    Just a little FYI:
    I Upgraded to the latest firmware located on the support.dlink.com site, It 
    seems as though this is vulnerable as well and returns:
    
    Type          : GL2422AP-00-0M0 T1.0 -042.3
    Announced Name: DWL-900AP+
    Admin Username: admin
    Admin Password: admin
    SSID          : default
    Wep Key       : 00 00 00 00 00 00 00 00 00 00 00 00 00
    
    (The Wep Key, Admin password, and SSID have been changed to protect the 
    innocent)
    
    Again, this is the latest firmware located on the dlink support site:
    Firmware Version 2.3 , Tue, 29 Sep 2002
    Which was apparently relased on the 4th November 2002, as per the information 
    on their site. The site clearly explains though that it is only an upgrade to 
    secure TFTP and nothing else though.
    
    The informaion was extracted using the "Altered Test Prog" (and a bit of 
    tweeking) that /håkan supplied in previous posts. Correct me if I'm wrong, and 
    being quite new to the security scene, I imagine I would be, but wouldnt the 
    most logical step for firewalling, to update a ruleset that doesnt allow 
    network wide broadcasts, if it can be helped that is?
    
    If anyone needs me to run some more tests, just let me know what to run.
    
    Cheers
