Configuring Linksys WHW03 as Linksys does

WHW03 has 2 ethernet ports, 1 2.4GHz radio and 2 5GHz radios (so 5GHZwifi repeating can be done without 50% bandwidth drop)

The factory WHW03 firmware works great but I hate that I don't have "open" control...

How would one configure openwrt to replicate what Linksys does and calls "mesh" (but from what I've been reading is more likely just fast roaming between APs with ethernet or wifi backhauls) on their firmware with:

  • WHW03_1 in bridged mode withethernet backhaul & 3 APs (1 2.4 GHz & 2 5GHz) with same SSID/security
  • WHW03_2 with 5GHz (fast roaming) wifi backhaul & 2 APs (1 2.4GHz & 1 5GHz) (and same SSID/security as WHW03_1)
  • WHW03_3 with 5GHz (fast roaming) wifi backhaul & 2 APs (1 2.4GHz & 1 5GHz) (and same SSID/security as WHW03_1)

Is it:

  • "Just" bridging all wifi (wether in STA or AP mode) and ethernet interfaces + fast roaming (dawn)
  • relayd (for ipv4 bridging) [+ odhcpd for ivp6] +fast roaming (dawn)
  • 802.11s mesh (mesh11sd, batman-adv)
  • wds + fast roaming (dawn)

This is what the network looks like using factory firmware (or alternatives with one of WHW03_2 and WHW03_3 connecting to the other themselves) and using 2 or 3 5GHz channels depending on its choicies...
