Archer AX20 keep disconnecting WAN
Hi,
I have a 3 months old Archer AX20 that keeps disconnecting the WAN link very often, sometimes even multiple times a day. When this is happening, the WAN LED goed amber, and there is no internet for any device, regardless of the connection - wired or wireless. The only fix is to restart the router or release/renew the internet connection. As you can see in the log below, there are a lot of WAN on and off entries.
I called my ISP and there is nothing abnormal on their side. They said that the router is dropping the connection.
Here is an example of the log from today when the issue happened:
