I can't seem to get my network configured.  I formatted my computer, SET up the network with the wizard and it installed a residential gateway under network devices.  None of my other COMPUTERS can see my network, norcan I see the other computers.  Now the residential gateway icon is gone from network devices but the when I run the network wizard it AUTOMATICALLY comes up with a check in the box that says: THIS COMPUTER CONNECTS TO THE INTERNET THROUGH A RESIDENTIAL GATEWAY OR THROUGH ANOTHER COMPUTER ON MY NETWORK.  When I check the box showing this computer connecting directly to the internet and all other computers on my network connect through this computer, it cannot complete the wizard.  This tells me even though the residential gateway isn't listed in network devices, it still thinks it's there.  This isn't the first time I've set up this network, I just happened to build a new computer and had to re do it.  Can I somehow take the settings to default windows config and try to reset it up?  The ROUTER I'm using is Netgear WPN824v.2. Is it a wireless or ethernet connected network you are setting up?
Did you change the workgroup name in each computer to the same network name?
Are you using windows xp PRO?
