this also a good lecture:

https://www.scivision.co/wifi-channel-ssid-power-best-practices/

He recommend 40mhz on 5ghz and use only 1/4 of 2.4ghz of all AP

http://www.emperorwifi.com/2015/08/an-explanation-of-channel-and-transmit.html

The use of 40 MHz channels at 5 GHz with 802.11n is fairly common practice. In most SMB deployments, unless the design calls for high client density (e.g. convention meeting space, large classrooms, etc.), or there is explicit issue to avoid the DFS channels (rarely a problem for indoor deployments, sometimes a concern for outdoor deployments), we can generally use 80 MHz channels with 802.11ac, and thus double the wireless throughput. This is the primary advantage of deploying 802.11ac access points vs. 802.11n access points.

This is from:
www.revolutionwifi.net/revolutionwifi/2013/03/safely-using-80-mhz-channels-with.html


You designate primary 20 MHz channels so that it results in non-overlapping 40 MHz channels. If you're in the U.S. you can't use 40 MHz channels 118 and 126 ( due to TDWR restrictions), so this results in 10 non-overlapping channels. If you're in the UK/EU you can't use 40 MHz channels 151 and 159 ( due to Band C licensing), so this also results in 10 non-overlapping channels.








802.11ac Non-Overlapping 40 MHz Channels


Remember that administrators only configure the primary 20 MHz channel, and the primary 40 MHz and 80 MHz channels are dynamically assigned by the AP. I provide a deeper explanation in my post on 802.11ac Channel Planning. In this graphic, primary channels at various channel widths are denoted with gray and dotted-gray shading.


This is fro meraki cisco:

For a deployment example where DFS is disabled and channel reuse is required, the below diagram shows 4 channels being reused in the same space. When channel reuse cannot be avoided, the best practice is to separate the access points on the same channel as much as possible.

That's right, channel allocation varies form region to region. If you deploy APs in Thailand, you should take a look at the actual allocation schemes valid for Thailand, not those for USA or the EU. Also, channels for outdoor use are irrelevant for indoor APs, since EAPs don't offer DFS/TPC as far as I know. But I don't own any US or Asian version of EAPs, so YMMV.

Yes I will try.
By the way, am I the only one to have EAP330 freezing & crashing issues? I mean even with 24h reboot I had one who crashed and I had to cut POE from the managed switch in order to reboot...
And the strangest thing is it not over charge (less than 20 user) and I was not using all the function of it. I have the latest release and I'm having this issues across 2 different sites. All using the same POE+ switch T1600G-PS28.

Is there I way to make them run smooth? I didn't experience that with any "business grade" AP even with under 60 bucks cheap hardware...
