    Hi all

    I'm in the process of setting up my wireless network and having some real problems. I'm using an ADSL2MUE modem, connected via Ethernet to a WRT54G wireless broadband router.

    I can get access to the Internet etc. when I'm running them hardwired to my PC (ethernet from PC to router) but am having problems running them in wireless mode.

    Here's how things are setup:

    Modem - IP address of
    Router - IP address of
    PC Ethernet - IP address of, default gw (interface to be disabled once the wireless network is working)
    PC Wirless - IP address of ?.?.?.?, default gw ?.?.?.?

    What settings do I need to put into my Wireless adaptor (also Linksys) to get Internet access?

    Thanks in advance,

    Is the WRT54G set up as a DHCP server and is there an encryption, MAC Address filtering on the router? Which operating system do you have and at what service pack level? If the WRT54G is setup as an DHCP server the Linksys Wireless adapter can be set to obtain its setting automatically (i.e. DHCP client). You did not indicate which Linksys Wireless NIC you have. If you have Windows XP make certain you have the Windows Zero Configuration service automatically started at startup and do not use the Linksys Client Software. This will enable you to see your wireless network.

    If you have MAC filtering enabled on your router, the MAC address of your NIC has to be entered in the list of PCs that are allowed to access the Router,

    You can set the cahnnel on your NIC to match that of your router, or use WZC to set the channel. You should have changed the SSID of the router from Linksys and changed its default password from "admin" and you should have used either WEP or WPA-PSK for encryption. WPA-PSK is only avail with Windows XP SP2 or Windows XP with a hotfix.

    Use the same key length and key on both router and the wireless NIC.

    Ok, here goes:

    The WRT54G is setup as a DHCP server but whenever my Wireless NIC tries to connect to the wireless network it fails to get an IP address.

    I have a WMP54G Wireless NIC.

    I'm running WinZP SP2 and have Windows Zero Configuration service running automatically.

    I have WEP encryption on my wireless network but that is it - no MAC address restrictions etc. Both the router and the NIC are running on Channel 11.

    Doh, managed to get it working. :oops:

    To cut a long story short, I had the Wireless NIC configured with the value for WEP Key 1, when it was looking for the value of WEP key 3.

    All now working, problem solved!
