@Kevin_Z as the channels aren't showing above 48 so tried all the channels from 36 to 48 but that doesn't worked. I tried with devices like my phone samsung a31, redmi note 9, oneplus 6T and laptop...

@Kevin_Z thanks for the reply Followed all the things you have mentioned but still i am not able to see my 5ghz network in the wifi list. Tried all the other devices to verify but the problem doesn't...

@Khurram731 same issue with me, from the past 4-5 days 5GHZ is showing but i am not able to connect to it
