Router Settings?

I just upgraded my router from a Netgear to Asus, and began having problems connecting to my DS4K. The app is now having difficulty finding the DS4K and Sidekicks, and I have to hit Search Again several times before it will find the DS and Sidekicks. Once it does find them, there is about a minute delay before it will actually turn on. Everything worked perfectly before switching routers, so I'm sure it has to just be a setting somewhere on the router. Has anybody run into this and have an idea how to fix it?
