C3700 IP Address Reservation Table Full?

I can't say for certain what the default lease duration on that particular router is, Netgear often uses a 24 hour duration, and they rarely make it user definable on their residential product - personally I think a 7 day duration is excessive (that, by the way, is what Microsoft uses to default to with their DHCP servers) - on a small, "non-dynamic", network, you can get away with it, but for larger networks it's asking for trouble - I've seen networks where the admin has chosen a lease as short as 25 minutes. The thing about DHCP, DHCP reservations & static addressing is this - there is a time & place to use one over the other - most of us don't need to have more than one device at a fixed address (the router) and in that case DHCP will work fine, once the network starts to grow in complexity and specific devices need to be at specific addresses that's when you have to change things. I don't use Netgear's residential equipment - not even in my home network - everything I've purchased comes from their business line - it costs more, but it gives me the flexibility to set things how I want it. It is a sad fact but residential networks have grown in complexity to a point where the average home owner needs to make a decision to either invest the time to learn about the technology or to pay someone who has made that investment to install and maintain the network.
