iMac wireless connection - is this true?

If you have a Wi-Fi router then you're set. You're worrying about absolutely nothing!

Have you turned on Wifi on the iMac: System Preferences>Network?

If there is no WifI entry you can create one by clicking on the '+' sign bottom left and it should become clear.

If your router has WiFi capability and is not just an Ethernet router, you should be able to connect you iMac using the iMac's built-in Airport/WiFi receiver. If you need to set passwords and encryption for the router, you need to install the router software either on the PC or if there is a Mac version of the software, install this software of your iMac.

The should be an Airport WiFi symbol at the top right of the main Apple menu, you need to click on this and turn Airport reception on. Your router should show up in a list, you click your router and enter any password you setup to activate the WiFi reception.

If your router is just an Ethernet style router, YOU will need to go out and either purchase an Apple Airport Baae Station router, Apple Airport Express WiFi transmitter or purchase a third party WiFi capable router.

Iin order to have WiFi, you need a router that transmits WiFi signals out from the router. Without this capability, you can not make use of any WiFi capable technology in your home.

In the upper right of your screen you should see an icon that looks triangular, if it has lines through it then wi-fi is already on and you are connected. If no lines are present then click it, choose turn on wi-fi, select your network and input the security coded (if any) and you're done. If there is no Wi-Fi symbol in the upper right of the screen open http://support.apple.com/kb/PH10672 for instructions.

If your router is already a WiFi type router ( I.e. Wireless N router), you and your iMac are set to work wirelessly.

Do a search for properly setting up just the iMac to receive Wifi reception.

The password the WiFi network requires should either be on the paperwork that came from your ISP or likely is on the bottom of the router - it'll say something like WEP Key or WPA/WPA2 password.

Whoever setup your network must have put a password in, this is a very good thing. However if you don't know the password you will need to probably reset your router. You will need to locate it and then contact the manufacturer via their web site and look for instructions on resetting the router and setting up a new WPA password. Keep that password in a safe secure location because you may need it down the road.

If you know the person who setup your router, you need to get the WEP password from this person.

Also, the software for accessing the router is probably on the PC. If maybe good to have this person show you where on the PC the software resides and how to use it for future use.

In additon, you might be able to go to the router manufacturers website and see if they have a Mac version of their router software and perhaps download and install the software onto your iMac, also.

Wifi routers come setup with an initial WEP password. This password is located on the bottom of the router and you should have a duplicate with the router's paperwork. If this is the correct password, I would right it down, again, and put it somewhere safe, but where you can remember where you put it for future use, if it's needed, again.

Good Luck!
