[B.A.T.M.A.N.] [ath10k] [batman-adv] Robustness of batman-adv or IBSS/802.11s on ath9k (AR9331 chip)

[Xuebing Wang]

Hi ath10k community,

Does anyone use ath9k driver + 802.11s (or IBSS/adhoc) on commercial 
products?

Our setup is AR9331 + ath9k driver + OpenWRT 15.05 + batman-adv 2016.1 
(PKG_RELEASE:=3)

We are very serious about robustness of running batman-adv on AR9331, 
because we have 20+ commercial sites running, each site is with about 20 
nodes.
- batman-adv + ar9331 work almost (well almost) perfectly.
- Sometimes, one node drops off the mesh, occurrence rate is very low.
- For one time, when Node drops off the mesh, "rmmod ath9k" then 
"modprobe ath9k" can get both batman-adv (and ibss/adhoc on top of 
ath9k) recover. This seemingly points to that the issue is with ath9k 
driver (ibss/adhoc mode).

As this email is mainly addressed to ath10k community (rather than 
batman-adv or openwrt), does anyone commercially use 802.11s (or 
ibss/adhoc)+ ath9k/ath10k? Does 802.11s (or ibss/adhoc) + ath9k/ath10k 
work perfectly?

Thanks.
Xuebing Wang

I'm running batman-adv on LEDE-project (r1497) on a TP-Link TP-WDR3600
with ibss/adhoc + ap on the 2.4GHz radio.  This is ath9k, not ath10k.
Seems to work fine, no problems.

Hi Russel,

Thanks. By "work fine", do you mean that you have 20+ nodes running for 
at least a month without any issues?
