Lexmark Printer Not Connecting to WiFi: Here’s How to Fix It

A Lexmark printer not connecting to WiFi is not uncommon. The problem can occur if you have changed your Wi-Fi router, updated your passwords, or installed Windows. A corrupted printer driver can also be responsible.

If your printer keeps going offline and won't connect to WiFi even after trying your best, we have some tried-and-tested solutions for you. 

In some cases, a quick restart may work; at other times, reinstalling drivers or clearing the print spooler is the reliable method. We’ll discuss the best possible ways to connect your Lexmark printer to WiFi on both Windows and Mac systems. But, before that, let’s understand the major reasons behind this glitch. 

Top Reasons for Lexmark Printer Not Connecting to WiFi

If your Lexmark printer refuses to connect to your WiFi network, these may be the possible reasons: 

• Wrong Password/SSID: You may have entered the wrong network password or chosen the wrong network name (SSID).
• Active Adapter Setting: The active adapter in the printer settings may not be set to “Auto” or “Wireless.”
• Wrong Frequency Band: Most Lexmark printers support 2.4 GHz, so they may not connect if the router is set to 5 GHz.
• Active Ethernet Cable: Plugging an Ethernet cable into the printer may disable the Wi-Fi adapter.
• Poor Signal or Interference: Physical obstructions, walls, or interference from other electronic devices.

Checklist to Keep in Mind Before Troubleshooting

It is important to confirm the following before you get on with the fixes: 

• Power & Status: Check that your printer, WiFi router, and PC are all fully powered on and connected to power
• Same Network: Confirm your computer/mobile device and the printer are on the same Wi-Fi network.
• Disable VPN: Sometimes, VPN can interfere with the Printer-to-WiFi connection. So, you must turn it off for a while before you get started. 
• Network Name & Password: Check that you have the correct SSID and password. Note that these are case-sensitive.
