Living in a high density area of my small city, several years ago I noticed an increasing number of WI-FI access points as everybody in the neighborhood acquired a basic bare bones wireless router. I also experienced an interference problem with my neighbor's wireless printer. I decided to convert to a dual band router and leave 2.4Ghz behind. Using a neat piece of software called ainSSIDer to monitor the bands, I was delighted to find I was the only person on the 5Ghz band. The only draw back is the shorter range of the upper band. All the problems solved.
