Hi,
NAS ist cable-connected to the archer c7. Rest will i do later - im @work 
regards
option htmode 'HT20'
This. Try to increase it to HT40 or higher (on 2.4Ghz HT40/40Mhz is the max) and hope/check that the other device(s) can handle HT40/40Mhz too.
The media streams at 1080p can get to a bit rate that is higher than what HT20 can handle, I don't recall the exact reason, it's not about raw bandwith, but about quantity of data per packet or something like that. Bitrate of wifi being lower than the stream's bitrate maybe.
I know for sure that it was an issue for wifi streaming for some Android media centers (Minix neo x7) that had only a HT20 wifi onboard so 1080p streaming was pretty much a hit-and-miss depending on file bitrate, while if connected on ethernet the same file was played fine.
Hmjmm, thats my 2.4Ghz WiFi. Into 5Ghz is no "rc_stats"

Ok, this says that you are connecting ont he 2.4GHz band, how congested is that
in your area?

you have 2.4G set at HT40, or two channels, and on channel 11. hopfully this
means that it's using channels 6 and 11, but this means that any station in the
area on channel 2+ is going to interfere with you.
you show two different SSIDs, one for each band, make sure you connect to the
5GHz one.
pull multiple copies of this file while you are attempting to watch the video
stream.

you are picking HT80 on channel 48, I'm not sure if hte HT mode settings are
telling this to use channels 36-48 or 48-60 (or if the driver auto-aligns to the
'proper' slot of 36-48 no matter which of these channels you enter)
I would try on channel 36
I'd also check the output of iw info to see exactly what the radio ends up
getting set at.
Hi,

by the way, this says that the radio is only running at HT20, not HT40

If you are connected at 5G, and have not recently connected at 2.4G, then you
should not have any station stats for your mac address on the 2.4G radio, only
on the 5G radio.
Something is not working as you think it is.
David Lang
Possible - but if i shutdown 2.4Ghz and my stuff (exept one old smartphone) are working - the 5Ghz is the only one who is online. And there is no rc_stats - not sure why.
I try a lot of thing last 30 minutes. Speedtest, try videos from nas via wlan. No rc_stats within 5Ghz and NO other channel as you see here with HT40 setup. Also a reset (remove "wireless" and reboot did not bring some news.
Maybe a bug? I have no idea and i have no reason to lie.
