If the computer doesn't already have one:
1. for a desktop, get a PCI plug-in card (you'll need to open the case), or use a USB plug-in device,
2. for a laptop, use a PC Card (older technology), or use a USB plug-in.
You'll also need an access point (hot spot, wireless router) connected to the internet.
You'll need to use the correct software (drivers) with whatever device you use, you'll need to be near an access point (hot spot), and you may want to activate wireless security so no-one else can piggy-back into your network and steal bandwidth, or (worse), screw up your system.
It is different for every router and computer. It should be in the router software that you set up the router with. JUST JOKING!
either ethernet router or wifi router
You don't "make" your router have wifi. It either has it or it doesn't. Wifi is available from a wireless router, so check to see if yours is wireless. A wireless router will usually, but not always, have antennae sticking out of it.
Typically, one of three ways: An ethernet cable, which is the most common. Merely connect an ethernet cable to your computer and the router. A USB cable, less common. Same connection. A Wireless system (WiFi), becoming widespread. Requires WiFi antennas on both the router and the computer.
either via wifi or hardwired..
You will have to have a router to make a wifi network if you only have a wired modem.
Wifi enabled tablets connect security by the security that's setup in the wifi router. If you can connect to the wifi without needing to input a password then your internet is likely not secured. at&t has setup wifi service what do you do next?
no they do not only the ability to make a WiFi or ethernet connection. You must purchase a router or modem.
You can make WiFi with your own ball baton ads12 router modem by bridging the modem/router to work as a modem only. You then configure the D-Link's WAN for your connection.
you need a router for ur computer u can find it at best buy
Well, if you purchase a router, any computer in the same household would be able to connect to the internet connection wireless. There might have be an installation CD that comes with the purchase of the router to set up wifi on the computers.
There is no router on a PS3. There should be a router connected to your computer to give you wifi. The IS a network adapter built inside the PS3 that will connect to your router. For connecting: http://www.youtube.com/watch?v=NC7aPylbI3M
