I just changed to the Liberty 50 plan with the new modem/router combo. Please tell me why I have to repeatedly sign in to this network during the day? About every 30 minutes there is a pop up on my phone screen asking me to “choose a network “ and I have to go through the process of re-connecting and typing in the password. It also says that I am getting “guest” access to an “unsecured “ network. Is there a way to configure the router so it won’t keep disconnecting?
