Problems Configuring VHT160 and VHT80+80 for QCA9984

Problems Configuring VHT160 and VHT80+80 for QCA9984

[Robert Jones]

Hello,

I'm working with a WLE1216V5-20 ath10k wave 2 card using QCA9984
chipset and having problems configuring an AP for VHT160 or 80+80
mode. The hostapd v2.6 tool in both cases tells me that the "Driver
does not support configured VHT capability".

I'm using the custom board and firmware .bin files found at
http://www.candelatech.com/ath10k-10.4.php. I see on the same page
that they recommend using one of Ben Greear's kernels but I would
prefer to stick with a mainline 4.14 if possible.

Is this capability truly missing from the ath10k driver or am I
misconfiguring something in my hostapd.conf?

If the former, can anyone point me to a patch set that I can apply to
the ath10k driver to support either of these two modes?

Regards,
Robert Jones

Early on there was bugs in stock firmware for how it did VHT160
vs how the driver thought it did.  I ended up fixing the CT firmware
to match closer to how the driver wanted it done at the time, but
I think that the driver has since changed.

I have not had time (nor much interest) to try to make my firmware work again with stock
driver for VHT160.

Either way, VHT160 is almost completely worthless because it can only
do 2x2 at VHT160, which is no faster than VHT80 at 4x4 but uses twice
as much bandwidth.

Thanks,
Ben

remember my patch to get it to work with stock firmware :-)

Right, I definitely agree. I suppose I just wanted to test my
configuration in case one of our customers asked for an example.
This is a strong argument regarding this card though.

[Sebastian Gottschall]

i disagree with ben since his argument doesnt cover outdoor longrange 
links. 4x4 is worthless for long range links since dished are only
available with dual polarization feeds with allows only 2x2
the world isnt just made of plastic home routers
