On startup of the IBSS network, there is a chance the Pi goes into a tizzy https://github.com/openwrt/mt76/issues/543 - when it's the first (and only) node. > I was able to dupe it consistently in my home - fairly static network - but not anymore in a lab environment.

It doesn't seem to me like this is batman-adv or batmand related. So I would most likely better to ask on linux-wireless@vger.kernel.org too And is IBSS mode really required or would meshpoint with mesh_fwding set 0 also work? iw phy0 interface add mesh0 type mp ip link set up dev mesh0 iw dev mesh0 mesh join 11s-bat freq 2412 HT20 mcast-rate 18 beacon-interval 1000 iw dev mesh0 set mesh_param mesh_fwding 0 # please make sure that it is actually 0 with: iw dev mesh0 get mesh_param mesh_fwding ip link set master bat0 dev mesh0 > I have ascertained that NONE of the USB Realtek dongles work, as the kernel driver is missing IBSS support at this time... > > I'm against an urgent deadline, and trying to understand what I can do to make this work Kind regards, Sven --nextPart3186444.dtHR1CuC4E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
