I just wanted to share my experience with a pool of RV042 routers that we installed to provide VPN services to satellite offices. We purchased five RV042 routers and one RV082 over a period of several months, nearly two years ago. To date, we have had four of the RV042 boxes die. The symptoms on all four were very similar--the DIAG LED comes on and the router stops communicating over one or more of the WAN/LAN interfaces. Sometimes a reset would bring the routers back to life for a few hours. A couple of weeks ago we ripped apart the four failed units to see if we could identify any failed components on the board. After probing around with an oscilloscope, it became apparent that the 12V to 3.3V switching converter on the RV042 mainboard was not operating correctly. We measured almost 500mV of ripple on the 3.3V output--way too much for proper operation of some components. It appears that the low ESR capacitors on the converter output had degraded over time. After replacing the capacitors with new ones, the converter output was cleaned up enough that the ripple on the 3.3V output was less than 30mV. We have put the repaired routers back into operation and over the course of the last week, we have not seen the routers stop working even once. I just ordered a new RV042, which should be here today. I am going to take it apart to see if Linksys has changed the power supply design, or components. It certainly looks like there is a serious flaw with the units that were sold two years ago--I hope they have fixed this issue in newer units.
