Re: [Iperf-users] sender reachs 54M to send packets when link disconnect (802.11g)

[Marc H. <mar...@gm...>]

Hi,

   What seems to happen is that your sending operating system is 
dropping all the packets internally. Since UDP is not reliable your 
operating system is perfectly allowed to do that.

How would you like your operating system to behave instead?

Cheers,

Marc
