Increase Data Speed [Wifi/3G/4G]
This is a known linux tweak and I have tested it on the epic and there seems to be mixed results. BTW,YMMV so don't go blaming me for messing up your phone...
Open up /system/etc/sysctl.conf (make it if it isn't there)
Add the following...
==================
net.ipv4.tcp_ecn=0
net.ipv4.route.flush = 1
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_rmem = 4096 39000 187000
net.ipv4.tcp_wmem = 4096 39000 187000
net.ipv4.tcp_mem = 187000 187000 187000
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
============================
