On the 5 GHz band, if the router is set to auto channel select, it always picks a crowded channel and drops out several times a week, sometimes several times a day. When I manually set a channel it is completely random whether the router applies the setting or not, or whether the wifi works at all on that channel (even when it's not crowded).

If I set it to channel 52, the router ignores it and sets itself to channel 36 (which is crowded), and although I can connect to the network, it's not stable. This only happens with 52 for whatever reason.
If I set it to channel 48, the router accepts the setting, but it is impossible for anything to establish a connection to it and according to the wifi listing the network (SSID) frequently disappears.
If I set it to 44 or anything below it takes _forever_ for the wifi to appear in available networks (if it shows up at all) and quite often I have to reboot the router several times before it shows up, and then it's random if it's possible to connect to it.
If I set it to 64 or higher, usually I cannot connect to the network at all through the wifi.

This is on firmware V5.13(AAVF.14)C0 and the router was provided by Hiper.dk

The 2.4 GHz band usually works, but it's so slow it's not of much use.

    Have you tried to scan your environment to analyze the WiFi signal around your home?
    From your description, it is suggested to contact Zyxel's local support team for a further support.

    We're now in 2025, firmware V5.13(AAVF.17)C0

    Problem has returned. For a while, auto channel has worked okay, but the problems with the 5 GHz band have returned as we now have proper summer again, which makes me suspect the router's antennae is incredibly temperature sensitive. When the router is rebooted, the 2.4 GHz band appears in available networks immediately, while the 5 GHz band can take up to 20 minutes to show up, if it shows up at all. According to the router's internal channel scan, channel 36-42 (80 MHz) are extremely busy in my building and when the router is set to auto channel select, those are the channels it always chooses, which makes the wi-fi unstable if it's even possible to connect. It's well documented on other sites that the wi-fi on this router is weak, but I'm talking about being no more than 3 steps away from it and failing to see any sign that the wifi is on at all, despite the router claiming it is.
