Keep disconnecting / No live feed

I have been having issues over the last week where the ring 2 doorbell will not let me see live feed. I have reconnected the doorbell several times, have no issues at all with the WiFi (get 400-500mb downloads and 37mb uploads). I even purchased a WiFi extender just for the doorbell which was working until the last few days. I check device health and it says I have good connection with everything online. I am soo connected to the chime (not pro) which also shows good connection etc. Getting fed up with this at the moment. Any ideas?
