AP client router vs. AP router modes: request for clarification

    Hello,

    I am trying to configure a Linux based home router (TP-Link TL-
    WR743ND). In the manual it says:
    http://www.tp-link.com/en/products/details/?categoryid=241&model=TL-WR743ND

    "The Router supports two operation modes for multi-user to access the
    Internet: AP client router and
    AP router. In AP Client router mode, it can access the Internet
    wirelessly by your WISP’s support. In
    AP router mode, it can access the Internet via ADSL/Cable Modem. You
    can configure your
    device quickly by the following steps in different modes."

    The home router has a wired RJ45 connection to the antenna on the roof
    (one of the LAN ports on the
    router is used, not the WAN port on the router, not sure what the
    exact difference is). The antenna
    on the roof also uses ADSL (as advertised). There is no BNC or RJ11
    jack on the home router.

    So I am using a WISP but am not accessing it wirelessly. I guess this
    means the home router is
    configured in AP router mode and not in AP client router mode.

    On the other hand I am not using the WAN port, which seems to imply I
    am using the router in
    AP client router mode and not in AP router mode.

    Then on the web page above it says
    "WISP Internet connection provides local network sharing wirelessly or
    via cables"
    but I thought the W in WISP stands for wireless (information service
    point), does it
    not (at least it does according to wikipedia)?

    Here comes my question:

    Why connecting to the ISP wirelessly called AP client router mode and
    the wired connection
    called AP router mode? How does the word "client" make the difference
    between a wired and
    wireless connection?

    Can someone point me in the right direction? I am confused.

    Thanks for the clarification,

    John Goche

  2. When using a wireless connection to the isp, the access point (radio) is
    a client of the isp's wireless network.

    Then using a wired connection to the isp, the access point is acting as
    a router for wireless devices that connect to it.

    Thank you Dave for your clarification. I wonder whether you could also
    kindly help me with the following WPS (Wi-Fi Protected Setup) problems
    I have been experiencing (tried posting but got no reply so I thought
    I would post again):

    Yesterday I had three laptops connected via WPS
    (Wi-Fi Protected Setup) to a TP-LINK TL-WR743ND
    wireless router. Things were working fine when today
    as soon as I disconnected from any of the three laptops
    I could not reconnect without first pressing the WPS
    button on the router. The problem is that the router
    is some distance from two of the laptops. Does anyone
    know how it is possible that I had to press the WPS
    button _again_ for my connection to be accepted even
    though the router's password and other settings had
    not changed. Now I can disconnect and reconnect without
    having to press the WPS button, but since I don't
    understand how come I had to reboot and press the
    WPS again this morning to get things to work I am
    afraid I might have to do this again in the future.

    1. Can anyone shed some light on why I may have had
    to press the WPS button again?

    2. Now I am trying to connect to the router via WPS. At
    the moment this requires pushing the pushbutton on the router
    prior to connecting. I would like to be able to connect by entering
    a PIN into the router or pressing a pushbutton on the laptop
    that connects to the router. Alas, my laptop is brand new but
    I see no hardware pushbutton (is there a software pushbutton
    somewhere)? I cannot even find a PIN on my laptop (I can only
    see the router's PIN via HTTP from another laptop).

    I don't want to have to push the push button on the router every
    time I disconnect from a laptop and reconnect.

    Is there a software way to reveal the laptop's pin or push
    the pushbutton under Linux?

    How should I proceed?

    Suggestions welcome,

    Thanks,

    John Goche

  4. While I've seen similar connection protection methods with things like
    bluetooth, or optical mice/keyboards, I had never heard of it being
    used for wi-fi devices till I saw your first article, and ran a search
    on it.

    I expect very few people here have any experience with WPS.
