Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- on this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). You can find the DHCP range of the router using its internal settings page or in its manual. Use the CD that came with your router or type the router's IP address (ends in .1) into a browser.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway and first DNS. Leave the second one blank. <<< The DNS could be your problem. If this does not work, try Google's DNS 8.8.8.8
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.
