rickity,
It's a little confusing:
I can ping all around the local network with all the other PC's and Laptops ( all windows) but not from the PI
wired ethernet pings appear ok
Is it just wireless you have a problem with??
Since you've got a packet analyser to hand, what do you see when you ping from the pi to a local address? Do you see packets sent out? Do you see responses, even if the rpi doesn't get them? Can you look at traffic on all the switch ports (monitor port)?
Does the rpi respond when pinged by something on the LAN?
Have you got both wired and wireless going at the same time (and have they got different IP addresses)?
What does the ARP table look like, both for a Windows PC pinging the rpi and vice-versa? Troubleshooting this might come down to MAC layer.
