How can I connect an iPad, iPhone, or iPod Touch to my wireless home network?

Before you begin: You’ll need your network's SSID, encryption type (WPA2, WPA or WEP), and encryption key. You can find this information in one of three ways:
Review the sticker on the back of your router or gateway. The sticker displays the SSID and encryption key information. By default, some routers and gateways are configured as WPA. You may have to choose WEP if the device you wish to connect is not accepting WPA mode.
Use In-Home Agent to view your settings: You can access In-Home Agent on a computer that is already connected to Verizon Online. Within In-Home Agent, go to the Networking tab and select Retrieve SSID and WEP/WPA key.
Log in to your router or gateway from a computer already connected to your wireless network. The instructions you follow depend on the type of router or gateway you use to connect to Verizon High Speed Internet.

“ Special Note A” The encryption key “ IS “ sometimes referred to as “the Network Key ” both these terms “ mean “ the same thing. The “ SSID Key” and the “ Encryption Key “ ARE “ network specific to your “ ISP “! ( internet service provider) !! This means that they should ABSOLUTELY / POSITIVELY “Never ever “ be CHANGED by the “end” user!!! AKA “ YOU “!!


To connect an iPad, iPhone, or iPod Touch to*your wireless home network:
1. Tap the Settings icon.
2. Tap Wi-Fi.
3. Confirm that Wi-Fi is set to On.
4. Choose your network from the list provided.
5. Enter your network's encryption key if you're prompted and tap Join.
6. Tap On to automatically join networks your iPhone, iPad,*or iPod Touch has joined previously. If it detects a network it doesn't recognize, it will ask you before it automatically joins the network.
7. Tap the Home button to return to your iPhone, iPad,*or iPod Touch home page.
