  Wireless roaming is one way to improve the reliability of a network of
hotspots that are still using the topology Basic Service Set (BSS). When the
user walks away from one access point (AP) or one AP die then begins to lose
the signal, the mobile station (MS) is automatically connected with the AP to
another without reconfiguring. Devices that support wireless roaming is the AP
TP-Link TL-WR740N using DD-WRT firmware that supports DHCP forwarder. Wireless
roaming makes it easy for the user if there is more than one AP in an area.
