I have Cisco RVS4000 router. I notice that internet connection dropps frequently continously throughout the day. It has became worse after upgrading to the latest firmware (18.104.22.168) /IPS signature (1.4.1).It looks like it is dropping the connection every 10-20 minutes. I've reset MTU to manual and set at 1492, 1472, 1452, 1497, etc with no avail. It continously drops connection.
Also, status page doesn't display connection data correctly either. It would display it's connected eventhough connection was lost.
What is going on with this router ? Any help would be appreciated. Thanks.
