I use a public wifi. (connect with id/password on an open network)
The network is unstable (download stream 500ko/s then drop 0ko/s and stream stop, if a click a later in the stream it's working again) With this wifi, if you use MAC spoofing you basically don't have to pay for id/password so I suspect that. (plus a lot of scan ARP request from .0 to .255 in wireshark : strange)
On my interface i have a lot of TCP Dup ACK and TCP Retransmission, and sometimes RST (i think RST is when the stream stop).
Is there a way to deal with this ?
