Hi,

The section from the System Log you posted only tells us that the indicator light for the "LAN" ports is switching ON and OFF.

This should only happen if an Ethernet cable that is connected to one of the LAN ports (LAN1 to LAN 4) is repeatedly loosing its connection.

Can you please re-check that these "Led Controller INFO [746] Start to run LAN_ON / OFF" only happen when you are connected via the VPN?

It would be very weird if those messages only appeared when you are connected to the VPN.

In case you see these messages all the time, no matter if connected to the VPN or not, then I recommend you replace the Ethernet cable you are using.

If there is currently more than one Ethernet cable connected to the four LAN ports, then you will have to find out which one is triggering the LAN_ON / LAN_OFF messages.

these messages do not appear just when on the VPN - they seem to appear constantly.

Regardless, the VPN issue persists.

Ok. Do you know if your company's VPN software was updated recently, around the time when the problems started?

  @woozle No they haven't. I had a few conversations with them today about it. Additionally, my ability to access the VPN without disconnects still works in other networks, such as at a friend's home.

  @tdhuff0803 Are you connecting to VPN using Archer AX1800  VPN client? (that is, if it has one)

  @GlaisneWalsh I don't use any VPN feature on the router itself. I connect to the company's VPN via a downloaded application (similar to how one would connect to like a NordVPN).
