Hi, i’ve got 3 switches in a daisy-chaining configuration, devices connected to them are disappearing after some days, any idea of what can get wrong?

First Switch (Edimax GS-1005BE):

Personal Computer: 2.5 Gbit/s pci-e to ethernet card with jumbo frames 9000, OS: Windows 11
Internet LAN Routeur: 2.5 Gbit/s, Internet connection, some devices like TV, amplifier are connected on it by RJ-45.

Second Switch (Edimax GS-1005BE):

Macbook Pro: 1 Gbit/s

Third Switch

Printer: 1 Gbit/s
NAS Synology: 2.5 Gbit/s usb to ethernet adapter with jumbo frames 9000

I just need to disconnect/connect switches to see every device again.
