    Hi @Milaluna

    If 5G work but 2.4G doesn't work, you need to check the channel utilization.

    If the channel utilization of 2.4G is high, it will cause your wireless network unstable. Please try change to channel to DCS mode and do to DCS now to change the 2.4G channel.

    Additionally, the suggestion above is based on the current information you shared. If not help, please share more details about:

    1. How 2.4G did not work?
    2. What end device got issue?
    3. What was the issue event log?

    If your AP is using Nebula mode, please share your organization's name and enable Zyxel support access so we can check further.
