I have two wireless access points. I've been reading much advice on choosing channels and everyone says use 1, 6, or 11 to avoid interference, since frequency bands overlap. That much I understand. My question is, if everyone near me uses these three channels, is it better for me to use them too, or should I use 3 and 9 instead?
In other words, will I get more interference from other traffic on the same channel or on a neighboring channel? I can see valid arguments for both, but it seems to come down to subtleties on how the protocol handles conflicts. A neighboring channel may garble my packet but the same channel might land a packet on top of my own.
No. 3 will usually overlap with both 1 and 6, and 9 will overlap with both 6 and 11, so they are actually the worst channels to use. _________________ SIG:

I live in a big block of flats and wifi situation is pretty difficult here. I have tested all channels and 8 works significantly better that 1,6 or 11. There are at least three nearby networks on each of those channels. I get double speed on channel 8. _________________ Netgear R7000 running BS DD-WRT build 26446 (home)
Wow -- I had always been under the impression to scan your area with inSSIDer... then choose the most "open/unused" channel. In my neighborhood everyone seems to be on 1, 2, 3, 6 and 11. So I have had myself on 8. Interesting article, but it really goes against everything I had believed. I may have a hard time changing.
...and sure enough, there's plenty of conflicting information even among the reliable sources. Some say to share channels, some say to find an unused (or least used) channel. Overall the tone of the latest articles I read seem to imply the "everyone on 1, 6, 11" advice is outdated and may no longer be necessary with modern routers and devices.
