Any reason you didn't bother to disclose the make and model of the
router? Unreleased product or too small type size?

Which firewalls and anti-virus programs? I've had far too much
entertainment value trying to convince Norton's Internet Security
Firewall to turn off and stay off. The Windoze XP SP2 firewall turns
off nicely but do check the Exceptions tab and make sure ping is
enabled.

I wish I could do that. For some reason, my eyes can't see 2.4Ghz.
I'll ask the optometrist if he has a fix.

Can't ping usually returns some kind of error message such as "no
route to host", "interface down", or some configuration error message.
What error are you getting when you try ping?

Do these "other machines" have an ethernet wired port? If so, forget
about wireless for the moment and see if they work via a wired
connection. That will eliminate any firewall, anti-virus, or parental
control issues. If it works, unplug and continue troubleshooting the
wireless. If not, fix the XP SP2 configuration.

Any chance you have MAC address or IP address filtering enabled in
your unspecified wireless router? Is so, turn it off for now. If you
feel ambitious, just do a grand reset and start over on the router.

You've apparently used fixed IP address on the clients. What did you
use for a gateway? Hopefully, it's 192.168.0.1. Make sure by
running:
Start -> Run -> cmd <enter>
ipconfig
Strictly speaking, you don't need a default gateway for ping to work,
but it does help in getting to the internet via the router.

Also run:
ping 192.168.0.1
arp -a
and see if it returns a proper MAC address and IP address pair.

Other useful commands are:
tracert 192.168.0.1 (where are my packets going?)
route print (where are my packets suppose to go?)
netstat -rn (same as above)

You didn't mention the IP of the laptop. Is the laptop's TCP settings
configued for DHCP? Is the APs DHCP server turned on?
