I've had 3 RVS4000 routers and taken back 2. With every Firmware available I experience a sudden drop in internet connection. Once the internet drops there is no way to reactivate. I use a static ip connected to a T1 line. I have 2 other routers (backups) configured to use my static T1 line, and both work fine. I have troubleshoot every imaginable link in the chain. Has anyone else experienced this problem and if so... Is there a work around? I really like the router when it is working. Currently I am using the new 1.1.09 Firmware. After the Factory Default went *poof* I restored and upgraded.
