Hello,
I got a TP-Link RE650 running OpenWRT as Routed AP. I followed the official tutorial and the IP4 setup kind of works. (192.168.0.m-Router) -> (SwitchVlan1) -> (RE650-OpenWRT) -> (192.168.1.n-SwitchVlan2/WLAN). The only change on my old router was adding an ip4-static-route to OpenWRT. I am still experiencing that the radios (radio0 and radio1 for both wifi devices) are randomly getting disabled and they are only occasionally powering up. Maybe you spot a problem there. I have to reload network service multiple times till the radios get assigned.
I don't know much about IPv6 but I want to get it running too. My internet connection is dual stack. I enabled prefix delegation on my old router. My first step on OpenWRT was to add a DHCPv6 interface on the same device as the DHCP Client and add it to the same firewall zone. After powering the new interface up it got a IPv6 and IPv6-PD address starting with 2a02 with a prefix length of 64 respectively 62. When going to diagnostics tab and pinging on ip6 it always gets 100% packet loss. Can you please help me with setting IPv6 up? I tried to ignore the failed test and set everything to 'relay mode' in my wlan interface under dhcp ipv6 configuration. In that case the interface doesn't come up at all. I tried to add a new firewall zone for IPv6 which has masquerade = off but this was not successful.
This is the system log when reenabling the DHCPv6 interface:
