Help creating a guest SSID on a mesh network

Installing and Using OpenWrt
1

Hi I finally got my mesh network up and running and it's great (though a little slow). I'm using the 2.4ghz for the backhaul. I want to set up a guest SSID on the 2.4ghz (for my home devices). Should I use these instructions to set up a guest network or will it slow everything down? https://openwrt.org/docs/guide-user/network/wifi/guestwifi/configuration_webinterface

And if I do it, should I create the guest network on the main node connected to the ISP router? Or can I create one on the mesh nodes? Do I need to create it on all nodes?

The mesh backhaul does not support vlans so the traditional method used in a wired network does not work.

You have two options to implement this:

  1. Install mesh11sd version 5.0.1 (release imminent, hopefully this week - beta available if you want). It sets up a guest network over all meshnodes by default without using vlans, but also supports vlans if so desired)
  2. Start from scratch and use Batman-adv, but then you have to do all the detailed config yourself, assuming you have knowledge of Batman, vlans and guest networks.

Speak up if you want the v5 beta, it will be available for download on github if you cannot wait for the release.
