PC network disconnects at 4:30pm everyday

Question

Hi,

I was wondering if anyone has ever come across something like that? The system doesn't turn off, but the connection just disconnects at 4:30pm each day. Would be good if someone can give me some pointers on this.

Cheers

Hello Sarpong, Othniel,

I hope the information above is helpful.

If you can provide more details, it might be easier to pinpoint the issue.

For instance, what type of connection this is, whether you’re connecting via Ethernet or Wi-Fi, if this is happening on one machine or multiple devices, or if there’s any particular network equipment involved and so on.

Here are a few areas to investigate:

1. Scheduled Tasks or Maintenance:

Check if there are any scheduled tasks (either on your local machine, a server, or even a router) that might be restarting network services or reassigning network settings around that time.  

If you’re on a managed network (like in an office), see if the IT department has maintenance windows or automated scripts that could be interrupting connections.

2. Router or Modem Settings:

Some routers or modems have scheduled reboots or firmware updates. Verify if your device has been set to restart or refresh its connection at that time.  

3. External Factors:  

If this connection is part of a VPN or remote access setup, check if there’s an idle timeout or scheduled disconnection policy on the VPN server or gateway. For example, does something like an automated power management system (e.g., energy-saving features that kick in after working hours) on your networking hardware or switch gear show up around 4:30 pm?

4. Logs and Monitoring:  

Examine system and network logs (both on the device and on any network hardware like routers or firewalls) for entries around 4:30 pm that might indicate why the connection is being terminated.

5. Software or Firmware issue:

Ensure that all network hardware and client software are updated.  Firmware issue or misconfigured network drivers may lead to consistent connectivity drops.

6. Test and Isolate:

Try replicating the setup on another system to see if the issue persists. This may help narrow whether it’s a local issue on one machine or something more in the entire network.  

Temporarily bypass any devices that might be causing the issue (for example, extra routers or firewalls) to see if that helps.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.
