Need help troubleshooting new wireless network

By taraleeriley ·
I've set up a wireless network using WGR614 Netgear Wireless Router.
We have a DSL connection to our internet provider. I have a desktop
running Windows XP and a brand new laptop running Vista. Both
computers can get onto the local network without an issue. The
laptop is using a built in wireless card and the desktop can use either
the hard wired ethernet cable or a wireless card. However the issue
we have is that they can't both get access to the internet at the same
time. The laptop running vista can get the network and internet if the
desktop is not connected to the network at all. Once the desktop is
connected the laptop no longer gets internet. The internet on the
desktop is flaky at best.

I'm not sure what to do now. I'm not a networking person and i'm at
my wits end! Does anyone have any suggestions?

Thanks in advance.

Was the desktop connected directly to the dsl modem previously? Does it have an assigned IP address or does it get it dynamically from the router? Does the DSL modem have any routing functionality and possibly is issueing the same IP address range as the new router? Try changing the IP address on the local netwrok side of the new wireless router from to to rule out the last possibility.
