Sudden Signal Change

So I am at a loss here, Network geek by day. I have a doorbell 2 that up untill wednesday has never given me an issue. Noticed drop off to almost no motion events. Upon further review live view says "Poor Connection" Netgear night hawk literally 6-7 ft away, stand at the door bell with Phone, lappy etc full wifi connection with low pings. Door bell reportds RSSI 56. I restarted router, modem and did a hard reset of door bell. Any help?Jeff
