As another person suggested 5 Ghz is much less crowded. You said you had tried an N router. Are you certain that the N router was using 5 Ghz exclusively? There are a fair number of N routers that use both 2.4 Ghz and 5 Ghz for N. There are even a few that are 2.4 Ghz exclusively. The tipoff (outside of reading the specs) on the exclusively 2.4 Ghz models is that they don't have 802.11a backward compatibility since they have no 5 Ghz radio. I would make sure that the N router you are using is only using 5 Ghz. Also have you tries both 20-MHz and 40-MHz? All 40-MHz really is is two adjacent channels bonded together.In theory the router is supposed to shift traffic to the less interfered band if one band is getting heavy interference.
The reason that 5 Ghz is superior to 2.4 Ghz outside of the limited use is that there are more channels available. With 2.4 Ghz (802.11 b and g) you have 11 channels but only 3 are non-overlapping. Throw on top of that that at least one or two of your neighbors have probably decided to use one of the in between channels because it is "clear" and you have a few neighbors who are interfering with two of the non-overlapping channels. Each channel overlaps 2 channels above and 2 channels below so for example channel 1 uses channel 1-3, Channel 4 overlaps with 2-6, channel 6 overlaps 4-8 etc. As you can see a user using channel 4 overlaps with channel 1 and channel 6 making them a very annoying neighbor. Channels 1,6 and 11 are the only non-overlapping channels. With 5 Ghz wireless (a and sometimes n) you have 22 non-overlapping channels to choose from. If you are using 40-MHz all 5 Ghz you will use 2 adjacent channels but you are still talking about a much larger number of available channels. Unless you are in an extremely densely populated area you should be able to find some available 5 Ghz space that is either open or has limited interference. Another option you might look at is setting our network card to 802.11b only. 802.11b can deal with a lot more noise than 802.11g.
