You can't expect people to use channel 13. Much kit only works with US spec, such as Broadcom cards, and other kit won't auto tune to 13 (lots of routers come default to auto) or some such other issue. Add to that the huge amount of advice on the net to use 1, 6 & 11 (US-centric of course, but it's all over the place) and you can't expect others to use channel 13.

If you can get away with using it yourself of course, it can be a relatively unoccupied channel.

Best to assume your neighbours will follow the US model when planning your setup. Their auto probably will if they don't change it and default fixed channels are always 1, 6 or 11.

Even if you can fit a wide channel in, you should only do so when you want to transfer a big file then switch back. Otherwise no-one else will be able to use the space when they need it. Only use what you have to on the 2.4Ghz band, not what you can. Just because it is free at the moment doesn't mean you can stick your towl on it.
