Powerbook Lombard Wireless Stability


I now have updated my Lombard to 512 MB ram and a 40 GB hard drive. I installed OS 10.3.9. I have a D-Link USB wireless adapter and it was solid as a rock with the previous 10.3.9 system on the old hard drive. Now each time I boot up I have to reenter the DCHP parameters, first manually and then switch to DCHP and it connects ok. This happens after I "lock" the preference pane. After rebooting it is "unlocked" and I have to go through the above procedure again. Does this sound like a D-Link software problem? I have run Disk Utility to repair permissions.
