You can choose any strategy from a variety of approaches to configure your brand-new Linksys Velop device. But, for an easy and quick Linksys Velop MX4200 setup, you must use the WPS method. So, if your new Velop supports a WPS button, try this method. However, there are two other procedures that entail slightly more difficult steps: web-based and WiFi app approaches. So, for the first method, plug the Velop into a power socket using a power cable. Then, confirm the WPS compatibility of your existing modem and hit the WPS button from it. When there is a blinking LED on the modem, press the same button from the Velop setup. Wait to get a blinking light on it and let both devices attach together or complete the setup. You will notice steady lights on both devices within a short period of time, signifying that the setup is finished.
