If your HP ENVY 5660 not connecting to wifi, you're not alone. This all-in-one inkjet printer relies on a stable wireless connection for printing from multiple devices, and connectivity drops can halt your workflow. Whether you're seeing "Printer Offline" errors, failed setup attempts, or intermittent disconnections, this printer repair guide walks you through proven troubleshooting steps to restore your wireless connection. Our printer support team has resolved thousands of similar cases, and these methods work for the ENVY 5660 running on both 2.4GHz and dual-band networks.
Initial Network and Printer Checks
Before diving into advanced troubleshooting, verify that your network environment supports reliable printer communication. The HP ENVY 5660 requires a 2.4GHz Wi-Fi band and cannot connect to enterprise-level security protocols like WPA3-Enterprise.
1
Verify Router Band and Signal Strength: Access your router's admin panel (typically 192.168.1.1 or 192.168.0.1) and confirm the 2.4GHz band is enabled with SSID broadcast active. The ENVY 5660 does not support 5GHz-only networks. Position the printer within 30 feet of the router, avoiding microwave ovens, cordless phones, and thick walls that degrade signal. Check that your router firmware is updated—outdated firmware commonly causes HP ENVY 5660 not connecting to wifi issues.
2
Run the Wireless Network Test from Printer Control Panel: On the ENVY 5660 touchscreen, press the Settings icon (gear symbol), navigate to "Network Setup" > "Wireless Settings" > "Print Wireless Test Report." This diagnostic shows signal strength, detected network name, and specific error codes. Note any "FAIL" results—particularly for connectivity, quality, or authentication tests—as these pinpoint where to focus your fix printer efforts.
3
Restore Network Defaults and Reconfigure: From the printer's Settings menu, select "Network Setup" > "Restore Network Defaults" to clear corrupted wireless profiles. After the printer restarts, use "Wireless Setup Wizard" to reconnect. When prompted, enter your Wi-Fi password carefully—the ENVY 5660's touchscreen can misregister characters. For easier entry, use the HP Smart app on your phone which transfers credentials automatically via Bluetooth during setup.
Advanced Troubleshooting for Persistent Connection Failures
When basic steps don't resolve HP ENVY 5660 not connecting to wifi, deeper network configuration and software issues are likely at play. These advanced methods address DHCP conflicts, driver corruption, and router compatibility problems.
4
Assign a Static IP Address: DHCP lease conflicts cause recurring disconnections. On the printer's Wireless Test Report, note the MAC address. Access your router's DHCP reservation settings and assign a fixed IP address (e.g., 192.168.1.150) to this MAC. On the ENVY 5660, navigate to Settings > Network Setup > Advanced Settings > IP Settings > Manual, then enter: IP Address (your reserved address), Subnet Mask (typically 255.255.255.0), and Default Gateway (your router's IP). This eliminates IP conflicts that trigger offline states.
5
Update Firmware and Reinstall Printer Drivers: Outdated firmware on the ENVY 5660 creates compatibility gaps with modern routers. Connect the printer temporarily via USB to your computer, then visit HP's support site and download the latest firmware update utility. Simultaneously, remove existing printer software from Windows (Settings > Devices > Printers & Scanners > Remove) or Mac (System Preferences > Printers & Scanners > minus button). Reinstall using HP Smart or the full feature driver package—basic drivers often lack robust wireless management protocols essential for stable connectivity.
6
Configure Router for Printer Compatibility: Log into your router and apply these settings: Set wireless mode to 802.11b/g/n (not ax/6 only), enable WMM if available, disable AP Isolation/Client Isolation, set channel width to 20MHz on 2.4GHz for stability, and use channels 1, 6, or 11 to minimize interference. If your router has band steering or "Smart Connect," disable it—these features force 5GHz connections that the ENVY 5660 cannot use. After changes, reboot both router and printer before attempting reconnection.
⚠️ Important: Do not perform a factory reset on your HP ENVY 5660 unless specifically directed by HP tech support, as this erases all settings including scanner calibration data. Also, avoid using WPS push-button setup on routers with WPS vulnerabilities—manual configuration with WPA2-AES encryption is more secure and reliable for this model.

Why does my HP ENVY 5660 keep disconnecting from Wi-Fi after working fine?
Intermittent disconnections typically stem from DHCP lease expiration, router channel congestion, or firmware mismatches. Assign a static IP address to your printer and update both printer and router firmware. Also check if your router recently switched to a crowded channel—use a Wi-Fi analyzer app to identify less congested channels 1, 6, or 11.
Can I connect my HP ENVY 5660 to a 5GHz network?
No. The HP ENVY 5660 only supports 2.4GHz wireless networks. If your router broadcasts a single SSID for both bands (band steering), disable this feature or create a separate 2.4GHz-only network name. Attempting 5GHz connection will result in repeated failed setup attempts or the printer not detecting your network at all.
What does "Enter the WPS PIN for your router" mean during setup?
This prompt appears when using Wi-Fi Protected Setup. The PIN should be printed on a label on your router (not the printer). However, due to known security vulnerabilities in WPS, we recommend using the Wireless Setup Wizard with manual password entry instead. If you must use WPS, use the push-button method rather than PIN entry.
