wifi: force connect to 2.4 wifi instead of 5G

[Lbjailer]

I just got my S25. I need to connect to the 2.4Ghz wifi instead of the 5G. I have devices to setup on the phone that requires initial setup to use 2.4 and the 2.4 does not appear in the available connections. 

The 2.4 SSID is broadcasting but does not appear in the wifi connections on the S25.

I got it to work. I had to forget the SSID, turn off the wifi on the phone and then reconnect to network.
