I get 'Destination host unreachable'

No, I get the message 'can't establish connection to the server at  
xxx.xxx.xxx.xxx

That seems to be ok and pointing to the wireless network interface:

Destination  Gateway        Genmask  Flags  Metric  Ref  Use  Iface
0.0.0.0      <router's ip>  0.0.0.0  UG     0       0    0    wlan0

No, the router is ok. I can use the wireless AP from another laptop  
and I'm not using any kind of mac address filtering. The laptop does  
get access to the same router when using a cable to connect it to the  
AP's switch ports.
