    Lets start off by telling you the hardware that I have:

    1) WUSB54G - Linksys wireless-G usb adapter
    2) WRT54GS - Linksys wireless-G Router with speedbooster
    3) WRT54G - Linksys wireless-G Router
    4) Dell laptop with Centrino/Intel wireless yadda yadda
    5) secondary laptop to be used with usb adapter

    Here's the problem:

    a) when used at the location with the non-speedbooster router, both laptops can connect to the network and the internet with no problems.

    b) when at the location with the speedbooster router, only the Centrino-enabled laptop can connect to both the internet and the network. The usb adapter can only connect to the router, not to the internet or network shares.

    I've updated the usb's drivers, changed network channels, etc., but always get a "limited or no connectivity" warning. Any ideas on what the problem is?

    I've also tried an old 802.11b pcmcia card and it returned the same result. Any help?

    make user that the computer that cannot connect is set to get a ip from the router. make sure the laptop is not set to statsitic ip, and dhcp enabled.

    try to turn off the enrcytion and see if that helps you connect better.

    try the usb adapter on another computer. and see if it can connect.

    I've tried turning off encryption, and that yielded the same result.

    The usb adapter is set to obtain an IP from the server, and the router is set to be a dhcp server.

    still nothin. thanks for the reply though.

    make sure the mac address filter is not on. is there any interference like cordless phones?

    I think the problem lie on the usb adapter. I have wusb54gs at home. And currently facing the sampe problem. Difficult to connect to the router.

    i think that the wusb54g line are all crap. i had one. i found out that when you cut the antennas off the apdater gets better signal. the antennas on the thing is badly designed.

    funny thing is that it works perfectly with a non-speedbooster linksys router.
    there's definately no interference with the telephone, as it is 5.8ghz.

    also, in both windows configuration and the linksys monitor, packets are being transmitted, but not received. Pinging the router returns 100% loss.

    I think jagboy is on the right track but you haven't given feedback on all of his suggestions.

    The symptoms definitely sound like a security related issue. You said you tried disabling WEP/WPA etc security in the router but what about the MAC filter?

    You said DHCP is running on the WRT54GS and that the WUSB54G is configured to automatically obtain an address but you didn't mention whether it actually succeeds. The "limited or no connectivity" warning suggests that it doesn't. I'd be willing to bet that your laptop has an APIPA (169.254.x.x) address when that warning pops up which again suggests a security related misconfiguration. Assuming it is assigning itself an APIPA address obviously you won't be able to ping the router or access the internet. In that case try manually assinging an IP address in the proper range and then see if you can ping the router. (Probably not)

    Are you using the same 192.168.x.x subnet on both networks? If not is there any chance a firewall on the laptop is causing problems when connecting to the WRT54GS network?

    How about jagboy's suggestion of testing the WUSB54G in your Dell after first disabling the built in wireless?

    and try to reset the router completely.
