WifiWave2 wireless repeater setup

Thu May 18, 2023 10:45 pm

Hi all,

I apologize if I use the wrong terms or mix them up. I am a decent software engineer, but a noob in networking.

After reading many posts here and other forums and watching almost all YouTube videos, I still don't know how to connect a cAP ax with a hAP ax3 wireless to act as wireless repeater for my wifi networks.
So where did that get me?
Back to you guys.

My current (small) network looks like that:

ISP - Modem -(cable)- hAP ax3

How I want it to look like

ISP - Modem -(cable)- hAP ax3 -(wireless)- cAP ax

I managed to set up the hAP ax3 as a wireless AP, and it works fine for all my wireless devices.
Unfortunately, I need a stronger wifi signal in our living room and I can't run a cable there. So I decided to buy a cAP ax and use it as a wireless repeater to extend my wifi network.

The problem is that after I bought the cAP ax, I read that the wifiwave2 package in ROS still lacks support for four address frames, so it's not possible to simply set it up as a repeater as is possible in the legacy wifi package for the ac models (at least that's how I understand it).
And I also can't downgrade to the legacy package because the chips in the newer ax models don't support the legacy wifi package.

So I am asking for your advice.
I read a post by Amm0 where he seems to have accomplished exactly what I needed. But I lack the skills and knowledge to adapt his solution for my network configuration on the hAP ax3:

Solution: viewtopic.php?t=180369#p990815

Maybe one of you experts can help me to make my cAP ax work as a wireless repeater to extend the WiFi networks provided by the hAP ax3.

hAP ax3 configuration:

Simple:
  • PPPOE-Client via Modem to ISP on ether1
  • VLAN needed by PPOE
  • Network 192.168.1.0/24 on bridge
  • DHCP Server
  • DNS
  • NAT
  • Wifi1 & Wifi2
  • Simple queue
