I've been using RVS4000 for many small business projects as it has a good feature set for a basic networking solutions. Unfortunately I had to replace at least 4 units (and counting) due to unpredictable "stopped working" situations. For router/VPN/DDNS solution they were replaced with RV042 but with the loss of gigabit switching. Unfortunately, there is nothing else in the product line with gigabit+router. I have experimented (at my office) with two of the RVS4000 and have suffered the consequences. This device has a MTBF of 3-4 hours. I've tried resetting, using limited features and FW1.1.14 but nothing stops the units (I've tested 2 so far) from hanging. When it does hang then the only recourse is to power off/on and it always comes back to life. Has anyone else has similar experience and/or a solution?
