Hello @usednet ,

Any news  for my question?

I found that interface with mixed mode (80.11 b/g/n) can't accept 802.11g clients

If I configure interface in single 802.11g-only mode - issues is resolve

Hi @usednet 

Can you please confirm if the issue started reporting after the Forti OS upgrade to 7.2.1 firmware?

Hi @usednet 

This is a known issue on FGT firmware 7.2.1 , downgrade Fortigate firmware and the clients will be able to connect. 

Refer to Mantis ID 836216 in the Release notes of Forti OS 7.2.1 ==> Known issues >> WiFi Controller  section (page # 52)

Manasa
