Occasionally certain gadgets can only link to a temporary guest network.
Hi everyone, I own an ASUS RT-AX82U and recently faced issues where certain gadgets couldn’t join the network. It’s a mix of my LG C2, iPhones, Android phones, and they all worked before but now show “unable to join network.” I’ve tried powering off modem and router for half an hour, then restarting them without success. Updated the router firmware and reset it to factory settings, but nothing changed. It seems everything was fine previously. I split the network into 5GHz and 2.4GHz bands, yet devices still can’t connect. Disabling Wi-Fi 6 mode helped temporarily, though it’s not a long-term solution. Enabling guest network worked once, but now accessing printers and other shared resources is impossible. All wired connections are stable, and my two Windows laptops connect without trouble. Also, turning on “Access intranet” for the guest network prevents devices from connecting again. Any advice would be appreciated—I’m really stuck.
Show a screenshot of your router's WiFi configuration for both 2.4GHz and 5GHz bands. For all affected devices, reset the connection profile and reapply it. Older gadgets often handle profile changes better once set than during initial setup. For example, some smart TVs that only work on 2.4GHz may struggle with 40MHz channel widths, while those supporting 5GHz typically detect only channels 36-48 (non-DFS).
