The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each AP
to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:

received by the wireless station is too worse, Vigor router

requirement) and cut off the network connection for that

get better signal.
