OpenWrt Network Tweaking by adding Hybla Max Congestion controller and tweakings

XMAN · Jul 15, 2021

OPENWRT

Download OPENWRT SDK according to your router architecture

cd sdk
Click to expand...

Upload "hybla_max" folder to package folder

make menuconfig
Click to expand...

Select Kernel modules --> Network Support ---> kmod-hybla_max

make package/hybla_max/compile V=99
Click to expand...

Navigate to bin directory, find and install kmod-hybla_max.ipk

insmod tcp_hybla_max.ko
echo "tcp_hybla_max" > /etc/modules.d/hybla_max
sysctl -w net.ipv4.tcp_congestion_control=hybla_max
Click to expand...

Linux

Download "tcp_hybla_max/module" folder

cd tcp_hybla_max/module/
make
insmod tcp_hybla_max.ko
sysctl -w net.ipv4.tcp_congestion_control=hybla_max
Click to expand...

You can load module on startup in rc.local file

Route Tweaking with ip route

Tweak your lan network and at first check your network routes because it differs from network to network. ex: 192.168.1.0/24

ip route
Click to expand...

[root@THROTTLEFIX.COM_OpenWrT:/root]#ip route
default via 172.23.0.250 dev eth0.2 proto static src 172.23.0.249
172.23.0.0/16 dev eth0.2 proto kernel scope link src 172.23.0.249
172.23.0.250 dev eth0.2 proto static scope link src 172.23.0.249
192.168.1.0/24 dev br-lan proto kernel scope link src 192.168.1.1
[root@THROTTLEFIX.COM_OpenWrT:/root]#
Click to expand...

Create .sh script in order not to get disconnect because we need to delete route and re-add a new one

vi run.sh
Click to expand...

add the following :

ip route del 192.168.1.0/24 dev br-lan proto kernel scope link src 192.168.1.1
ip route add 192.168.1.0/24 dev br-lan ttl-propagate enabled proto dhcp scope global window 999999999 rtt 4000000000ms rttvar 0ms cwnd 1 initcwnd 1000 nexthop dev br-lan weight 1 realm 2
Click to expand...

sh run.sh
Click to expand...

Note: ttl-propagate option is not available on old iproute, please make sure you are running on latest kernel
