The o2 Box' reliability and performance has greatly improved with v19.07, but Wi-Fi performance is still questionable.
The RX Rate for most devices is 120 and greater. The maximum combined speed the router is able to throughput via Wi-Fi is around 30 Mbit/s, though.
I already tried to move Wi-Fi to the second core but to no avail. The only way to get decent Wi-Fi throughput is to connect an AP via LAN to the router.
Are there any settings to improve Wi-Fi speed I'm missing, or is this a driver limitation?
