Floodlight Pro Video Playback is Double Speed

I have 3 floodlight cameras and one doorbell camera at different points on my house and varying distances from my home router. For 2 years they've all worked relatively fine but a few months ago one camera started exhibiting issues with video quality and playback speed. The RSSI is consistently in the 40's (currently RSSI-46) but when I watch a live event, the playback speed is as though I've somehow pushed fast forward. To be clear, I am not mistaking this issue for snapshot views. My camera picks up motion, for example, when I am mowing the lawn, and when I watch it back, it is displayed at twice the speed even though the seconds on the video are incrementing at a normal rate. No other camera has this issue and the camera isn't in a position where it would be exposed to the elements. I've rebooted the camera several times, checked for updates, stood on a ladder to hard reset it, all to no avail. I've seen this asked and answered several times and I keep seeing it dismissed as poor network strength or otherwise, but as I said I have several cameras, at least one that's much farther from my router, and they have never experienced a similar issue. There was an event the other day and all that I could catch was a glimpse of something leaving the frame because I could not slow down the video.
