DIR-615 releasing IP too often

IP leasing basically says an IP address for ABC PC will be available for that PC when it connects during a time frame. Because your's is set once per month another PC might be trying to gain access to the router for connectivity but be using a static (preset) IP address instead of a Dynamic (randomized) IP address.

Try setting this for 24 hours and run it for about a few days and report back any problems.

Been a couple days since I tried ur suggestion. Still the dc'ing continues. =\

Edit: I forgot to mention, I set up the ASUS RT-N16 to run on Oleg's firmware 1639 ('cause the recent updated version had wireless issues apparently).
