(While wireless network has become the preferred solution for families and small and medium-sized enterprises to establish networks, because the houses are basically reinforced concrete structures, and the patterns are complex and diverse, the environment has serious attenuation of wireless signals. Therefore, when using a wireless AP for wireless network coverage, there will be signal difference, the data transmission rate can not meet the needs of users, and even the problem of signal blind spots. In order to increase the coverage of the wireless network, increase the long-distance wireless transmission rate, and make it convenient and fast to surf the Internet by using wireless in the distance, we need to use the bridging or WDS function of our wireless router.)
