Solution
To connect the machine to the computer via wireless LAN, select wireless LAN using the operation panel. For how to connect to and specify settings for a wireless LAN/wired LAN, see "Getting Started". Note that if you change the setting from <Wired LAN> to <Wireless LAN> or vice versa, you will need to uninstall MF Drivers installed on your computer and then reinstall them. For details, see the "MF Driver Installation Guide" from the Canon website (canon.com/oip-manual).
1. Tap <Menu> in the <Home> Screen.
2. Tap <Network Settings>.
- If a screen for entering a PIN is displayed, enter the PIN with the numeric keys and tap <Apply>. For details, see the "User's Guide" from the Canon website (canon.com/oip-manual).
3. Tap <Select Wired/Wireless LAN>.
4. Tap <Wireless LAN>.
You can search the wireless routers (or access points) available for connection and select one from the display of the machine. For the network key, enter a WEP key or TKIP. Before selecting a wireless router, check and write down the required setup information, including the SSID and network key, see [ Checking the Access Point Name or Network Key (MF249dw / MF237w) ].
NOTE
Security settings
- If the wireless connection is set up by selecting a wireless router, the WEP authentication method is set to <Open System> or the WPA/WPA2 encryption method is set to <Auto> (AES-CCMP or TKIP). If you want to select <Shared Key> for WEP authentication or <AES-CCMP> for WPA/WPA2 encryption, you need to set up the connection using the manual entry method. For details, see the "User's Guide" from the Canon website (canon.com/oip-manual).

- Wait approximately 2 minutes until the IP address settings of the machine are completed.
Signal strength
- When more than one wireless router is available for connection, the machine connects to the device with the strongest signal. Signal strength is measured using RSSI (Received Signal Strength Indication).
NOTE
Reducing power consumption
- You can set the machine to enter <Power Save Mode> based on signals emitted from the wireless router. For details, see the "User's Guide" from the Canon website (canon.com/oip-manual).
