I have a Linksys RV042 that I purchased in the summer of 2004. It has been running 24x7 till about a week ago, without a problem. It has been connected to the Internet via Cable Modem and it has performed well over all and other than some glitches and issues with the VPN, I can't really complain about it till now. The firmware has been updated regularly and it is running the latest firmware posted on the Linksys web site as of today. Now it seems that after the RV042 has been on for about 5 to 8 hours of use, it just locks up and refuses to process any info in or out of the device. Resetting the device while it is still warm does not seem to help either. After leaving it sit for a couple of hours, I can plug it back in and put it back in service for another 5 to 8 hours when it will just lock up again and refuse to accept any commands. My thoughts are at this point that the unit has an over heating problem. It is also possible that the unit could have an AC adapter that is going bad, but I feel that is a bit more unlikely. Has anyone seem this? Does anyone have any suggestions on how to solve it? Anyone have any suggestions on getting it replaced?? Linksys says that it is out of warranty and the only solution that they have is to buy another one. Is anyone here doing repairs on the RV series?
