Stealth Mode networking ?

when i ping my machine i still get a response

Then it is working as designed.

stealth mode only hides the wi-fi network name, and makes the user specify it instead. It turns out there are also other ways to observe the network name anyway.

many Admins consider it useless at protecting your network.

stealth mode requires firewall turned on.

You're probably running a server here, based on the forum where this is posted. Servers have open network ports, or they're not much good as servers. Blocking ICMP traffic — "stealth" — makes networking problems harder to debug, and it's far from certain that "stealth" will do what you intend here as a host can generally be spotted through some other open port and active service, and variously also spotted via routing-level traffic. The botnets try anything — ICMP, sniffing open ports via syn scans, brute-force port access attempts, whatever. ICMP traffic is also used by web content caching and content delivery network providers, to establish locality.
