Thank you for your response,
Yes, your HP Envy 4520 has a wireless module (chip) responsible for connecting to Wi-Fi, and it can fail over time. However, before assuming a hardware failure, try these troubleshooting steps to confirm:
Check if the Printer’s Wi-Fi is Working
- Activate Wi-Fi Direct:
- On the printer, go to Setup > Network Setup > Wi-Fi Direct > Turn On.
- Connect your iPad directly to the printer’s Wi-Fi Direct network (e.g., HP-Print-XX-4520).
- Try printing.
- If Wi-Fi Direct works but your home Wi-Fi does not, your printer’s wireless module may still be functional but having trouble with the router.
Reset the Printer to Factory Defaults
- Go to Setup > Printer Maintenance > Restore Defaults.
- Select Restore Factory Defaults and confirm.
- Set up Wi-Fi again using Wireless Setup Wizard.
Check Router Settings
- Ensure your Wi-Fi is set to 2.4GHz (HP Envy 4520 does not support 5GHz).
- Disable IPv6 in router settings (some printers have issues with IPv6).
- If possible, try connecting the printer to a different Wi-Fi network to test.
Test a USB Connection
- If USB works but Wi-Fi still fails, the wireless module may be faulty.
- If Wi-Fi doesn’t work even after a factory reset, the Wi-Fi chip may be damaged.
