Denso BHT-1260BWB-CE User Manual page 135

 Note 
Roaming will be easier and occur more frequently as the absolute value of the roaming
threshold decreases, however, communication may easily be lost as the result of frequent
roaming. Conversely, roaming will be more difficult as the absolute value of the roaming
threshold increases, therefore communication will not be lost easily
When changing the roaming threshold, consider the environment in which the BHT
operates, such as the access point arrangement or electromagnetic noise.

 Note  ・The network connection time and roaming time can be reduced by using only the
necessary bands (uncheck unnecessary bands), particularly when using the DFS bands
(W53 and W56) which require passive scans.
・The DFS bands (W53 and W56) access points automatically alter channels when a
weather radar is detected. This may cause an unintentional disconnection of the
wireless LAN communication or electrical interference.
・Enable the access point function "Broadcast ESSID" and "802.11d"(Country notification)
when using the DFS bands (W53 and W56).
