You must first log in to complete your Linksys velop mx5300 setup via the setup page. The setup portal will ask for a login whether you select the WiFi app or the online interface. Thus, gathering the default login credentials is essential before proceeding with the configuration. Refer to the brief manual setup guide that came with the Velop to obtain the credentials. You can find out Velop's username, password, and other information by following that guide. Prior to beginning the setup, it will be helpful to take note of those credentials. However, you must change the default credentials after the setup to safeguard the network from hackers and unauthorized users.
