    My husband and I have a home network set up with two laptops. His is a Dell Inspiron 8100 and mine is a Dell Inspiron XPS. I run Windows XP Pro and his runs Windows XP Home.
    Router is a Lynksys WRT400N Simultaneous Dual-Band Wireless-N Router
    Modem is a Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem

    We upgraded our modem & router a few months ago and haven't been able to get the 8100 to see the XPS, however the XPS can see the 8100. Before the upgrade both computers could communicate just fine and we were able to get into each others "My Documents" folders. I'm sure it's probably something simple, but have no idea how to fix this. We need to get it resolved quickly because we store all of our college documents on my computer, and my husband needs to be able to access them. Classes start on Tuesday! HELP!

    I'd have to say this is probably a firewall configuration issue. My guess is your new router is on a different subnet, and the firewall has not been adjusted to match.

    How can I fix this issue if it is the firewall in my router? As far as I know all of the settings are set to the same as my previous router.

    Disable ALL firewall and Internet Security applications and see if you can ping. Failure to ping is almost always a firewall issue.
