Occasional Ethernet drops occur
Occasional Ethernet drops occur
Your PC has been having occasional disconnections, mostly at night for a few seconds. You've tried several fixes: upgraded the Ethernet card, reinstalled drivers, cleaned the cables with alcohol, and even used Wi-Fi while disconnecting. Since the cable seems solid and replacing it is difficult, let's explore other possibilities to rule out hidden issues.
This indicates it isn't your account. The standard hours apply per the ISP...
the problem seems to happen only when the PC is connected, not when it's off. The connection might be unstable or there could be an issue with the cable itself. Trying different ports on the router didn't resolve the issue.
I’d connect another machine and check if the issue persists on both devices. If it doesn’t, you should reinstall Windows. If it does, swap out the router.
It wouldn't be safe to jump to conclusions without more information. These steps rely on assumptions that need verification.
