WRT54G Wireless IP Problem

    I have a Linksys WRT54G router set up as a switch (I am on a network that already has a router set up handing out private IP's). DHCP is disabled, and the Linksys is set to 'router' instead of 'gateway'. I plug directly into it with an ethernet cable and all is well. My roommate is set up to use the wireless side of it, and he connects fine. However, my laptop that has a wireless card connects to it, but does not get the proper IP. This is the same laptop that I can use to connect via an ethernet cable.

    The wireless card is a Broadcom 802.11 b/g card, and I even installed the drivers that came on the Linksys CD, but to no avail.

    When I do an ipconfig, I notice that it isn't even pulling the correct IP range:


    Ethernet adapter Local Area Connection:

    Connection-specific DNS Suffix . :

    Ethernet adapter Wireless Network Connection:

    Connection-specific DNS Suffix . :
    Description . . . . . . . . . . . : Broadcom 802.11b/g WLAN
    Physical Address. . . . . . . . . : 00-90-4B-93-A5-F5
    Dhcp Enabled. . . . . . . . . . . : Yes
    Autoconfiguration Enabled . . . . : Yes
    Autoconfiguration IP Address. . . : 169.254.106.244
    Subnet Mask . . . . . . . . . . . : 255.255.0.0
    Default Gateway . . . . . . . . . :

    The wireless settings are set up to receive via DHCP, just as the ethernet connection is. Yet for some reason it pulls this default IP scheme.

    Am I missing something here?

    169.254.106.244 is an auto generate address. It must not be connected to the AP. Are you using the Ithe Windows zero wireless service or a Broadcom wifi client? Double check your SSID configuration as it may not match up.

    Also, which edition of Windows are you running?

    Thanks.

    The SSID is correct in my settings, and I have the correct WEP key in use. But for some reason it says that it is connected to my wireless network (the little bubble displays the correct SSID). But it's still using the wrong IP. Thoughts?

    When you're testing your notebook with wireless, do you still have the wired connection connected? If so, you should disable it first or remove the cable. It appears that your Realtek connection is grabbing the IP.

    If you have that wired connection set with a 'hard' IP (fixed), that could be posing problems as well.

    Try connecting without any wireless security and see if the problem persists.

    I would also try to re-enter the WEP key and make sure it has been entered correctly.

    *To avoid confusing, return settings as default.
    : Reset rouer or use factory default option.

    1) check up your WIRED settings again.

    - for wireless setting
    a. Wireless > Basic wireless settings : change SSID
    a-1. If you want, set up wireless security as WEP or WPA-personal(PSK)

    - for setting up as a switch
    a. Setup > advanced routing > mode : set as 'router'

    b. Setup > basic setting > dhcp server : set as disable.

    b-1. What is the LAN IP address of other router on your network?
    Is it '192.168.1.1'?
    If yes, change LAN IP also as like 192.168.1.254 or 192.168.2.1 etc.

    *Just remember, DO NOT SET A SAME IP ADDRESS WITH OTHER ON THE SAME NETWORK.

    b-2. If not, Never mind regarding LAN IP of WRT54G.

    c. Use only LAN ports


    2) check up your WIRED connection.

    - Ethernet adapter (Local)
    a. set it as Obtain IP

    b. renewal IP then check IP address : ipconfig/all on command prompt or status of Local network connection

    b-1. If PC get an IP from upper router(DHCP server) and can get online.
    WRT54G set it as Switch/AP mode correctly.


    3) check up your WIRELESS connection.

    - Ethernet adapter (Wireless)

    *If you use only one PC what has ability of wired and wireless network, remove ethernet cable from your PC or disable local area connection.

    a. set it as Obtain IP

    b. search wireless signals.

    b-1. If you use windows XP's Wireless Zero configuration (WZC),
    Run 'View available wireless networks'

    b-2. If you use other WLAN application, follow instruction of mannual of Wireless network adapter mannual.

    c. If SSID is detected, try to connect to it (defined SSID by yourself.)

    c-1. It's first connection trial, so You should enter connect 'Network KEY'.

    c-2. If It is connected, check IP address : ipconfig/all on command prompt or status of Local network connection

    c-2-1. If PC get an IP from upper router(DHCP server)
    and can get online. Your Issue is solved.

    c-2-2. If not, retry after disabling wireless security.

    d. If SSID is not detected, check what error message on WZC is.
    d-1. If 'Windows can't config wireless... ' : Use your 3rd WLAN application.

    d-2. If 'No SSID is detected in wireless range' : Check your wireless network adapter on 'Device manager' option.

    d-2-1. If it working properly. check or make a new profile on wireless network adapter. then retry 'searching SSID'
    **If you use 3rd WLAN application, you may stop WZC on windows service list.
