My laptop can't find my house's 5G networks

I've been using my laptop (ROG Zephyrus G14 2023, GA402XU) for quite some time and my 5G network was always working, it was able to connect to it. But a few days ago, my laptop started to be unable to find the network itself; my 2.4G one still works fine, it shows up but my 5G one doesn't work. I've tried everything I saw on the internet, from flushing DNS Cache to factory resetting by deleting all personal files, but it still doesn't show up. It shows up fine on my other devices such as my phone though. Also, my neighbour's 5G networks are showing up as well, so I have no idea what's wrong. Can someone please help me?

Troubleshoot Wi-Fi Network Connectivity
Quick Steps

  1. Check Router Settings:

    • Ensure 5GHz is enabled.

    • Set the 5GHz channel to 36, 40, or 44 for better compatibility.

    • Reduce bandwidth to 20MHz or 40MHz.

  2. Update Wi-Fi Driver:

    • Go to Device Manager > Network Adapters > Right-click your adapter > Update Driver.

    • Alternatively, download the latest driver from the ASUS ROG website.

  3. Reset Network Settings:

    • Open Command Prompt (Admin) and run:

      cmd复制代码netsh winsock reset
netsh int ip reset
ipconfig /flushdns

    • Restart your laptop.

  4. Change Wi-Fi Adapter Settings:

    • In Device Manager > Properties > Advanced, set:

      • Preferred Band to 5GHz.

      • Wireless Mode to a supported standard (e.g., 802.11ac).

  5. Update Router Firmware:

    • Log in to your router and check for firmware updates.

  6. Test External USB Wi-Fi Adapter:

    • If the problem persists, try connecting with a USB Wi-Fi adapter to rule out hardware issues.
