Problem connecting via wireless access point

[lio_013]

Hello every body
i ahve just installed fedora 11 kde edition and i used to use fedora 10
after finish installation i edit the connectons to connect to my network im in lan network
but i connect my cable to an access point to free using my laptop anywhere

after adding every thing (wep key ,static ip's,.......) as i used to do and i have the connected sign at the system tray
i open the browser but no internet connection
pinging the gateway returns "Destination Host Unreachable"

i thought that may be someone using any kind of arp attack "spoofing"

but that what i found

root[ahmed]# arp -n
Address                  HWtype  HWaddress           Flags Mask            Iface
10.100.2.177                     (incomplete)                              wlan0

10.100.2.177 is the gateway address but why it didnot see the mac address

i used arp -s to add a static entery for the gateway and ping the gateway again

root[ahmed]# arp -s 10.100.2.177 00:60:43:00:3b:66
root[ahmed]# arp -n
Address                  HWtype  HWaddress           Flags Mask            Iface

root[ahmed]# ping 10.100.2.177
PING 10.100.2.177 (10.100.2.177) 56(84) bytes of data.
^C
--- 10.100.2.177 ping statistics ---
11 packets transmitted, 0 received, 100% packet loss, time 10048ms

notice the red line .why this packet loss ?????????????????

and yes no firewall working

root[ahmed]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

now if i disconnect the cable from the access point and connect it to my ethernet lan every thing goes fine

root[ahmed]# arp -n
