Canon PIXMA MP620B Network Setup Troubleshooting - Page 3

Troubles in Setup/Connections 1 Connection checklist Before you proceed to Troubleshooting, confirm the following: □ The USB cable is securely connected to the correct port. □ The machine is turned on and the network device is on. If it is, turn it off and then turn it on again. □ If the firewall function of your security software is turned on, a message may appear warning that Canon software is attempting to access the network. If the warning message appears, set the security software to always allow access. □ When using a router, connect the machine and computer to the LAN side (same network segment). □ The machine's LAN setting is configured according to your connection method. To connect over wireless LAN, set Change wireless/wired to Wireless LAN active. To connect over wired LAN, set it to Wired LAN active. For the procedure, refer to "Machine's LAN Setting" in the printed manual: Getting Started. If you have changed the machine's LAN setting, set up the machine again following the procedures in "Install the Software" and onward in the printed manual: Getting Started. Confirm the following before setting up on a wireless LAN: □ There is no barrier or obstacle between the access point and the machine. □ The access point is operating in IEEE802.11b or IEEE802.11g (2.4 GHz). 2 Cannot connect to the access point (the access point is not detected) 2.1 The target access point is not detected • Refer to "1 Connection checklist" on page 1 and make sure there is no problem. • If the machine or your computer cannot communicate with the target access point, follow the procedure below. a Ensure that the access point is on and then click Update in the Access Points dialog box. b If the access point is still not detected, move your machine closer to the access point and remove possible obstructions, then click Update. c Ensure that your computer can communicate with the access point. d Unplug the access point from the power outlet and plug it in, then click Update. • Using your access point's utility software, check if your access point is set to the stealth mode, i.e., set not to broadcast its SSID, or is set to reject clients whose SSID is set to ANY. If so, click Manual Setup and enter the access point's SSID in SSID. For details, refer to "5.1 The Access Points dialog box is displayed during setup" on page 3. 2.1 The target access point is not detected (continued) • The wireless channel to be used may be limited depending on wireless network devices installed in the computer. Confirm the wireless channels available for the network device. For details, refer to the manual provided with your computer or your wireless network device. Make sure that the channel set to the access point is valid to communicate with the computer, confirmed above. If not, change the channel set to the access point. • If MAC address filtering is enabled, we recommend that you register the machine's MAC address to the access point before entering setup. To confirm the MAC address of the machine, refer to "About Network Communication" - "Troubleshooting" in the on-screen manual: Advanced Guide. • If the access point's IP address filtering is enabled, disable it during setup. After setup is complete, turn the IP filtering feature back on. • If Client-to-Client Blocking is enabled, an access point may be capable of blocking all direct transmission among clients associated to it. If such feature is enabled, disable this feature while using the machine. 2.2 Cannot connect to the target access point • Refer to "1 Connection checklist" on page 1 and make sure there is no problem. • Confirm the network name/SSID of the target access point and set the machine to use the identi- cal network name/SSID. If the network name/SSID is different in the machine and the access point, the machine cannot connect to the access point. For details, refer to "5.1 The Access Points dialog box is displayed during setup" on page 3. • This machine does not support WPA/WPA2-Enterprise. When you select an access point set to use WPA/WPA2-Enterprise, it is grayed out and cannot be set up. • Make sure that the machine and the access point can communicate with each other under this setting. When encryption is set to the access point, set up the encryption of the machine to match the settings of the access point. If the WEP/WPA/WPA2 (encryption key) is different in the machine and the access point, the machine cannot communicate with the access point. For details, refer to "3.2 How to set a WEP/WPA/WPA2 key" on page 2. 2.3 Using the machine in a multiple access point setup Confirm the following the access point to be used can communicate with the machine and the computer. Windows XP may automatically connect to an unintended access point. Follow the steps below to make your access point the highest priority. a Select Start and Connect To. b Right click Wireless Network Connection and select Properties. c Click Wireless Networks tab and confirm that Use Windows to configure my wireless net- work settings is checked. d Confirm that the target access point is displayed in the Preferred networks list. If the access point is not set to the top in the list, select and move the access point to the top of the list using the Move up. If multiple networks are available when using Macintosh, select System Preferences, select Network, select AirPort and click Advanced (Mac OS X v.10.4.x/v.10.3.9: select Network Port Configuration), then change the priority of the network name that you want to use. If the network name is not set to the highest priority, select and move it to the top of the list (the highest priority).
