You could try to specify the access point in /etc/network/interfaces:

# The primary network interface
auto eth0
iface eth0 inet dhcp
wireless_essid <your_access_point>

Before modifying /etc/network/interfaces, do "sudo ifdown eth0" to
bring eth0 down. And after modifying /etc/network/interfaces, do "sudo
ifup eth0" to bring eth0 back up.

Hope this helps,
