The difference between wireless bridge and relay modes
Wireless bridging, also known as WDS (Wireless Distribution System, wireless distribution system ), is divided into two modes: Repeater (relay mode) and Bridge (bridge mode), both of which can amplify existing wireless signals to expand the coverage of the wireless network;
Repeater
As the name suggests, a relay receives signals while transmitting its own wireless signals. That is, client+AP mode. In this mode, the wireless router accesses the wireless signal transmitted by the main AP as a client, and then uses new virtual interfaces ( Virtual Interfaces) to provide wireless access to the client. The greatest significance of this mode is that it can solve the problem that wireless signals cannot be transmitted farther due to distance or obstacles. In this mode, the wireless router still provides DHCP and NAT functions, that is, all internal LAN ports and wireless client access constitute a separate LAN segment.
Application scenarios of relay mode in the network:
The IP pool of the main route in relay mode is: 192.168.1.100~192.168.1.200
Then the relay router needs to set the IP of the WAN port to the IP in the IP pool.
Then set the IP pool of the LAN port to other network segments, for example, you can set 192.168.2.1~192.168.2.100, etc.
As long as it is not in the same IP segment as the main route.
Relaying is equivalent to using wireless as a secondary route. Of course, the secondary route is called wired, and wireless is called relay.
Bridge (Repeater Bridge)
is the same as "Repeater" mode, which can solve the problem that wireless signals cannot be transmitted further due to distance or obstacles. However, the computer terminal connected to the wireless router is in the same IP address segment as the main wireless network. Internal DHCP requests will also be forwarded to the main wireless network.
Application scenarios of bridge mode in the network:
The IP pool of the main route is 192.168.1.100~192.168.1.200.
Then the LAN IP address of the bridge route needs to be set in the IP pool of the main route, that is, 192.168.1.2, etc., and then turn off DHCP.
The downstream terminal of the bridge router will automatically obtain the IP assigned by the main router.
