Hi,
It appears that the official drivers for those chipsets do not support mac80211 and I can't make virtual interfaces with them. So I had to take TP WR740N router, put OpenWrt + batman-adv on it and make it the entry point to the mesh network. That didn't go without problems, but at the end it worked.
great!
BTW - the instructions on the web site about installing batman-adv on OpenWrt are outdated and didn't work for me. I have installed batman just doing - /opkg update && opkg install kmod-batman-adv/.
What exactly are you referring to ? What page / which instruction ?
Regards, Marek
