You do not say what kind of internet connection you have, but 2 potential
causes are ECN (which I think is disabled by making sure that
/proc/sys/net/ipv4/tcp_ecn, if it exists, contains zero), or an mtu
discovery problem (if using pppoe).
pppoe uses an 8 byte header, so to fit within 1500 byte ethernet, pppoe
has max mtu of 1492, but in some cases it is less. If there is an mtu
discovery problem, you may need to set mtu of LAN ethernet devices to 1492
or less (but not the nic that carries pppoe itself).
