You're saying "client". Are saying there is only ONE wireless client having issues?

So when the 2.4 Ghz of an AP is turned off, the client goes to another AP and joins another 2.4 Ghz?

1. Is 5.0 Ghz turned on?

2. What antenna are you using for the 2.4 Ghz and 5.0 Ghz?

1. Is 5.0 Ghz turned on? yeah 5GHZ is turned on

2. What antenna are you using for the 2.4 Ghz and 5.0 Ghz? for both the radios it is internal radio
