5. Specifically enable “Maintain Network Connection During Sleep” if available
6. Save your changes and restart the printer

These adjustments help ensure your printer maintains its network connection even in lower-power states.

Solution 4: Update Router Firmware and Settings

Your router might be contributing to your printer connectivity issues:

1. Access your router’s admin panel (typically by entering 192.168.1.1 or 192.168.0.1 in a browser)
2. Update the router’s firmware to the latest version
3. Increase the DHCP lease time to maximum (often found under DHCP settings)
4. Disable “AP isolation” or “client isolation” if enabled
5. If possible, create a MAC address reservation for your printer
6. Consider enabling the “DHCP persistent” option if available

These router adjustments create a more printer-friendly network environment that facilitates reliable reconnections.

Solution 5: Optimize Wireless Signal Strength

Poor signal quality can prevent successful reconnection:

1. Position your printer closer to the router if possible
2. Remove physical obstacles between the printer and router
3. Keep the printer away from potential interference sources (microwaves, cordless phones)
4. Consider using a Wi-Fi extender if distance is a persistent issue
5. If your router supports dual-band (2.4GHz and 5GHz), try connecting your printer to the 2.4GHz band, which has better range and wall penetration

Stronger signal integrity significantly improves your printer’s ability to maintain and reestablish connections.

Solution 6: Reinstall Printer Software

Sometimes the issue lies with your computer’s printer software:

1. Uninstall all existing printer software from your computer
2. Download the latest full-feature driver package from the manufacturer
3. Temporarily disable antivirus software during installation
4. Follow the manufacturer’s installation procedure precisely
5. When prompted for connection type, select wireless network
6. Allow the setup process to discover and configure your printer

Fresh software installation often resolves underlying communication problems between your computer and printer.

Solution 7: Configure WPS or Direct Wireless Setup

Using Wi-Fi Protected Setup (WPS) or direct wireless can improve connection stability:

1. Locate the WPS button on both your printer and router
2. Press the WPS button on your router first
3. Within 2 minutes, press the WPS button on your printer
4. Wait for the connection to establish (typically indicated by a solid Wi-Fi light)
5. If your printer supports direct wireless connection, consider this option as a backup solution

This method establishes a more direct and often more stable connection between devices.
