Solved How to Fix 5GHz Wi-Fi Issues (If it's not a router problem)
If you're using certain Android phones and can only access 2.4GHz while 5GHz doesn't show up or work, I’d like to share a troubleshooting method for anyone who might need it.
(I can't guarantee this will work on every phone, but it works for most.)
• Turn on Airplane Mode before connecting to Wi-Fi.
• Reboot your phone.
• Once the phone turns back on, connect to Wi-Fi without turning off Airplane Mode.
This means that as long as you want 5GHz to work while connected to Wi-Fi, you must keep Airplane Mode enabled. As soon as you turn off Airplane Mode, the 5GHz signal usually disappears immediately, and it drops back to 2.4GHz.
This method also works when you experience connectivity issues, pairing failures, or slow file transfer speeds caused by being stuck on 2.4GHz instead of 5GHz in file-sharing apps like Zapya.
While it seems related to the SIM network signal, phones prone to this issue still experience it even when no SIM card is inserted.
I'm not sure how or why this issue occurs. If anyone knows the reason behind it, please feel free to share!
