Backwards 11ac

Backwards 11ac

[James Cloos]

I recently received my turris omnia and put it into operation yesterday.

(It is only doing wireless; I have a different box for my main router.)

All of the machines on the wlan show backwards transfer speeds; they
upload reasonable fast but downloads are in the kbit/s range.

That applies to the both the 11ac-capable machines and the 11n-on-2.4
machines.

Luci's status/overview page shows 'Bitrate: 6 Mbit/s' for the ath10k and
'Bitrate: 61.5 Mbit/s' for the ath9k.

(The two wireless cards in it are:

01:00.0 Network controller: Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) (rev 01)
02:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter
)

Googling has not helped me figure out how to get propper bandwidth.
All of the search results were about wan links, not about wlan links.

What should I look at to diagnose this?

ath10k cannot show tx rates right now in a easy way. since tx rate 
handling is done by the cards own firmware and not by the mac80211 
wireless stack

Thanks for that info, but there is still the issue that download
bandwidth is limited to around 6 Mbps whereas upload bandwidth is around
50 Mbps.

Those numbers above are actual throughput, tested via rsync/ssh.  Even
adding in the rsync, ssh, tcp and ip overheads that is still worse than
the 11n-40 on the 2.4 band.  And of course backwards.

Does anyone have any explanation for the backwards bandwidth or solution
for how to fix it?
