Is it possible to make DHCP respond more frequently/faster?

When I turn on the XBOX360 and the Smart TV and they start booting, they both take ~5 seconds to get on the network (determined by the icon changing on the smart TV, and the XBOX logging into XBL. This almost always happens at the same instant for both devices, making me think they are both waiting for a router response. Is there a way to make the router respond to the DHCP requests faster?

Both the main router and the switch the XBOX and TV are connected to are Asus RT-AC66U.

I doubt whether there is a speed issue with DHCP as in my experience it responds in less than a second. You can check it by looking at the entries in the syslog. Here's an example for my PS4.

It could be some other initalization stuff, like a slow polling for the initial link detection rather than DHCP. Is any of that configurable? It seems odd that devices started up a second or two apart tend to get online at the exact same moment.

To be honest I suspect it's just coincidence. I can't think of anything configurable on the router that would be related. All the network stuff is event driven not polled.

The roku is doing the same thing. Interestingly, it is quicker in the basement, where it talks directly to the main router, then in then den or bedroom where it goes through a dumb switch and then another router acting as a local switch/access point. So I guess there is some propagation delay / polling interval involved in devices finding the main router through those couple hops.

Even then it should never take that long to get address, I think it is config issue on your side.
