I have a Lenovo ideapad gaming 3 which supports 5GHz WiFi band as I ran the netsh wlan show drivers command in the cmd and the radio types shown indicated that the device supports 5GHz network but I can't see any 5GHz networks in the networks list. Even my router is dual band with 5GHz and 2.4GHz, I can connect to the 2.4GHz fine but can't seem to find the 5GHz network listed. Please help me.
Thanks in advance!

Your router could be using a 5Ghz WIFI channel that your ideapad doesn't support. The allowed channels vary by geographic location.
You can test this by manually setting your WIFI to a channel number below 50. Those channels are universally supported.
It is also possible that you have the security settings on the router's WIFI set to a setting that your Ideapad don't support. Make sure your WIFI is set to WPA2 AES pre-shared key.
It's a small device which sits between your router and laptop to improve the wireless range.
But since you don't already know what a range extender is, I can safely assume you're not using one, so we can scrub that question.

Have you tried rebooting your IdeaPad, then checking available networks again ?

Try rebooting the router as well, but give it time to reconnect fully before trying to use it.

Bumping thread, just encounter this issue in today.

Just ran into this problem with my Lenovo Ideapad Gaming 3. Suddenly 5Ghz won't connect but other devices works fine. It has no problem connecting to 2.4Ghz so it's only the 5Ghz having issue.

Troubleshooting done:
  1. Rebooted Router
  2. Rebooted PC
  3. Uninstall/Reinstall WiFi driver
  4. Changed channel to lower number (router settings)
  5. Change channel width to 40mhz (router settings)
  6. Change security from WPA2/WPA3 to WPA2 Personal (router settings)
What works for me? Changing security from WPA2/WPA3 to just WPA2 Personal. It connects right away. I then reset the security to WPA2/WPA3 and it connects back without trouble.
I also reset all other settings to auto and see if I encounter the issue again.

WiFi driver: Intel R Wifi 6 AX201 160Mhz

First, it is rude to hijack another user's thread, if you have a problem, you should start your own thread. Second your problem may be protected management frames (PMF). WPA3 requires PMF.

Whoops, sorry didn't mean to hijack the thread, but I have the similar device as the OP so I thought I put what worked for me as a possible solution.
