Improved 8 Port Gigabit Switches for Internet Access.
Improved 8 Port Gigabit Switches for Internet Access.

I restart the switches whenever the Internet stops functioning on the devices inside each office.
I refer to "odffices" informally. My partner and I frequently work remotely, each having our own computers at home and in the office.
Here is a simplified view of the network layout.
TP-Link AX11000[LAN Port] ----> TP-Link SG1008D[LAN Port] ----> TRENDnet TEG-S82g[LAN Port]
As observed, they are connected in a chain.
I accessed the AX11000 and reviewed the logs.
The following entries appear:

I might have solved the issue. I examined the wiring and noticed the TP-Link switch requires a 9V 0.85A adapter. I used a 12V 1A one instead. After checking my power adapter box, I found the correct TP-Link adapter and connected it. Everything seems to function properly, though I’m unsure if the higher voltage might have led to instability.
The voltage and amperage values are probably within acceptable ranges for the switch. The incorrect adapter might be responsible.

You can also look up similar resources online for further understanding.
It’s best to avoid damage, as overheating is harmful to electronics. Reboots may help the components cool, but according to @USAFRet, another factor might be at play based on the two-week pattern.
You may need to wait a bit longer to confirm the issue is resolved.
I have some ideas, though they’re just speculation at this point.
