Roaming client (hard question) :(

Lets say i have a client

in the other side 2 access points each one of them are repeating a third access point

e.g : 2 access points in repeater mode A and B , both of them repeating a signal from an Access point C

Now the client is near the 2 access points A and B but can't see the C
The client will access one of A or B .
what happens if the link between A and C gets weaker as bandwidth will the client swap to access point B or it just stay connected to A cause both A and B for the client have the same signal and same bandwidth between each other ?

I know it might be silly question but i love to know things that i have no answer to it

The client won't automatically jump to the stronger AP. It will hang on to the initial one, regardless how weak the signal is, until it entirely looses the connection.

"It will hang on to the initial one, regardless how weak the signal is, until it entirely looses the connection"

I dont think so ! when i use the ipad lets say and roam between access points , it change AP when the Threshold go below it. and i roam in less than 200 ms .which means my wifi wasn't droped because if that was the case the ipad would need more time to reconnect to the repeater . so i am sure it does roam when signal is low .

But my question is different than this signal strength issue
