It strictly depends on the model. Most routers have to be restarted in order to enable port forwarding.
You will need to connect your PS3 to a router, and the router into your broadband modem. You may need to configure port forwarding for your games to work. Go here: http://www.portforward.com/english/routers/port_forwarding/routerindex.htm for a list of routers and how to configure port forwarding.
No. Router are designed in the way they can work 24/7 for many years. Sometimes you need to restart it but it's not a big deal.
You need to disable SSID broadcasting and enable wireless security.
You need to have a router which would allow forwarding to your network from outside. It's better to set port forwarding as well. Also you will need to know full name of your computer including the domain. Also make sure that your ISP allows such connections.
You need to log in your router, and enable security for wireless networks.
you need to hold down ctrl and alt and delete not for to long though or u will restart your comp
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.
Well Port Forwarding is really only, opening ports and making them special to let a one connection on it. The main purpose for me is for gaming, you need to port forward for a game to run a dedicated server if the game allows, like Quake 3 arena, or GTA's, or Call of Duty's ect.
You would need a wireless router, which you install a password when you get the router and apply it on your iTouch to use Wi-Fi.
You plug your wireless into dsl router (you'll need to configure your router), and then configure your computer to the wirelessJust get a lan cable which is usually ships with wireless routers. Connect one end of the cable in wireless router port which is called wan or intertet. Another end of the cable connect to your modem. Then restart the modem and the router. Sometimes you might need to change settings for internet coneection and DHCP server. But usually it's not required.
You don't have wireless network cards you have to buy it or you have to get a lan cable(s). After that connect your router to the modem if you have it. And connect all your computers to the router. Usually default settings allow you to work with internet and inside network without any correction of default settings. After that restart your modem (if you have it) and restart your router. Then Start->Run->cmd, press enter. ping (one of your computer's Ips), for instance, ping 192.168.1.3 If it doesn't work out you have to configure DHCP server for your router, but it's already another question.
That depends on you modem/router, usually its auto, so if you dont need it it wont enable it
