Hi!
I’m the one who had the suspicion that there might be a limit in the number of batman-clients per node.
Just to make things clearer:
* The node was using the 2,4 and 5GHz bands (not just one band). There was also no interference from other wifi networks (basement location).
* Network access and throughput was acceptable for the 72 clients (with high pings at times) that actually got any data through.
* The problem might very well be unrelated to batman. It’s just that clients got a WLAN connection (so probably no hostapd issue) but a lot of those time-out without even assigned an IP.

So this might as well all be a driver issue e.g. <https://dev.openwrt.org/ticket/11862> as mentioned!

P.S. I did not want to accuse anyone or spread false facts. Now we got the answer that there is no known limit in batman-adv, we need to look elsewhere for the limitation before deploying our mesh network to potentially 1000+ clients at a campus.
Here, FWIW, the complete logread during the conference. I was just a participant and my task was not to diagnose the network. So this is all I have.

would you mind sharing some details regarding the experiments you performed ?
The reason for this question is that there is no 72 client limit we know of
(unless fragmentation was disabled).
Cheers,
Marek

Hello world,
During an experiment it was found, that BATADV_FRAG_MAX_FRAGMENTS=16
allows ~72 clients to be connected to one single access point.
This parameter is defined in batman-adv/main.h [1]
What negative side-effects should I expect when doubling that value at
compile-time?
Christof
