How to Connect an HP DeskJet 3635 Printer to Wi-Fi: 3 Proven Methods + Troubleshooting

Multifunctional device HP DeskJet 3635 — a popular model for home and small offices, combining compact size with wireless capabilities. However, connecting to Wi-Fi often raises questions: the printer may not detect the network, or it may not accept the password, or the indicator light may blink endlessly. This article will help you understand all the nuances, from choosing a connection method to troubleshooting common errors.

We will look at three official methods: through WPS button on the router, using printer control panels and through the application HP SmartEach option is suitable for different situations—for example, WPS is convenient when the device doesn't have a display, while HP Smart is useful for remote setup from a smartphone. You'll also learn how to check if the connection is successful and what to do if the printer stubbornly refuses to connect to the network.

Important: If your DeskJet 3635 If you've previously connected to a different Wi-Fi network, reset your network settings before setting up. This will prevent conflicts between the old and new settings. Reset instructions are in the relevant section of this article.

• 📶 The router is turned on and distributing Wi-Fi.Check that the wireless network indicator on your router is lit and not blinking. If you're using a dual-band router (2.4 GHz + 5 GHz), the printer HP 3635 supports only 2.4 GHz.
• 🔒 You know the network name (SSID) and passwordIf the network is hidden, temporarily make it visible in the router settings. The password must be entered correctly—the printer is case-sensitive and character-sensitive.
• 🖨️ The printer is turned on and ready for setup.There should be no red error indicators on the front panel. If the light Wi-Fi blinking blue - the device is already in network search mode.
• 📱 Do you have a smartphone or computer? for alternative connection methods (via HP Smart or web interface).

Pay special attention router operating modeSome modern routers use it by default. WPA3 or mixed mode WPA2/WPA3. HP DeskJet 3635 may not support WPA3 - in this case, in the router settings, select only WPA2-PSK (AES).

⚠️ Attention: If your router is set to automatically select a Wi-Fi channel, temporarily set it manually (for example, to channel 6 or 11). This will help avoid connection issues related to channel switching.
