Just installed an AXE5300 setup and was trying to find the 6Ghz network to see if I can utilize more of my gigabit fiber bandwidth. I've setup the 6Ghz signal to be backhaul and wifi and I'm using an iPhone 13 Pro which is Wi-Fi6 capable, yet I'm not seeing a 6Ghz network available to join. I've tried inputting the name manually, but that didn't work and I've rebooted both the router and my phone. What else should I do?
