No, you do not have to.
Pull the plug.
to turn off the wireless signal, you only need to unplug the router. if that is no good for your purposes, go to www.whatismyip.com and type the IP it gives you into your address bar. this redirects you to the router setup, where you may be able to turn the wireless signal off
According the manual you cannot do that.
turn off her internet then u can do your work
Turn off for five minutes and then turn it back on
yup perfectly safe!
Your router goes on then off, as many times as you turn it, on then off.
Well, I would recommend turning off your wireless router for a moment if the wireless adapter tends to overheat often. It would be recommended to restart the router after turning it off to ensure it won't overheat as easily.
Turning off the router will not mess up the settings on the router. When you configure the router, it sames the information in memory. Some routers you must reset manually. Your configuration can be modified, but what ever settings you make are stored. Turn it off as much as you like. Sometimes if things get slow, turning the router off and restarting it will clean up some problems because it clears the cashe.
because the wireless is broadcasting it's signal, you can turn it off to the outside world in Windows 7, not sure of XP anymore LOL
Yes. In fact, this is the standard, intended way for a wireless router to work. ISP/Internet service DSL/Cable-----> Modem---->Router )))))) PC ---> Cable ))))) Wireless
Routers are designed to work 24/7. No, as the exchange might think your router is unstable and thereby reduce the speed of your broadband connection.
