If you are in Europe set channel 13 + lower. In the US this channel is not legal. The result is 11+13, but you have to check what your neighbours are using first. In a crowded environment, set 20Mhz width.

Ye I am from europe and I had 13+lower+40Hz which ended up with 13+9 I think.
The place is really crowded...I now chose 13+20Hz (then the lower/upper option disappears) and it seems to work better.
The channels that my neighbors are using are switching all the time. But it seems like no one is using 13. 1,6,7,11 are the most used ones.
14 would be best (according to wifi analyzer) but I am not sure if all devices support channel 14?
Also channel width 20Hz makes the transfer speeds slower than they would be with 40Hz?

Think of it as the 20Mhz as a slow vehicle that goes from A to B without stopping. You are passed by a fast car (40Mhz), but it have to stop at the red light in the next crossing and you catch up before the lights get green.
But 1,6,11 are the most crowded ones in my network where as 13 isnt used by anyone.
And I cant fix on e.g. channel 1 (which me the least crowded from the three) because the other routers seem to use "automatic" and always switch around.
In that case DD-WRT needs an option to "auto between 1,6,11".
I read the article but I am still not sure why 1,6,11 would still be better than 13 when each of the three channels is used by 4 other routers but 13 not beeing used by anyone?
13 overlap adjacent with 11. To use 13, 11 have to be free.
Alright I think I got it.
Well I am now on channel 1 which sometimes is the least crowded one out of 1,6,11. but the other wifis just jump around channels like crazy and sonetimes 1 ends up being the worst.
I think dd-wrt could really profit from a "auto 1,6 or 11" mode.
Don't you want to go around and knock on all your neighbors doors, educate them on wireless security, and channel congestion, then coordinate and say you use channel 1, you use channel 6, you use 11, you use 1, you 6, you 11. Get the pattern here people??
You at the end of the block, start with 1, etc. etc..
But then again this all goes out the window with multi tenant housing when you get into multiple floors etc.. Then you do as suggested and be one of the few networks, or maybe the only network using the 5ghz band amongst your shared airspace. _________________ R7000 Nighthawk - DD-WRT v3.0-r50308

Nah... I currently see 12x 2,4ghz wifis. There are 3 apartements in each floor. And it seems like some ppl are even running two different 2.4ghz wifis at the same tine lol.
The faster approach would be to crack their wifi pw, router pw and then change it myself -.-
Every 10 seconds either 1 or 6 or 11 becomes the prefered channel. On the screenshot above it might look like channel 6 is best but that will change in just a few secondy/minutes.
When taking the screenshot I set 4 steps away from my R7000 (my wifi is named "Simy").
