Bluetooth and airport signal interference

My magic mouse and keyboard are becoming unresponsive every now and then.

For a couple of weeks I was fixing this with PRAM and SMC reset.

I finally I found out that the problem was bluetooth and airport signal interference.

When magic mouse and apple bluetooth keyboard become unresponsive, shutting the airport off solves the problem instantly.

I use a time capsule, would you suggest alternate setting to prevent this problem from occurring ?

Thanks
