Theveterans is right. The 5 Ghz band is great to reduce radio interference. And a good router makes a big difference. I get good range on the 5 Ghz band and my 2.4 Ghz band performs better after I bought a Netgear N900 Dual Band Gigabit Router (WNDR4500). I replaced another brand of router, whose name I shall not mention. The difference was like night and day. I saw the Amazon reviews before I bought the router and other people were also having good luck with this router. It's not a fix for every wireless issue, but a good router or access point does make a big difference.
