Packet Loss

[Andrew Hodel]

Using iptables and setting -->

TCPMSS     tcp  --  anywhere             anywhere           tcp
flags:SYN,RST/SYN TCPMSS set 1000

on INPUT, FORWARD, and OUTPUT helps a little, however I am still
having connection reset problems.  A tcpdump only show
retransmissions, nothing out of the ordinary for wlan.

any ideas?
