I'm having trouble with my Windows 11 PC not detecting my WiFi network at all. I've tried a bunch of solutions including resetting the network and updating the drivers, but nothing seems to help. Other WiFi networks are visible, but my home network is not appearing. I'm using an ASUS PCE-N15 11n Wireless LAN PCI-E Card with the latest driver, and my router is a Speedport Smart 4. It's interesting because I can connect to other networks without any issues.

Keep in mind that your ASUS card is about 12-13 years old and supports only a/b/g/n standards. You might need to make sure your router is set to use these standards. If your card is configured for a/b/g/n/ax, it could be the issue.
Sometimes, older network cards need a router firmware update to work correctly with Windows. It might be worth checking if your router’s firmware is updated.
I checked, and it’s on the latest version.
It looks like your network card only supports 2.4GHz connections. Make sure your router has the 2.4GHz band enabled; if it's set to only broadcast on 5GHz, your card won't find it.
I've double-checked, and both bands are enabled.

I'm not sure where to change the card configuration. Any tips?
