My phone is i9300, there are two devices, one is the main route rb951g-2hnd other is rb951-2n, when two devices are connected to a wds state,
Phone can automatically switch the strongest wifi. But when the phone is connected rb951-2n, speed is greatly reduced.
Then I connect two devices directly together with a network cable, wifi useless wds, the phone will not automatically switch to the strongest wifi, how to set the phone will automatically switch wifi, in the case of useless wds.

Use same ssid and different channels.

The effect is not very good, and sometimes will automatically switch, and sometimes it does not.

Switching is done by client. Set more aggressive roaming on his wireless driver or force disconnect by ap when low signal. But I don't recommend the second option.

Thanks reply, it seems there is no way to solve.
