Hi i'm kind of new to technology and i'm not sure if this is the right place to go to.
I have a Samsung S4 that used to connect to my router with no problems but recently it keeps disconnecting after 2-5 minutes. I keep getting notifications such as "Your device has been disconnected from this network. Your session has timed out" and "Sign in is required" after opening my browser to sign in. I've been having this trouble for 3 days and cannot find anything online to help, i even checked my hub manager and still nothing.
