Confused about 802.11s instructions

I have two TL-WDR3600 v1 and one TP-Link TL-WDR4300 v1 on my hose, on each floor.
I want to activate roaming in 2.4 and 5 GHz, but I have problems with configurations and instructions.

  1. The official wifi fir 802.11s is made for OpenWrt with batman-adv 2019.1 and later.

  2. I use OpenWrt 18.06.4 r7808-ef686b7292 / LuCI openwrt-18.06 branch (git-19.218.48077-4468345)
    and this installs an older version - 4.9.184+2018.1-8 (not 2019.1+)

  3. I've found some instructions about my version of batman-adv (2018.1-8) here, but I do no know how to verify if it's working.

So what should I do?

The simplest way should be to upgrade to 2019.1+ version of batman-adv, but I do not know-how to doit.

@Macrisu, welcome to the community!

I think you missed something on that official page:



Hope this helps.

(BTW, as of this posting, 2019.3-0 is available if you install a snapshot version of OpenWrt.)

I'll try the old instructions, I know about them, but it does not say that the instructions are for 2018 version or older :slight_smile:

Punctual questions:
So, for the 3 AP, I use the same IP -, or I use different ip's like:,,

config interface 'vlan1111'
        option type 'bridge'
        option stp '1'
        option ifname 'eth1.1111 bat0.1111'
        option proto 'static'
        option ipaddr ''
        option netmask ''
        option delegate '0'
  1. If I want roaming for 2.4 and 5 Ghz, I will copy paste all the codes and only modify the device and mesh id?

802.11s, or mesh, in general, doesn’t have anything to do with consumer devices roaming from AP to AP. The phones, laptops, ... , never connect to a mesh as they don’t support the protocols. The mesh only connects the APs wirelessly. Wired, if possible, is preferred.

For roaming, the same SSID and subnet is usually sufficient.


Ups, so MESH it does not help me for roaming.
I have the classic receipe: same SSID, and subnet, differerent channels, but sometimes I have problems between floors.

I see option 802.11r Fast Transition, this whould help me?

Thank you!
