    is it safe to leave my dsl interface, routers, wireless ap plugge din and on all the time, it's just that i am using VoIP and it requires that it connected to the net naturally enough for it to work so usually I would just have the stuff on for a couple of hours a day and even then they feel really hot, do they cool down? Also is it safe to have all the cables, rj45, rj11, power etc etc bunched together under the desk?

    someone left a towel on my wireless router earlier, and it just turned off. i took off the towel and unplugged it for an hour and it was grand. they are devices that are supposed to be plugged in all the time so i wouldn't worry about it, just make sure the vents are clear so they can cool down themselves. the cables would carry little if any current, wouldnt worry about it.

    No, they shouldn't overheat, they're designed to be left on. Best not put things on top of them tho.

    Well I have a Zyxel 623 and a 8port Switch setup to provide BB accesss to 3 computers.

    Havent unplugged the switch in months and appear to have solved the Zyxel locking up every week or so(I hope).

    There should be no problem leaving them plugged in as long as they dont feel very hot to the touch.
    I have mine screded onto a board about 30-50cms from the radiator and they never feel too hot when the radiator is on.

    The cables carry a low voltage that will shock your tongue if you like biteing down on such things...hahaha!!!!

    The operating envirnoment for my router(Zyxel 623) is from 0C to 40C.
    Outside those limits is is priobable more prone to locking up.

    Sourced from:
    ftp://ftp.zyxel.com/p623_series/document/p623_series_V.2_Datasheet.pdf

    Other routers must have similar temperature deviations.

    how much power do they use? like how much a month generally would it cost to leave a router on all the time?

    What is a unit(KW/hour) of electricity priced these days and add vat = X

    Find out how much they drain in an hour...then day...then 30days and you get your answer by multipying by X.

    A typical bulb is 100W....on for 4 hours a day would use a unit every 2.5 days.
    30/2.5 multiplied by cost of a unit equals the cost over a month.
    So if a unit is 10c then it costs €1.20 a month to power a bulb over a month.
    A router would use less power...but being on 24hours a day the cost could come to a couple of euro a month.
