ASSIGN STATIC IP ADDRESSES TO ALL DEVICES IN THE NETWORK
Most wireless networks use a DHCP server (Dynamic Host Configuration Protocol) built in to the wireless router to assign IP addresses to clients on the wireless network. DHCP addresses are assigned when they are needed, as when a new device is added to the wireless network or when it is powered on. Wireless devices must send a request to the router, and receive an IP address in response so they can function on the network. Because the wireless router performs many other tasks besides assigning addresses, it sometimes does not respond quickly enough with an address. The requesting device sometimes gives up before it receives an address.
Try assigning static IP addresses to the devices in your network to resolve this issue.
To assign a static IP address to the printer:
1Complete the wireless setup, allowing the printer to receive a DHCP address from a DHCP server on the network.
2Print a network setup page to see what IP address is currently assigned to the printer.
3Open a Web browser and then type the printer IP address in the address field. Press Enter.
4Click Configuration > TCP/IP > Set static IP address.
5In the Address field, type the IP address you want to assign to the printer, and then click Submit.
Confirm that the IP address is updated by typing the static IP address in the browser address field and checking to see if the printer Web page reloads. For more information on assigning static IP addresses, see the documentation that came with your router and operating system.
CHECK FOR KNOWN ISSUES WITH THE ACCESS POINT
Some wireless routers have documented defects that were identified and resolved by the manufacturers. Visit the company Web site of the router manufacturer. Check for firmware updates and other advice from the manufacturer. See the documentation that came with your wireless router if you are not sure how to reach the manufacturer Web site.
CHECK FOR WIRELESS NETWORK ADAPTER UPDATES
If you are having trouble printing from one particular computer, then check the Web site of the manufacturer of the wireless network adapter card in that computer. It is possible that there is an updated driver available that could resolve the issue.
CHANGE ALL NETWORK DEVICES TO THE SAME TYPE
While it is possible to successfully mix 802.11b, 802.11g, and 802.11n devices on the same wireless network, the faster devices will sometimes prevent the slower devices from communicating.
Try turning on only the network devices of the same type and see if network communications improve. If this solves the problem, then you may want to upgrade your older devices with newer wireless network adapters.
PURCHASE A NEW ROUTER
If your router is several years old, then it may not be fully compatible with the newer wireless devices on your network. Consider purchasing a newer router that is fully compliant with the 802.11 IEEE specifications.
