Does WED increases WiFi latency? According to GL.iNet GL-MT6000 wiki:
WED enables hardware offloading of wireless traffic. The caveat being it will also bypass AQL which may result in higher WiFi latency
I am using AX3000T as an access point (custom build without firewall/dnsmasq). According to this same Wiki, when using devices in AP configuration (routing disabled), in addition to enabling WED, it is also required to install bridger package "(...) which does some BPF (Berkeley Packet Filter) magic to track and offload bridged streams(...)".
Considering I am getting good Wifi performance with AX3000T with WED disabled, I will not change this config for now.
