Resources:  Original Discussion Thread, NS1 File Reference, Required File Download

Assumptions:  This page assumes you know how to download and extract a file to your own system.  If you don't know how to do that, you probably shouldn't be attempting this procedure.

• Step 1:  Download and extract the File from the "Required file Download" link Above.

• Step 2:  Run XVi32.exe from the extracted directory.

• Step 3:  Make a backup copy of all your NS1 files you will be attempting to repair, in case something goes horribly wrong.

• Step 4:  Open the corrupt NS1 file in Xvi32.

• Step 5:  Reset the AP count in the File header to 00 00 00 00 (do not use the Delete or Backspace key at any time inside this file, it will delete the byte from the file)

• Step 6:  Try to open the file in Netstumbler

• If the file opens proceed to Step 7
• If the file fails to open the file is probably corrupt beyond Repair.
• Step 7:  Set the AP count to the approximate number of AP's before the file crashed.
• If the file opens, increase the AP count by 20 and open until the file fails to open in Netstumbler, proceed to Step 8.
• If the file fails to open, decrease the AP count by 20 until the file opens in Netstumbler, proceed to Step 8.
• Step 8:  Increase or Decrease the AP count by 1 until the file fails to open then back off the AP count by 1.
• Step 9:  You have Recovered all AP's that can be recovered. Any AP's past the value entered into the header are corrupted beyond recovery.
