What does the routing table on PC2 look like?  Is its default gateway PC1
or something else?

What do you see when you run "tcpdump -ni wlan0" on PC1 and "ping 
192.168.1.1" on PC2?  Do you see ping packets from PC1 and a reply from
the Velocity?  If you don't see the ping on wlan0, do you see it on
eth0?

Is this just a formatting error in your email?  If this is really what's
in your script, then it's probably why PC2 can't get to anything except
PC1.
