I had a similar problem in my household. The tool "InSSIDer" showed me alle neighbor networks. Over 20 on 2.4 Ghz. Only solution for me was to switch on 5Ghz Channels. Unfortunately in most cases this means new router + network card. But i´m the only 5Ghz Wifi User in Range. But should be the last opinion, cause of the costs.

Dispicable Me 2 was nice
