Check the SSID of the wireless LAN router or access point using Canon MF/LBP Wireless Setup Assistant, and repeat the setup again.
|
Check network connection.
If the access point cannot be determined even after checking the network connection, check the security settings of the wireless LAN router or access point, and repeat the setup again.
|
Check the DHCP function of the wireless LAN router or access point network key.
At factory shipment, the machine's default settings have <DHCP> and <Auto IP> enabled so it obtains an IP address automatically. Enable the DHCP function on the wireless LAN router or access point and repeat the setup again.
|
Check whether the IP address of the machine matches the sub-network address of the computer's IP address.
If the sub-network addresses do not match, change each of the machine's IP address so they match. To view the IP address of the machine, follow the steps below.
General Network Address Determination Method:When the subnet mask is set as "255.255.255.0", it is the same value as the IP address with the part that is furthest to the right replaced by a "0".
Ex.:
IP Address: 192.168.127.123
Subnet Mask: 255.255.255.0
Subnetwork address of the above example: 192.168.127.0

Check whether you have selected the wrong SSID.
Check the SSID of the wireless LAN router or access point using Canon MF/LBP Wireless Setup Assistant, and repeat the setup again. |
Check the wireless LAN router or access point network key (WEP key.)
Enter the correct network key (WEP key) and repeat the setup again.
|
Make sure that <IPv4 Address Range Settings> or <IPv6 Address Range Settings> is not specified for the machine.
If it is specified, change the setting so that IP address and MAC address of your computer can be permitted.
|
Check to see if <SNMPv1 Settings> is set to <Off> for the machine.
You may not be able to specify and browse each item of the machine from utility software that uses the SNMP protocol to obtain the information.
Change <SNMPv1 Settings> to <On> when it is set to <Off>.
|
Make sure that <Dedicated Port Settings> is <On>.
|
Check the SSID of the wireless LAN router or access point using the Canon MF/LBP Wireless Setup Assistant.
|
Check network connection. See the Starter Guide.
|
When multiple networks are used:Check whether each communication channel of the wireless LAN router or access point is spaced five or more channels apart.
Not setting the channels far enough away from one another may lead to interference between channels. Set the channel as far apart from other network channels as possible such as Ch.1, Ch.6, and Ch.11.
|
If the machine's power is turned OFF and ON it is because a new IP address has been assigned.
When using DHCP, consult your network administrator and perform one of the following: Setting the DNS Dynamic Update function
Setting the machine so that it uses the same IP address every time it starts up
|
Make sure that the correct printer driver is installed to your computer.
When switched to wireless LAN connection from the other method (USB connection or wired LAN connection), uninstall the MF driver.
Once uninstallation is complete, reinstall the MF driver. See the Starter Guide. |
Check the printer folder to make sure that the printing destination of the computer is set to the machine.
|
If the broadcast does not need to traverse the dial-up router, configure the dial-up router so that the broadcast does not traverse it. If the broadcast needs to traverse the dial-up router, run a check the dial-up router settings.
|
When a DNS server exists in the external network, specify the destination IP address instead of the host name. This also applies when the device to which you want to connect the machine and the machine exist on the same network.
|
When a DNS server and the machine exist on the same network and the device registered on the DNS server exists in the external network, run a check the settings.
|
Certain settings on the wireless LAN router or access point will not allow connection/communication with the machine.
Connection/communication with the machine is not possible under the following settings.
The machine is not able to find the wireless LAN router/access point for the following:Stealth function: Enabled
Deny ANY: Enabled
Channels: Ch.1 through Ch.11 (US)
The machine cannot connect with the wireless LAN router/access point:MAC address filtering: The MAC addresses of the machine or certain computers are denied access.
The Remote UI is not displayed because the machine cannot communicate with the wireless LAN router/access point:WEP key number that you are using: Set from 2 to 4
Automatically generated WEP key on wireless LAN router or access point (Hexadecimal)
An encryption method used when only IEEE802.11n communication is used: WEP or TKIP
