I have the same driver and utility installed on my old powerbook which has Belkin WiFi PC card, I bought it as a replacement for one that broken by my son.

Belkin previously used Broadcom chips which are supported by Airport software, but switched to Realtek without changing the model number.

That forum thread and knowledge base article aren't connected to this issue at all, except that both involve ARDAgent.

The claim "Apple's built-in file system permissions verifier really wanted to delete the ARDAgent program" is just nonsense.
