Installing the printer on a wireless network

Wireless network compatibility

Your printer may contain an IEEE 802.11b, IEEE 802.11g, or IEEE 802.11n wireless print server. Your printer is compatible with IEEE 802.11 b/g/n routers that are Wi-Fi certified.

Note: If your printer has an IEEE 802.11g wireless print server and you are having issues with an n router, then verify with your router manufacturer that the current mode setting is compatible with g devices, as this setting varies depending on the router brand or model.

Supported network security options

The printer supports three wireless security options: WPA2/WPA, WEP, and no security.

WPA2/WPA

WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access 2) offer stronger wireless network security than WEP. WPA2 and WPA are similar types of security. WPA2 uses a more complex encryption method and is more secure than WPA. Both WPA2 and WPA use a series of characters, called the WPA pre‑shared key or passphrase, to protect wireless networks from unauthorized access.

WPA2/WPA passphrases must be:

•Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9. or

•From 8 to 63 ASCII characters. ASCII characters are letters, numbers, punctuation, and symbols found on a keyboard. ASCII characters in a WPA passphrase are case-sensitive.

Every device on the wireless network must use the same WPA passphrase. WPA security is an option only on infrastructure networks with access points (wireless routers) and network cards that support WPA. Most newer wireless network equipment also offer WPA2 security as an option.

Note: If your network uses WPA2 or WPA security, then select WPA Personal when you are prompted to select the type of security your network uses.

WEP

WEP (Wired Equivalent Privacy) is the most basic and the weakest type of wireless security. WEP security relies on a series of characters called the WEP key.

Every device on the wireless network must use the same WEP key. WEP security can be used on both ad hoc and infrastructure networks.
