Destination Host Unreachable

R

Ray

I have a desktop, connected to a Belkin wireless router. I have a
laptop with a wireless card. The two have been in touch in the past.
Somewhere in the shuffle, they stopped speaking. Now when I ping the
laptop's IP address, I get "Destination host unreachable." The laptop
sees the router and reports excellent signal strength. Device Manager
reports no problem with the network adapter or anything else. What
could have happened to kill the connection - or why doesn't My Network
Places on either machine see the other?

Ray,

P4 is running Teredo Tunneling aka IPV6. Please remove that, at least to see if
the problem is related to its presence.
