This line: 

Rx invalid nwid:0 Rx Invalid crypt:0 RX invalid frag:0

does not necessary mean that wlan connection is not working properly.

does #ip addr

show an ip address for wlan, inet?

If so, what is the ping response to the router from the Vaio?
One of the things I sometimes miss is DNS configuration,
check /etc/resolv.conf. 

To search for wireless networks, try #iwlist wlan0 scanning|grep ESSID

Hope this gets you part way there...
