iPhone not connecting to 2.4Ghz only now (5Ghz works fine)

[billion_fan]

This is still not working sadly on the 2.4 Ghz band ... if I turn off encryption it connects fine but when encryption is on my iOS devices wont connect and keeps saying incorrect passphrase...

Any thoughts on encryption settings?

1. Have you tried to forget the network on your ipad and then reconnect?

2. Also try changing the SSID again.

3. Also try disabling the 'Private Wi-Fi Address' option on your iPad

Also the 'Network Authentication' should be 'WPA2-PSK' with 'WPA/WAPI Encryption' set to AES

Tried all of that already to no avail. It worked temporarily after charging the ssid but a few days later back to the issue. Most bizarre.

I’ll try again with the new iOS out and see.

For my 2.4G I have the following set, and that works fine for iPhone/iPod/iPad:
Network Authentication: WPA2-PSK
Protected Management Frames: Disable
WPA Group Rekey Interval: 3600
WPA/WAPI Encryption: AES

Ive changed SSID , Channels & played with settings but the iphone (and any other device) cannot connect to the Unit. The same result comes back
"Failed - Incorrect Password"

Any help much apprecaited 52d firmware. 5G wifi works fine fwiw - but one key device cannot connect to 5G wifi only 2.4

More bizarely this is a brand new 8900 although using the settings saved from my old unit where I also had this issue.

Try a factory reset for a test, and use a new SSID and password for the 2.4ghz, try it keep it simple for the password, no special characters, just letters and numbers.

Ill try - but I think the unit picking up interference - Ill relocate as well.
