I purchased this router as an upgrade to a Linksys RV042 because I needed the QoS feature for VoIP.Unfortunately it seems that there are significant problems with the firmware which cause the router to lockup for unknown reasons in a variety of configurations.There is a long thread on this issue in the public Netgear support forums, and while Netgear is aware of the issue there seems to be no ETA for a fix. As of the time of this writing, the latest firmware is 1.1.21 (beta) and it does not fix this issue.I am hoping that Netgear can clear this problem up. When the router was up and running it seemed to work just fine. If you don't need QoS, I'd recommend the Linksys RV042. If you do need QoS, hold off on this one until the firmware issues have been fixed. Make sure to check out the Netgear support forums first. If you can't wait, have a look at the Xincom Dual-Wan routers.. the DPG503 is the most similar in features.
