Why doesn’t my wireless printer show up on the router? The printer will not show up on the network. You can also “lose” a printer that has been operating satisfactorily on the same network for some time, although that is more likely to happen when you install a new printer. When you’re trying to solve a problem, you have to think about all the possible causes, which are simple, complex, and sometimes counterintuitive.
Wireless networks use a protocol language to communicate with each other, and each point has its own address. Routers provide network connectivity, such as wired and wireless infrastructure, as well as translating the information that each address sends and receives. Devices that do not appear on the network are either unable to find an address or have data that the router cannot understand.
Make sure you haven’t missed simple steps before trying more complex troubleshooting. Wireless routers and printers must be plugged in and powered on, as well as within the range of the wireless network. The presence of wall supports, or metal filing cabinets nearby can disrupt the Wi-Fi connection between the printer and router even when just a few feet apart. The wireless router needs to be able to locate the individual computers and vice versa in order to be up and running.

There is a simple but often overlooked way to turn wireless printing on and off on all wireless printers. The Wi-Fi connection can be accessed either via a button on the front of the printer (and LED indicator) or through the printer’s menu system. Additionally, you must enter the WEP (Wireless Encryption Protocol) key or WPA (Wi-Fi Protected Access) passphrase in the menu system to complete the network authentication. If you make a single mistake in any of these fields, the printer will not connect.
Why doesn’t my wireless printer show up on the router? The printers may not be wireless despite the router being wireless. It is possible that you assumed the printer was wireless, but it actually uses a USB or Ethernet port for network connectivity — or even a parallel port if it is an older model. Ensure that the printer is physically connected to the computer, and if necessary, swap the cable. It is possible that the router’s firewall is blocking the printer’s IP address as an unrecognized device; you may have to temporarily disable the firewall so that the printer is added to the router’s trusted device list, also known as a whitelist.
The printer’s device driver must be installed on each computer on the network if it is to send a job to it. The server-based network requires this driver to be installed on the server itself. A printer driver must be installed on each computer of a network connected through a router. Additionally, just like with the router, each computer’s firewall settings may block the printer as an unrecognized device, thus making it a potential threat.
Even though many printers and routers use standardized platforms, there are still a few combinations of devices that don’t communicate. An AirPrint printer (Apple) may have been attempted to be connected to a PC-based network, or vice versa. Although Wi-Fi N (802.11n) devices claim to be compatible with earlier Wi-Fi versions, such as 802.11a, 802.11b, and 802.11g, they might not always recognize them.
