However, setting up Wi-Fi on this printer often raises questions: the indicator light blinks abnormally, the network fails to find the device, or the drivers refuse to install. In this article, we'll look into these issues. all connection methods — from standard WPS to manual parameter entry, and we'll also explain how to avoid common errors that cause the printer to "lose" the network after rebooting.

Feature of the model SCX-3405W in that it only supports networks 2.4 GHz — this is important to consider when choosing a router. If your router operates on two bands, you'll have to temporarily disable it. 5 GHz or create a separate network for the device. We will also cover the setup in detail via printer web interface (yes, it has its own IP address!) and we'll explain why a factory reset sometimes helps—despite the manual not mentioning it.

For your convenience, we've broken the process down into steps: from preparing your equipment to printing a test page. If you've already tried setting up Wi-Fi and encountered an error (for example, Wi-Fi Direct is not available or Failed to connect to the network), skip the first steps and go straight to the section TroubleshootingThere you will find unique solutions for the SCX-3405W, which are not found in standard manuals—for example, how to bypass MAC address blocking or what to do if the printer "sees" the network but does not connect.

Preparation: What to do before setting up Wi-Fi

Before you begin connecting, please ensure three key conditions are met:

• 🔌 The printer is plugged into the outlet. and the power indicator is green (not blinking!). If the light is orange, the device is in power saving mode. Press the power button.
