The device will automatically exchange encryption keys. Once successfully connected, the Wi-Fi indicator on the printer will stop flashing and remain solid. This method doesn't require a smartphone, but the phone must be connected to the same network for subsequent printing.
What should I do if the WPS button is not found on my router?
If there is no physical button, log into the router's web interface (usually at 192.168.0.1 or 192.168.1.1), find the Wireless or Wi-Fi section, and activate the WPS function programmatically.
Setup via Wi-Fi Direct without a router
Function Wi-Fi Direct Allows you to create a direct connection between your phone and printer, bypassing the router. This is ideal if the internet is down or you're in a location without access to the main network. The printer then becomes an access point.
To activate, press the wireless button on the device's panel until the indicator light comes on. Then press the information button (the "i" symbol) or the key combination specified in the instructions to print a configuration report. The report will include the network name (e.g., HP-Print-xx-Laser MFP 135wr) and the default password.
Open your phone's Wi-Fi settings. Find your printer's name in the list of available networks. Enter the password found in the report or on the sticker on the back of the device. After connecting, your phone may warn you that there's no internet access. This is normal; agree to keep the connection.
| Parameter | Default value | Where to find |
|---|---|---|
| Network name (SSID) | HP-Print-xx-Model | Configuration report |
| Password | 12345678 | Sticker on the body |
| IP address | 192.168.223.1 | Configuration report |
| Protocol | Wi-Fi Direct | Panel indicator |

Troubleshooting connection issues
Even if you follow the correct steps, problems may still occur. Often, the problem lies in a hidden network SSID. If your router isn't broadcasting the network name, the printer won't be able to find it automatically. In this case, you'll need to use manual configuration through the device menu or temporarily enable broadcasting.
Another cause of errors is a MAC address filter on your router. If you have a whitelist of devices configured, the new printer will be blocked. You'll need to find the MFP's MAC address (indicated on the label or in the report) and add it to the allowed list on your router.
- 🔄 Restart your router and printer—this solves 80% of IP address assignment problems.
- 📵 Disable the VPN on your phone during setup, as it changes the traffic route.
- 🔒 Check the encryption type: your printer may not support the new WPA3 standard, try switching to WPA2.
If the HP Smart app says "Device not found," try temporarily switching your phone to mobile data, launching the app, and then turning Wi-Fi back on. Sometimes the app cache prevents the device status from being displayed correctly.
