correct process to powering off a netgear wnr1000 and what happens when the bt modem goes off on fibre. Will my speeds be affected for a few days while it re synchs?
Many thanks

Turn it off once and unplug router from the wall socket and leave it until the engineer is finished, then once you have stable power again turn the router back on.  As long as its only powered down once in a short period of time, then its no problem as far as DLM is concerned.
