It is a great router and it does almost everything I need. QOS has glaring omission and that is to be able to QOS IP ranges (ie 18.104.22.168 - 22.214.171.124). I contacted tech support and it appears this functionality has been dropped since the original firmware. It's important to me becuase I have backup software I want to throttle when people use the net and it operates from a range like that but rotates ports.
Was debating Tomato USB (since it has worked for me great on my old asus router) but I am intrigued by the Merlin firmware. Thanks for sharing.
