i've a situation where i can't associate to the lightweight ap near to the pc but is able to associate to other laps in the 4th and 3rd floors. when i try to remove the mac from the lap (via the wlc), it just transfers to another lap but not to the one i'm near at.
i disabled the radio of the far laps from 4th and 3rd floors where the pc is hopping from. finally it got associated to the supposed lap, and the signal from this is 'Excellent'.
The signal from the 4th and 3rd floor, when the pc is connected, is really weak, compared to when it is connected to the nearby lap. about 2 bars on the status.
after i enabled the radios of the laps, the pc associated back to the lap in the 4th floor, which is having 25 (level 3) of power and on channel 6. the channel of the nearby ap is 11. and having the same power level (3).
any ideas why this is happening?
