Think of bands like little elastic springs that hate sharp bends and tiny cuts. Every time you loop one around a skinny hook or a rough edge you create a tight bend that concentrates stress and starts a tear. Use an anchor with a bigger diameter or wrap a towel to increase the bend radius. Keep stretch under about two times length rather than three or more because the strain shoots up fast. Cold spaces make latex stiffer so warm up the band with light reps first, and keep sunscreen and bug spray off them since oils and solvents accelerate cracking.
The lease tip is spot on; a long lease plus no nightly reboots usually stops the mass drop-offs. I'd also disable the "smart" Wi-Fi tweaks that trip cheap IoT radios: 802.11r/k/v roaming airtime fairness/target wake time, and any auto-optimization, and keep DTIM at 1-2 with 20 MHz on a fixed 2.4 channel. If you've raised minimum data rates, allow the legacy 2.4 rates again-older ESP-based plugs won't stay associated otherwise.
