    Hi, As a newbie in networking. I have several problems to ask...

    1. I need to repeat a wireless signal from a certain AP so that my notebook can also get that AP's signal. How can I do it with tomato?

    2. As I change the mode into wireless client, I found out that the WAN port's MAC address will switch into the one used by wireless interface of the router. My question: How can I select the AP to be connected (wirelessly) to the router in this mode? How many ways can my notebook be connected to the router with this mode selected?

    3. What is wireless bridge mode for? I can see that the WAN interface will be automatically disabled with this mode be selected.

    4. What is the difference between WDS and AP + WDS mode? What are their function? The only difference I found is that my notebook can still find my router wirelessly with AP + WDS mode enabled, not so if only WDS mode is enabled.

    Thank you so much for your help :D

    Your best bet is to use AP+WDS mode. Looking at the Tomato FAQ for instructions on how to set this. You will want both your main router and your "repeater" to be in AP + WDS mode.

    If you set your "repeater" to WDS mode, it will serve as a bridge only for computers that are plugged into its LAN ethernet ports. (Don't plug anything into the WAN port!) Computers will not talk to the repeater wirelessly.

    Wireless bridge mode is very similar in function to WDS mode, but it is implemented using a more standardized protocol. Like WDS mode, it allows computers that are plugged into the LAN ethernet ports to talk to the router. Whereas setting up a WDS repeater requires the cooperation of the router (it also has to be in WDS+AP mode), setting up a wireless bridge can be done unilaterally. You can set up a wireless bridge to a router that you don't own, for example.

    The implementation of wireless client is that the WAN port is the wireless interface. In general, you don't need to worry about the MAC addresses unless you're doing something specific.

    I hope I've answered your questions.

    There's an old thread here that talks about the various different wireless modes in Tomato. Be aware that the term "Wireless Bridge" is often used for different concepts, and different software will have different meanings for a "Wireless Bridge" mode, which can cause no end of confusion.

    What I don't understand now is how to select the AP to be connected to my router in Wireless client mode. In WDS, I can set the MAC address of another router in the field provided. What about in wireless client mode?

    In bot wireless client mode and in wireless ethernet bridge mode, you set only the SSID, the channel, and encryption. The router finds the base station the same way your laptop or any other wireless device does. If you happen to have multiple routers (via WDS) with the same SSID and channel, then the wireless client will pick the one that has the strongest signal.

    Still confused, I'm sorry...

    Okay, here is the example.. Here, near my room, There are two access points..
    Let's say the SSID is A and the other is B.. In wireless client mode, How can I choose the SSID A to be connected to my router?

    fyellin's answer was perfectly clear imho besides which, you answered your own question..
    "How can I choose the SSID A to be connected to my router?"
    Answer: by typing "A" in the SSID box rather than typing "B"!?

    Which box are you talking about? Is it the same box in which I should type my router's SSID in AP mode?

    This field indicates "This is the wireless network I want to be a part of". What you click elsewhere on the page (see previous posts) indicates what role you are playing in this wireless network.

    Hmm, Maybe a screenshoot would be great..
