Hello @Harirevuri ,
The Google Nest Wifi automatically broadcasts a 2.4 GHz and a 5 GHz wifi connection as the same network name. If your devices are only able to connect to the 2.4 GHz network and you have having issues, a tip is to move your device further away from the Nest Wifi and try to connect again. The 2.4 GHz network is able to broadcast a further signal so moving away from the router will help you move away from the 5 GHz network which may be causing the issue.
Let us know if you have further questions.
