WDS, VLAN and Fast transition

AMWN · April 24, 2020, 12:44pm

Hi, I'v got a situation on which I need some advice.
I want to extend my current network with an acces point (WDS).

This is my current setup"
I'v got 3 TP-link Archer C7 with openwrt 19.07.2.

- Main Router
  VLAN: LAN(1), IOT(2)
  WIFI: AMWN (2.4Ghz), AMWN-5G (5ghz, WDS AP) and AMWN-IOT (2.4ghz, WDS AP)
  Interface: WAN, LAN (AMWN, AMWN-5G) and AMWN-IOT (2.4ghz)
  802.11r Fast Transition enabled
- AP1
  WIRED
  VLAN: LAN(1)
  WIFI: AMWN (2.4Ghz), AMWN-5G (5ghz)
  Interface: LAN (AMWN, AMWN-5G)
  802.11r Fast Transition enabled
- AP2: WIRELESS REPEATER (WDS)
  VLAN: LAN(1), IOT(2)
  WIFI: AMWN-5G (5ghz, WDS client, AP) and AMWN-IOT (2.4ghz, WDS client, AP)
  Interface: LAN (AMWN-5G) and AMWN-IOT
  802.11r Fast Transition enabled

Questions
The questions are about the extending my network with AP2. Old situation with main router en AP1 everything works fine.

I created a network bridge (repeater) over 5ghz connected to AMWN-5G. Next I made an acces point on 5ghz to extend the wifi with same SSID with help of this guide. I could only get is to work on fixed channel 149 which is ok, but took some time to figure out.

Sometimes connected devices do not have internet connection, probably after switching acces points. After reconnecting to same network problem is solved. What could be the cause?

I also want to extend the IOT network, for better coverage for my iot-devices. I created a network bridge (repeater) over 2.4ghz connected to AMWN-IOT. So I also made VLAN iot, interface and bridged AMWN-IOT, static IP in de range of IOT subnet. DHCP disabled etc. For testing purpose I used a different SSID (openwrt) for the AP.

On this network the devices won't receive an IP-adres. What could be the cause?

Is it possible / usefull to also create a bridge over AMWN (2.4Ghz) besides AMWN-5G for better performance?

Thank you for your time!
