After going into my router settings for 2.4ghz and changing the width from 20/40ghz to be only 20ghz, I have experienced no issues. I'll continue to monitor this as the issue in general wasn't persistent, but occurred often enough to drive you crazy. I've also found here - -channels-explained-what-is-wifi-channel-width - that doing this is better anyway for 2.4ghz as there are several overlapping channels in this band.
