fi

sleep 45

done

for save file in vi type :wq

:wq

change script to executable

chmod a+x /usr/bin/truecond

because original wget from Openwrt didn't support https so we have to get GNU wget

opkg update

before use this command make sure your router can connect to internet
and your have to authentication manually through trueinternet redirect site for the first time

http://192.168.1.1

scan and connect to true wifi
now change to @TRUEWIFI






















login to router again

ssh root@192.168.1.1

test internet access

ping google.com

























okay when router can access to internet
let update package list again

opkg update













get ez-ipupdate for dyndns update

opkg install ez-ipupdate

get ntp-update for time correct

opkg install ntpdate

now get GNU wget

wget http://downloads.openwrt.org/kamikaze/8.09/brcm-2.4/packages/wget_1.11.4-1_mipsel.ipk

and install it , we have to force install because it alredy exist form busy-box build in

opkg -force-overwrite install wget_1.11.4-1_mipsel.ipk

now you will get GNU wget















now we prepare all thing done
next is make is run as startup when start router

vi /etc/init.d/truenet

#!/bin/sh /etc/rc.common

START=99

start() {
/usr/bin/truecond > /dev/null 2>&1 &
}

stop() {
killall -9 truecond
killall -9 sleep
}

for save file in vi type :wq
:wq

chmod a+x /etc/init.d/truenet

now make is run as init (start up)

ln -s /etc/init.d/truenet /etc/rc.d/S99truenet


reboot


after reboot try browsing internet from your computer(after wait 5 minute) because we sleep 300 second

when timeout(in this case 80 minute) and your are browsing webpage found redirect to truewifi authentication page don't have to enter username and password
just wait for 45 second and router will connect it self

Have some fun.
