Hi all. I think this is a generic issue, but I wasn't sure of the best forum to post it.

I struggled at first to get a new netgear XR500 stable (hence posting here). I was having DNS resolution weirdness. I eventually tracked it down to bad parameters for the DHCP address range.

I had put in 192.168.1.110 as the start and 190 as the range (copied from my old router). I had changed the start address but forgotten to update the range to be within the class C limit. I figured it out by telnetting into the router and enabling logs. I knew enough to be able to debug the issue and resolve it.

My feature request is to validate the start and range parameters before writing them. That might save someone else frustration and confusion down the road.

Thanks!
