Fixing “pfSense keeps dropping WAN”

It can be quite annoying and inconvenient to network connectivity if pfSense’s WAN connection keeps failing. This could occur for a number of reasons, and troubleshooting may include a number of elements. Following are some typical reasons and solutions to assist us in identifying and fixing the problem:

1. Check WAN Interface Status

In order to check the WAN interface’s status, log in to the pfSense web interface and go to “Status” >> “Interfaces”. Make sure it is on and functioning. If the status is down, there may be a modem or ISP connectivity problem.

2. Inspect WAN Interface Settings

Check the IP configuration and gateway settings for the WAN interface once more. Ensure that they are correctly configured in accordance with the demands of the ISP.

3. Power Cycle Modem and Router

Resetting the modem and pfSense router may help in re-establishing the WAN connection. Turn both devices off, give them some time to cool off, and then turn them back on.

4. Check Modem Connectivity

If there is a separate modem, we must make sure it is properly connected and that all of the relevant lights are showing a solid connection. To check the modem’s operation, if at all possible, try connecting it to a different device.

5. Review System Logs

To check for any error messages related to the WAN interface, navigate to “Status” >> “System Logs” >> “General” in the pfSense web interface. Logs might offer useful details on what caused the connection drops.

6. Update Firmware

Verify that the modem and pfSense router are both using the most recent firmware releases. Connectivity problems can occasionally be caused by out-of-date firmware.

7. Check Firewall Rules

To be sure they are not preventing genuine traffic, check the firewall rules on the WAN interface. Rules that are improperly configured could cause connectivity issues.

8. Check for Resource Issues

Check that the pfSense router is not using a lot of CPU, memory, or disk space as this can make it more difficult for it to keep a steady connection.

9. Test with a Different Router

To rule out any hardware problems with the pfSense router, if at all possible, test the WAN connection using a different router or modem.
