Okay, you are associated.  So nothing is wrong with your wireless.

   root at pachy:~# ifconfig -a
   eth1      Link encap:Ethernet  HWaddr 00:60:1D:F7:76:9D
              inet addr:192.168.55.5  Bcast:192.168.55.255  Mask:255.255.255.0

              RX packets:0 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
              Interrupt:3 Base address:0x180

and you've got an IP address for it.  Is this "static" or "dhcp"?

   root at pachy:~# route -n
   Kernel IP routing table
   Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
   192.168.55.0    0.0.0.0         255.255.255.0   U     0      0        0 eth1
   169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth1

Is 192.168.55.4 really your gateway?

   root at pachy:~# ping -n -c 1 4.2.2.2
   PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data.
   >From 192.168.55.5 icmp_seq=1 Destination Host Unreachable

because this implies it isn't.  Try pinging the gateway:

 $ ping 192.168.55.4
