How to Connect a Lexmark Printer to WiFi (Every Method, Explained Properly)

The fastest way to connect a Lexmark printer to WiFi is through the control panel's Wireless Setup Wizard: tap Settings > Network/Ports > Wireless > Set up now, pick your network from the list, type the password, and confirm. Most Lexmark laser printers the MB2338adw, MC3224dwe, B2236dw, MS312dn, and similar models, connect within 60-90 seconds using this method, provided the printer's firmware is current and it's sitting on a 2.4GHz signal.

If that sentence answered your question, you're done. If you've already tried it and the printer still won't show up on the network, keep reading - the fix is usually one of five specific things, and they're covered further down.

Before You Touch the Control Panel

Three things trip up more Lexmark setups than anything else, and checking them first saves you from restarting the wizard five times.

Your router needs to be broadcasting 2.4GHz. Nearly every Lexmark printer, including newer color laser models like the CX522, only has a single-band 2.4GHz radio. If your router is set to 5GHz-only or has merged both bands under one network name (common on mesh systems like eero and Google Nest WiFi), the printer simply won't see the network in its scan list. Log into your router and confirm a separate 2.4GHz SSID exists, even temporarily.

Firmware age matters more than people assume. Lexmark's own setup documentation for its network-connected printers explicitly recommends updating firmware before running the wireless wizard, because older firmware versions have known bugs in the WiFi scanning routine that cause the network list to come back empty or stall on "Searching for networks." You can check this from Settings > Device > About This Printer > Check for Updates - do it before you do anything else.

Know your exact password, not the one you think you remember. WiFi passwords are case-sensitive on the printer's touch keypad, and a surprising number of "connection failed" errors turn out to be a lowercase L typed where an uppercase I belongs. If your ISP-installed router, check the label on the device itself or the setup sheet left by the installer - that's the actual password, not whatever you set up on your phone's saved WiFi list years ago.

Method 1: Wireless Setup Wizard (Control Panel)

This is the default method on any Lexmark printer with a touchscreen or LCD panel, and it's the one Lexmark documentation leads with for a reason: it doesn't require a computer, a cable, or an app.

1. On the printer's home screen, tap Settings.

2. Go to Network/Ports > Wireless.

3. Select Set up now (some models label this Wireless Setup Wizard).

4. Choose your network's SSID from the scanned list.

5. Enter the WiFi password on the touch keyboard and select Done.

6. Wait for the confirmation screen - the printer will show a signal-strength icon once connected.

On a handful of models, particularly the CX series, the printer will restart automatically after saving the settings. That's expected behavior, not a fault; let it finish the reboot cycle before printing a test page.

A detail most guides skip: if the network list only shows a handful of networks or seems to be missing yours, don't back out and retry immediately. The printer's WiFi radio needs a few seconds to complete a full scan cycle. Backing out and re-entering the menu repeatedly can actually reset the scan and make it take longer, not shorter.

Method 2: WPS (Push Button or PIN)

WPS skips the typing entirely, which is genuinely useful if your WiFi password is long or contains characters that are painful to enter on a printer keypad.

(Note: For models without a touchscreen, several of Lexmark's older monochrome laser printers fall into this category; there's no menu to tap through. Look for a physical Network or WiFi button on the machine itself, or use the arrow keys on the control panel to navigate to the Network menu and select WPS from there.)

Push Button Method:

1. On the printer, go to Settings > Network/Ports > Wireless > Wi-Fi Protected Setup > Start Push Button Method.
2. Within two minutes, press the physical WPS button on your router.
3. The printer connects automatically once it detects the router's WPS signal.

PIN Method (use this if your router doesn't have a physical WPS button but supports WPS through its admin panel):

1. Navigate to Settings > Network/Ports > Wireless > Wi-Fi Protected Setup > Start PIN Method.
2. The printer displays an eight-digit PIN.
3. Log into your router's admin console, find the WPS section, and enter that PIN.
4. Save the settings and let the router push the connection through.

One caveat worth knowing: some enterprise-grade and mesh routers disable WPS entirely by default because of a well-documented brute-force vulnerability in the PIN method. If WPS doesn't appear as an option on your router at all, that's not a printer problem - it's a router setting, and you'll want to use the setup wizard instead.

Method 3: Lexmark Print App (Mobile Setup)

If the printer's control panel feels fiddly, or you'd rather do the whole thing from your phone, Lexmark's mobile app handles the pairing for you.

