Flood light and Spot light cameras stutter and stop

I have 11 cameras working. The Flood and Spot light cameras are the only ones that start playback, but freeze after a few seconds. Usually about 10 seconds into a 1 minute recording. The spot light camera is really bad. Rebooting router, rebooting cameras and no difference. The wifi signal is fine. The spot light camera is 2 yrs old and flood light camera is one year old. Any help is appreciated.

Hi @turbobuick86. What is the RSSI for these devices? Have you tried using a different WiFi channel? You can use this information here to change them.
