Comment 21 for bug 207446

All in all I have come to the final conclusion how I made it work for me:

1) install Will's patched drivers

2) adding ieee80211_crypt_ccmp-rtl to the /etc/modules

3) configure interfaces and wpa_supplicant.conf as above

Then it loads fine on boot and works fine with hidden SSID. I have added ap_scan=2 and scan_ssid=1 as below to the wpa_supplicant file, but have not tested if this determines it works with hidden SSID (my guess would be it does not but since it does not hurt..)

ap_scan=2

network={
    ssid="*********"
    scan_ssid=1
    proto=WPA2
     #proto=RSN <-- one setting proto=wpa2 does the job
    key_mgmt=WPA-PSK
    #pairwise=CCMP <-- one setting proto=wpa2 does the job
    #group=CCMP <-- one setting proto=wpa2 does the job
    psk=***************************************
