Intermittent weak internet signal that went away after I cleared out some videos

I have had a wired floodlight cam for two+ years. Same internet provider, same router, same position in the house. This last week, I kept getting a "weak internet" signal, though nothing had been moved, It might show weak in the am, but ok in the pm or vice versa. This is a second home, so no one was wandering around messing with furniture. After I deleted a bunch of videos ,I no longer get "weak internet" signal (am or pm). Mind you, this was maybe 20 30 sec videos collected over a two week period, which I don't consider a lot, but perhaps Ring/Amazon does?I am at the house this week and was trying to decide whether to leave well enough alone (since the problem has vanished) or just reboot in principle. Anyone else experience this and/or have some insights to share?Thanks
