      yes but before i do that:

      how much power do these routers draw anyway?

      and

      when leaving the router on, the web is accessible even before
      my software firewall has loaded when i switch on the comp, is that safe?

      also what are the disadvantages of turning the router off when not required?

      I did measure it once and it was about 6 watts. With my electricity supplier, that works out to be about 75p a year.

      As for your software firewall, I really wouldn't worry about it. The router effectively acts as a firewall, and the only reason I have the Windows firewall switched on is to stop Windows moaning about it. Some people would say that a software firewall potentially blocks viruses etc that may be on your PC from attempting to make outbound network connections. But provided you use a properly updated virus checker, that shouldn't happen. In my experience, a software firewall is more a hindrance than a help.

      As for the disadvantages of switching it off, one of the biggest killers of "solid state" electronics is thermal stress. When you switch the router on, it heats up and that in turn makes things expand very slightly. When you switch the router off, it cools down and the components and the circuit board shrink very slightly. This repeated pattern of expanding and contracting can shorten the life expectancy of the router.

      EDIT: Sorry, one point I should have made is that if you've put your PC into the DMZ, then you absolutely must have a software firewall on the PC. But in the very short period of time that your software firewall takes to start up, there's very little chance of anyone managing to do any harm to your PC. There's millions of IP address and the chance that someone might be scanning your IP address at exactly the right moment is very, very small indeed.

      With wireless on, mine consumes 7W with wireless off 3.5W.

      agree with all of what you have advised, i also do the same for my pc to be honest, its using a very new high efficient power supply, and i prefer it to be on all the time than be constantly rebooted, as it would be with the amount of hammer it gets.
      With regards windows moaning, i presume you are aware that you can tell windows that you will monitor the firewall yourself i belive then you dont get the constant moaning.
      I dont have software firewall at all, and am totally confident in the routers firewall capabilities.

      Ah, well you see I didn't actually know that. But the list of exceptions in the Windows firewall has now got to the point where I never have let anything through. But I'll bear that in mind the next time I set up a Windows machine - it'll save me the annoyance of having Windows constantly pestering me the first time that I ssh into my server, the first time that I use ftp, etc., etc., etc.

      Re: Router Left On Or Switched Off?

      no they are made to be left switched on, just like network switches, which the router is anyway, as it has one built in, ive had a netgear switch that has now been constantly powered on for over 6 years... as brian said above they only use 3.5W without using wi-fi and 7W when wi-fi in use or swithced on.
      It doesnt do the router anygood at all being switche don and off, which could possibly be a daily occurence i presume?
      hope it helps
