I used nc and telnet from my laptop and this is what I get when I try to connect:
Code:
telnet 192.168.3.16 80
Trying 192.168.3.16...
telnet: Unable to connect to remote host: No route to host
nc -nv 192.168.3.16 80
(UNKNOWN) [192.168.3.16] 80 (http) : No route to host

my routing table on my laptop
Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.3.1     0.0.0.0         UG    0      0        0 wlan0
192.168.3.0     0.0.0.0         255.255.255.0   U     0      0        0 wlan0

what is it that I am not seeing?

unreal, I finally figured out why there wasnt any icmp and anything else showing up in my wireshark packet. I have a Zyxel AP that connected all of my wireless devices and it had a setting:
Code:
Enable Intra-BSS Traffic 	Intra-BSS traffic is traffic between wireless stations in the same BSS. Select this check box to enable Intra-BSS traffic.

which was unchecked and without that enabled you cant route any traffic between workstations within the same subnet. Crazy but that is what is was. I guess it would be used for situation where only strict route rules would be set to enforce greater security protocols in place in a network that would use these type of AP. I would imagine Cisco and other corporate AP would have the same type of security features. Wow I truly learned something new. DGPickett your awesome and thanks for sticking this out with me.
