Depending on the hardware, 40Mhz, 80, or even 160Mhz widths are available. I've owned the 1900ac which supported as wide as 80Mhz as well as the 1900acs, and 3200acm which supports 160Mhz widths. Currently those widths with the latest driver are working correctly.
According to what I see in the Wifi config, there is only 1 SSID, and the configuration appears to be messed up. I see 'radio1', but 'default_radio1' for the encryption/key etc..
Please completely remove all of your SSID's, and check to make sure the wireless config reflects nothing configured. Then re-create 1 SSID, and check to make sure it is working properly before moving on to the next one.
See if that gets you pointed in the right direction.
A bit off topic, but now that OpenWrt forums are gone, hopefully Davidc502 will start a new thread here at LEDE for discussion of his builds. Hoping he also adds WRT32X now that official support has been added to master.
The next build will include support for the 32X. I've already been outfitting the website for the new image. The GUI is pretty much done, but the back end scripts still need to be written which really isn't much.
OK, I removed /etc/config/wireless file then flashed your last FW (2018-05-11 00:27)
Then setup wireless "from scratch".
I recorded a video for you. http://take.ms/qy7lH

Sorry for hijacking the thread but I wonder if there is a general way to improve wifi performance with the WRT3200acm... ?
Disabling "Allow legacy 802.11b rates" at radio0+1 should improve performance (option legacy_rates '0') ?
What about "option noscan '1'", should this be in my wifi config as well ?
I'm using the EU version of the WRT3200acm and i'm using the latest build of davidc502...
“option noscan ‘1’” needed to prevent your router "fall" to 20Mhz band if your neighbours have wi-fi too. But I can't recommend you do it always. You should analize your situation. In case you need the fastest link, you should use wide band. In this case you could sacrifice a coverage because your neighbour's collisions may interfere. If you need a maximum distance you should use 20Mhz on free channel, maybe legacy bands switch on too. The common rule is "the small frequencies is slower but long-ranged"
My aim is only cover 70 sq.m. flat in high-rise bldg and make a "beam" to the bench in my yard if I would a work in summer with my laptop. So, I just put my router on the window sill and maximize signal power
OK, and what about 3rd SSID? E.g. on the LEDE 17.04 FW I have one 5Ghz AC SSID and two 2.4 SSIDs
In your build only 2 SSIDs are possible? New driver 'exclude' one radio-module support?
Full 17.04 /etc/config/wireless is
You are right, but very strange... My Android-TV uses 40 MHz band, my OnePlus 5 smartphone never. My wife's Xiaomi smartphone use "wide" band, my daughter's IPAD not. Both of my laptops works fine in 2.4 40Mhz and 5GHz AC bands. My noname tablet doesn't reject WPA2 auth (when router worked under LEDE 17.01 it was a trouble). So, I think wireless performance and bands depends of wireless clients. It sounds strange because 802.11n is very "old" standard but facts is facts.
Of course ISP speed may be a reason (I have 100 mbit/s WAN only) but I tried to send 4K movie via LAN - result the same.
