    Dear Networking experts:

    I have read quite a few posts (arguing) on wireless client mode vs wireless ethernet bridge mode. This is my understanding. Can someone reply whether I got this right?

    wireless client: connect ONLY 1 PC to the router's ehternet port. The router connects to a main router (or wireless ISP).
    wireless ethernet bridge: can connect 2 and more PC/devices to the router's ehternet port. The router connects to the main wireless router.

    I have more than 2 PCs connecting to this second router (that connects to the main wireless router). Hence, I probably should use wireless ethernet bridge mode, correct?

    If my main wireless router is at 192.168.1.1. What IP should I set for the wireless ethernet bridge? Do I need to turn on DHCP on the wireless ethernet bridge?

    Thanks!

    Incorrect.

    For both wireless client and wireless ethernet bridge, the radio acts like a normal client to an access point. For a wireless client, the radio link is treated as the WAN. Consequently, the LAN ports will (should) be on a different network, traffic will be NAT'ed, and someone on the LAN side should act as a DHCP server.

    For wireless ethernet bridge, the radio is bridged to the LAN, just as if you hooked two routers together by connecting a cable between a LAN port on each of them. In other words, clients (yes, there can be more than one) on the LAN ports are on the same network as the WLAN, the router does not perform any NAT'ing, and the router typically should not have the DHCP server enabled because there is already a DHCP server for that network.

    Hi, RonWessels,

    Thanks for clarifying my confusion. You saved my day. In my case, I had to switch to WET mode to get everything I wanted working.
