Cannot ping one machine

I've been scratching my head over this problem for a week now, but
maybe someone has some new ideas.

I have a bunch of computers, they are all on the same subnet, but a
couple are connected through a WiFi (D-Link DWL-1000AP/dwl-650) net
(802.11b). The problem occurs wether or not I use DCHP or assign
static IPs.

All devices have the same gateway x.x.x.1 and subnet mask
255.255.255.0.

Computer: x.x.x.1 Connected via cable to hub
Computer: x.x.x.61 Connected via cable to hub
WiFi Airport: x.x.x.62
Computer: x.x.x.63 Connected via WiFi net.

This is the scenario:
x.x.x.61 can ping all IPs on the subnet and get an answer back. This
includes computers on the WiFi network.

x.x.x.1 can ping all IPs except for x.x.x.62 and x.x.x.63 (the
computers and airport of the WiFi network).

x.x.x.63 can ping all IPs except for x.x.x.1.

Any ideas anyone?

Do you have some sort of MAC filtering enabled on the WiFi Airport?
My guess is the computer at address x.x.x.1 is not configured as an
allowed host in the MAC filter table.

I changed the setup and I still have the same problem.

x.x.x.1 Computer connected to hub
x.x.x.2 Computer connected to hub
x.x.x.60 WiFi AP (DWL 1000AP)
x.x.x.61 WiFi Laptop
x.x.x.62 Laptop connected to hub

Both x.x.x.2 and x.x.x.62 can ping everything on the subnet (hub and
WiFi computers).

The exception is x.x.x.1 which cannot ping anything on the WiFi net.

All WiFi devices can ping everything on the subnet with the exception
of x.x.x.1 which cannot be reached.

How can the wireless net be reachable from x.x.x.2 and x.x.x.62, but
not from x.x.x.1? They are all on the same subnet and x.x.x.1 can
reach x.x.x.2 and x.x.x.62 without problems.

Any Firewalls setup?
