Hi list! Simple(?) question: How do I enable "tcp fast retransmissions"?
I've got a wireless network with a lot of interference which results in about 30% packet loss. Fast retransmission should help here, right? However: * Counter for fast retrans in 'netstat -s' is always zero. * Nothing appropriate in 'sysctl -a' Is TCP_FACK (commented out in conf/GENERIC) what I'm looking for? But I've got the suspicion that TCP_FACK is outdated (dead?) code: * TCP_FACK was reenabled in plus26.html but this is obviously outdated and not accurate anymore. * Google lists references to TCP_FACK in 3.2,3.3 and 3.4 FAQs but nothing in recent FAQs. Are there any other network settings to tweak for networks with high packet loss? Regards, Walter
