Tried wired connection to laptop?
Here is what I have:
Dell Optiplex desktop with Windows 2000 Pro
Sony VAIO laptop w/ wireless Windows XP Home
U.S. Robotics MaxG wireless router connected to home cable modem
Here's what I've done so far:
Desktop wired to back of router.
Laptop connected to router wirelessly.
I set up a workgroup name.
Laptop can ping desktop.
Desktop cannot ping laptop. arp -a command line executed on desktop shows laptop IP and MAC address.
What else can I do?
