I used to use the older Linksys VPN units (i believe BEFVP41's) and those worked great for the longest time. I needed some more speed and realized that the BEFVP41 couldn't do more than about 3mb/s over it's WAN port. So I started looking for a good replacement and purchased two RVS4000. One of them keeps requiring a reboot every 2-3 days. Basically it stops passing traffic to the internet altogether and when I try to go to the admin page it prompts for the login, but then it just displays a blank grey page. The unit is only about six weeks old and it's running the latest firmware. Reboot it by pulling the power cord and putting it back in causes it to come back, but it sucks having to drive to the office to do that just so I can work from home at night or on the weekend. Does anyone have any suggestions?
