I always set network mode (AC/N-Mixed), save; channel width, save; extension channel(s), save; then channel. That is how the UI seems to want to play nice, as I have previously stated, I think, quoting Per Yngve Berg (?)...
Thank you. I did miss the first link and need to test the recommended settings, although it seems a bit strange to work with a lower fragmentation threshold and with max transmit powers. For sure it extend the range, but it might be counterproductive if you are working in confined spaces such as corridors.
That being said, the issue with the channel might be specifically linked to the RT5300 but it is definitely not a GUI issue. The channels are unavailable regardless of the country and I did try all possible combinations of GUI setting step-by-step.
CH13 and 14 appress w/o problem when you set USA. But there is no sign of CH100-144. Anywhere.
It might be interesting to try and set this channel via command line. I tried but not sure which is the correct command to be used.
Anyway, I confirm that using N/AC-mixed instead of AC-only did improve of ~10% transmission. Although it should have been the other way around. Perhaps just a better implementation of the wl drivers for this freq.mode?

I just noticed something. Are you using the regular or experimental driver firmware image? If you aren't using the experimental driver firmware image, that might be part of your problem...
I did try both experimental firmware r45820 and r45767. Neither of them is stable in terms of wifi settings.
Yes I do see all the channels (regardless of the application of the nvram workaround), but after selecting the wanted channel (any channel really) and applying such settings, but the time the page comes back up, some settings cut as the channel are missing and channel width also is changed. An empty list may also appear in the GUI for the channel selection field.
My focus is on ch100 because:
a/ there are so little 80mhz frequencies without radar in my house/area, and ch100 seems to work best of them all - I've also tested the area with a MikroTik router and that channels works best.
b/ the same Asus router I'm using with dd-wrt in the exact same location and position (and cable, etc). was yielding better results on ch100 on stock firmware
Since I switched to dd-wrt to implement vian and a bit of more refined networking (I'm in love with the firmware overall btw), I would like to understand the reason behind not being able to select a channel that is a standard and available on stock firmware - I find this a quite base functionality compared to all the advance features that dd-wrt offers.
Thanks.
PS: All my tests have been conducted in comparable scenarios taking into considerations walls/router positioning and environmental factors (e.g. number of devices connect the AP simultaneously, etc).
