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
