I have a Netgear WNDR3700 router running DD-WRT v3.0-r28139.

Whenever my MacBook Pro or Chromebook laptops enter sleep mode and I'm watching a streaming TV program on Roku then within a few seconds of either laptop entering sleep mode the Roku starts buffering. If this continues for too long my Android phone starts dropping its WiFi connection.

If I open the lid of the laptop that is sleeping to wake it from sleep mode then the Roku buffering stops and the Android phone stays connected.

Are there settings I need to change on DD-WRT to stop sleep mode on either laptop from affecting the rest of the network?

I managed to fix the problem.

The buffering on streaming TV programs was fixed by lowering the Sensitivity Range(ACK Timing) to it's minimum of 450.

The additional issue with TV streaming was the TV show would end but not cue the next show or automatically start the next show. I would have to manually fast forward the show to the end. This was fixed by changing the Wireless Network Mode from NG-Mixed to Mixed.

So in fact neither the MacBook Pro or Chromebook laptops had anything to do with it? These were red herrings?

I know when I first read the post, I was clueless as to how these could be related.

They did in as much as both of them were invoking the sleep process and that was causing the router problems which in turn disrupted the timely flow of TV streaming.

I've seen on other non dd-wrt forums that people have had the same problems with sleeping devices.

I too don't understand the ACK timing/sleeping connection but am pleased it's fixed.
