When I upgrade my AP from 4.17 to 5.4 my existing customers running any os from 3.x to 5.4 @ghz 10mhz cannot connect any more.
My AP Wireless Card is set to Mode AP Band: 2Ghz-only-g 10Mhz
Clinets are set to the same thing.
I thought it was my AP so I tried another site and upgraded all the customer cpes to 5.4
When I upgrade the AP to 5.4 again all the CPEs could not connect.
When I downgraded back to 4.17 they connected fine.
