Comment 10 for bug 79296

Hi,
Finally got it working.

I had the same problem, upgrading from 6.10 to 7.04 on a Fujitsu-siemens amilo-A cy26, all worked except the MSI CB54G2 PCMCIA WiFi.
(btw, thanks for enabling the dsdt-from-ramdisk in the stock kernel, now i don't have to recompile to get the 3D working)

changed auto lo ot auto ra0 in '/etc/network/interfaces'
 # The loopback network interface
 #auto lo
 iface lo inet loopback
 # The primary network interface
 iface eth0 inet dhcp
 auto ra0
 iface ra0 inet dhcp
 wireless-essid *******
 wireless-key s:**************

Didn't work... :( regardless of several ifup/downs
Fiddled a bit with my wlan-modem, made the ssid non-hidden and changed channels, suddenly: success!
Changed the ssid back to hidden, modem is now running on channel 3.
Seems rock solid.
