Key notes

The Epson WF-3640 is a printer that you can print wirelessly with by connecting it with yourWi-Finetwork.

However, some WF-3640 users can encounter wireless issues during printer setup or when they try to print with a wireless connection.

In either case, the printer usually can’t connect toWi-Fi.

Why is my Epson printer not connecting to Wi-Fi?

Some users might see anEpson PrinterWi-FiSetup Failedmessage when trying to set up the WF-3640 for wirelessprinting.

The wireless setup might fail due to users entering invalid SSID or password details. That issue can also arise due to network settings conflicts or droppedWi-Ficonnections.

Some WF-3640 users, who have already set up the printer, might see aPrinter is offlinemessage when they try to print wirelessly.

This wirelessprintingerror can be a printer driver issue. However, firewalls can also block Epson wireless printer connections.

How do I get my Epson printer to print wirelessly?

1. Turn off Windows Defender Firewall

Users with third-party antivirus or firewall software should either disable or uninstall those utilities.

Right-click the system tray icons for third-party antivirus or firewall utilities to select disable settings that are often on their context menus. Temporarily disable thethird-party antivirusor firewall software.

Note:Users who need to fix theEpson PrinterWi-FiSetup Failederror shouldturn off firewallsbefore opening the WF-3640’s Epson Installer software to set up wirelessprinting.

2. Verify your SSID and password details

Double-check the SSID and password details you’re trying to establish aWi-Ficonnection with are valid.

To do that, look at the stickers on yourWi-Firouter. One sticker on your router should include your SSID network name and password needed to set up wirelessprintingfor your WF-3640.

3. Update drivers with a third-party solution

Outbyte Driver Updater can be a potential resolution for users who need to fix the WF-3640 printer offline error.

That driver updater software will quickly scan your PC and list hardware devices with outdated drivers. Outbyte Driver Updater’s scan report might show you that the WF-3640 needs a driver update.

If so, you’ll be able to click anUpdatebutton for the WF-3640 printer that will download its latest drivers. Outbyte Driver Updater Pro will automatically install the downloaded printer drivers when you click itsAutomatically Installoption.

5. Move your router closer to the WF-3640

If possible, try moving your router closer to your printer by plugging it in elsewhere.

If you really can’t set up the router in an alternative place, then consider moving your printer nearer.

Include the WF-3640 within the same room as the router (ideally about eight to 10 meters from it) if you can.
