GL-AR150 Connected without internet

set up my router and private network using “repeater” option. i do not have a modem and get wifi from xfinitywifi. Worked well for 2 months. A few days ago I lost the connection to the internet. It shows in the list of available networks but states I am connected without internet. unable to connect with internet on any devices through the GL-AR150. reset for 3 seconds of no help.
How do i get online?
