    Here's the topology...

    There's an always-on desktop running XP Home on the LAN. This desktop is connected to the LAN via a US Robotics USB Wifi Adapater. It's an adapter that sits on top of the tower and is plugged in via USB. This desktop is where i store my mp3s and videos and what-not.

    I have a notebook that I connect to the LAN with wirelessly or sometimes via ethernet cable; the wifi card is in Intel 2200BG. I have no problems connecting to the LAN, seeing the desktop/shared folders, or getting on the internet with the 2200BG.

    However, when i jack into the router via an ethernet cable (wifi is off), i cannot see the desktop. Hitting the web is no problem, but if i browse to the Workgroup, i can only see my computer, not the desktop. If i try to just map a drive, type in the IP addy, etc., it doens't work. i can't even ping the desktop.

    The router in question is a Trendnet Wifi Router running at G speed.

    Any ideas? I would like to be able to transition between both wifi and ethernet effortlessly, but i'm having LAN problems with the ethernet connection.

    Is the firewall turned off on the desktop and the laptop?

    firewall is turned off on both desktop and notebook.

    it's gotta be something very simple. the only difference between the wifi and wired connection is that i can't see the other computer on the LAN when wired.

    yeah, i'm pluggin into the back of the wifi router...

    oh, another difference, obviously, is that i'm assigned a new IP... when wireless, i get .0.2 and when jacked in, i get .0.5, but everything else is the same; same subnet, same gateway, etc.

    Try switching it over to .1 on the laptop, and .2 on the desktop if possible,

    I would also try to renew your IP addresses for each computer in the command prompt

    Maybe update the firmware for the router

    Try making the network through the Windows XP setup again


    I hope it works for you Drumfu, it must be fustrating

    Another thing to try is to go into the properties of the network card and set it specifically for 100Mbs/Full Duplex. I've had issues with some Windows configs where the card was set to Auto.
