TTL definition for wireless LAN

[nelljack]

I'd like to know what this line below means:

Ping (a number): bytes=32 time=xxms TTL=255

I know it is to ping the ISP address, etc, but what does it mean when the TTL number goes from 255 to 250, then to 249...?
I was told this ping number should always be at 255.

Thanks.

Thanks Kaisali, but the info link did not answer my question. Why would the TTL number keep decreasing and what does it mean when it does?

TTL stands for "time to live" it is the number of hops a packet can take through a router before it is considered lost.

In your case it means the packet can take 255 hops through a router before it is discarded. Each time the packet goes through a router the TTL decreases by 1
