I recommend changing the wireless channel in the router settings. You may need to change it a couple times to find one that is not congested.

There are free Android or iOS apps you can use to see all the Wifi networks your home is picking up around you, and see which channels they are all on so you know which channels to avoid selecting. Works like a charm for me, the one I use on my Android tablet is called Wifi Analyzer.
