Hi all,
I'm using 802.11s to do mesh networking with ath10k on an OpenWRT
router. My throughput across the 802.11s connections is very low,
around 22 Mbits/s maximum. When I search my device with iw[1], I am
informed that the driver believes it is operating in 20MHz channels.
When I run it in AP mode, I get much faster speeds and iw claims the
interface is acting with an 80 MHz channel.
Is there any way to increase channel widths in 802.11s? If this is an
OpenWRT question and not ath10k I'll head over to the forums, but this
seemed more a driver issue as my wireless config requests wide
channels. Any chance there's a specific version of ath10k I should
push to?
Any information would be much appreciated, and I'll be happy to answer
any questions.
Thanks,
Zach

I can use the 5GHz band as an AP and get much higher speeds (in the 100's or more) so I know the 22 Mbits/s is slower than the maximum, though I certainly could be wrong on the channel widths point (it could be the modulation scheme, maybe?).

I mostly am interested in knowing the modulation just to keep track of my theoretical maximum throughput for monitoring. The Rx rate was changing correctly now, which is great. I know the Tx rate is totally unreported, but the Rx is all I need. Thanks again for all the assistance, I think I have everything I need.