1. Install the Lexmark Print app (Lexmark Mobile Assistant on older listings) from the App Store or Google Play.
2. On the printer, go to Settings > Network/Ports > Wireless > Setup Using Mobile App, and note the Printer ID shown on screen.
3. Open the app, accept the terms of use, and grant any permissions it asks for (location access is required on Android for WiFi scanning — this is an OS requirement, not a Lexmark one).
4. Enter the Printer ID to pair with the device.
5. Select your WiFi network in the app, enter the password, and confirm.

This method is worth defaulting to for anyone setting up a printer in an office where several people will need to configure their own devices afterward — the app also handles adding the printer to your phone or tablet for direct mobile printing in the same flow, so you're not doing wireless setup and mobile pairing as two separate jobs.

Method 4: USB Cable + Lexmark Printer Installer (No Working Display)

If the printer's screen is unresponsive, or you just prefer doing setup from a PC, this method uses a temporary USB connection to hand over the WiFi credentials - the cable comes out once setup finishes.

1. Download the Lexmark Printer Installer for your model from support.lexmark.com/drivers.
2. Run the installer and select a wireless connection when prompted.
3. Connect the printer to your computer via USB when asked.
4. Follow the on-screen prompts and enter your WiFi network and password.
5. Once the installer confirms the printer is on the network, disconnect the USB cable.

This is also the most reliable fallback when the wireless wizard keeps failing on the printer itself because the credentials are being pushed from the computer rather than typed on a touchscreen - it sidesteps keypad typos and half-finished network scans entirely.

Method 5: Wi-Fi Direct (Printing Without a Router)

Wi-Fi Direct isn't a way to get the printer onto your home network - it turns the printer itself into a small wireless access point that nearby devices can connect to directly. It's genuinely useful in two situations: your router is down, or you're printing somewhere with no WiFi infrastructure at all (a job site, a pop-up event).

1. On the printer: Settings > Network/Ports > Wireless > Enable Wi-Fi Direct.
2. To find the shared password: Settings > Network/Ports > Wi-Fi Direct > Show PSK on Setup Page.
3. On your phone or laptop, open WiFi settings and look for a network named DIRECT-xy-[your printer name] (the "xy" is two random characters Lexmark appends automatically).
4. Connect using the PSK (preshared key) shown on the printer.

Keep in mind Wi-Fi Direct connects one device at a time in most configurations, and it doesn't give the printer internet access - it's a local-only link between the printer and whatever's connected to it.

Troubleshooting: When None of This Works

Printer connects, then drops offline again within minutes. This is almost always a router power-saving setting, not a printer fault. Some routers deprioritize or briefly disconnect idle devices to save bandwidth. Check your router for an option like "AP Isolation" or aggressive client timeout settings, and exclude the printer if possible.

5GHz network isn't showing up in the scan list at all. That's expected on the majority of Lexmark models - most only support 2.4GHz. This isn't a bug to fix; you need a 2.4GHz SSID available.

Wizard says "connection failed" immediately after entering the password. Re-check for autocorrect-style substitutions from muscle memory (typing a WiFi password you use elsewhere), and confirm caps lock status on the touch keyboard - it's easy to miss on a small screen.

Printer connects to WiFi but won't show up on the computer. This is a discovery issue, not a WiFi issue. The printer has an IP address, but the computer isn't finding it. Print a network setup page from the printer (Settings > Reports > Network Setup Page) to confirm the IP address, then add the printer manually on your computer using that IP rather than relying on automatic discovery, which can be blocked by network isolation settings on guest networks or some mesh systems. One thing worth doing right away: set a static IP or a DHCP reservation for the printer in your router settings. Without it, the IP address you just used is only temporary - the next router reboot or lease renewal can hand the printer a different address, and your computer will suddenly "lose" a printer that never actually went offline.

Setup worked once, then the printer needed re-pairing after a router replacement or reset. WiFi credentials are tied to the SSID and password combination, not the router hardware. Any time you replace your router or factory-reset it, even keeping the same network name, you'll need to run the wireless setup again on the printer.

What to Do After the Printer Connects

Once the printer shows connected on its display, print a test page directly from the control panel first - this confirms the printer itself has a valid connection before you troubleshoot anything on the computer side. From there, install the correct driver from support.lexmark.com/drivers using your specific model number rather than a generic "universal" download, since print quality settings and duplexing options vary between Lexmark's laser and multifunction lines. If you're setting up scanning as well as printing, you'll need to add the printer separately in your OS's scanner settings even after print setup is complete - the two aren't handled by the same driver pairing on every Lexmark model.
