I am using TomatoUSB v1.28.8754 on an Asus WL-520GU router. My WAN connection is DSL using PPoE with a dynamic IP. I've been running the current setup on this router for 2 years or more without problems. Recently, I started having problems with the WAN disconnecting several times during the day, sometimes every few minutes. When I look at the status of the router, it shows that it's still connected, but I'm unable to ping anything on the internet. If I press the disconnect button, the status changes to "Disconnected", but I am unable to reconnect to the WAN unless I reboot the router. I have the log levels set to 8, but nothing shows up in the logs when the disconnects occur. I would like some suggestions for how to troubleshoot this problem. It's possible that the problem is with the router hardware, but I have no way to know for sure. Can anybody suggest something I can try to diagnose this?
