TCP Congestion Control – Vegas and DD-WRT

If you have flashed your router with DD-WRT and have the latest versions, you may have congestion control as an input or selection.

If you want equal time for all of the applications you are running such as VoIP or gaming, Vegas may be the way to go.   Although it is a selection, you can process it upon the start-up of your router by inserting it into the command box under Administration.

Normally most users have selected Vegas (below).

Vegas performs better on the internet and can achieve higher than 70% better performance.

The necessary modules for TCP Vegas are included in DD-WRT distributions.  You can enter the follow commands into your router to enable vegas. The router should dynamically allocate throughput.

Go to Administration and Commands – Enter the following:

echo 0 > /proc/sys/net/ipv4/tcp_westwood
echo 1 > /proc/sys/net/ipv4/tcp_vegas_cong_avoid
echo 3 > /proc/sys/net/ipv4/tcp_vegas_alpha
echo 3 > /proc/sys/net/ipv4/tcp_vegas_beta

Now save to Firewall.
