This is a very good time for me to point out that there are only three (3) channels that you should ever set your wifi device to: one (1), six (6), and (11). The reason why is because the "channels" overlap with each other. Channels two through five will interfere with six and one. Channels seven through ten will interfere with six and eleven. Setting yourself up on a channel that's not 1, 6, or 11 will cause interference to others and they will be interfering with you in return.

The chart found on this page will illustrate the problem with the "channels" as selected.

So yes, Wi-Fi devices having "11" channels is nothing but a lie from the marketeers.

What happens if you set it on Euro channels? Do you get black helicopters?
More like black crown vics and men in cheap suits.
That's the 2.4GHz band, and your Wi-Fi is either covered under "ISM" or as a "Part 15" device. Either way, you're expected not to bork anyone else's signal. You'll find the FCC's frequency allocations here:

(you probably want to scroll down to page 36 (as indicated))
Note that there are amateur radio operators that you're sharing the band with, and they will report you if you do anything naughty, to say nothing of the other users of the spectrum.
