Additional info:
This is a Belkin wireless G router, model/firmware F5D7230-4_US_8.01.21, running in "access point" mode.  Cable is connected to LAN port on device, and I am pinging the LAN side address of the device (192.268.1.250) from 192.168.1.110 and 192.168.1.101.  No NAT is involved.  iptables and selinux are disabled.

I have other routers and access points on my network.  I can ping them all successfully.  I can ping this device successfully from Windows machines on the same network.

I can successfully ping via "arping" from Fedora, and I can telnet to port 80 on this device from the Fedora machines and all others.

This device was pingable previously, but occasionally failed to respond causing Nagios to erroneously report failed services.  Since replacement of machines and upgrade to Fedora 13, neither of my Fedora 13 machines can successfully ping this device.

I have tried different network interfaces and different IP addresses, nothing changes.  Everything works, EXCEPT ping from the Fedora machines.  I'm mainly opening this issue because this problem is so bizarre, I'm hoping for SOME explanation.  Ping does not seem to have any diagnostic mode that I can identify.
