OpenWRT and DDWRT wont give you Higher Speed.
These 2 enhanced FW for Routers will only give you
WiFi Freedom and Stability, hence a speedtest showing Highspeed does not necessary Guarantee High Speed for everyone. Chuah's case is different cause he live in an area that can
Max out on his QoS of 16000/8640 due to several reasons, namely
1) His proximity to a
FEW MAXIS TOWERS there
2) The density of users there, maybe those pipu there dun use M3G internet, hence he sapu all the Bandwidth.
3) The height of his Unit in his Apartment
4) Clear line of sight of the Towers.
5) I believe the area around Maxis Flagship Building, KLCC area have excellent signal but users there complained they dun get good speed even the QoS is 42000/8640 , Why ? simple, Users Density so is HIGH, everyone is fighting for Bandwidth, hench they got sucky speed.
If you guys wan Stronger WiFi and Better Stability on your connection, try the 2 routers trick which i mooted. Even Chuah is using it now. Like one of you guys mentioned before, using 2 Routers is like running a Dual Core processor compared to a Single Router. It does helps on the power distribution of the routers. One router to do the job of dialing of the modem and connection and another router to do the channeling of the signal for usage, LAN or WiFi.
I believe a third factor which might help to get the best out of the setup, that is to utilise Gigabit LAN ports or Switches.
Best combo is Router A( Gigabit LAN port present) dial in > Router B ( also Gigabit LAN port present ) > LAN out to Gigabit Switch ~ mutiple pcs /WiFi out . The dial in router should be OpenWRT and router B should be DDWRT.
It was said that DDWRT have issues with dial into 3G USB modems, so we have to use a OpenWRT router to do the dial job. DDWRT have better management, so we will use it to manage the second router.
Chuah, the ball is at your feet now. Prove to us that you a C7 or Messi now.

oh i forget to mention that result is using v1 alone with new openwrt plus wifi out :Dfrom last night till now still using v1 alone to dial 3g modem + wifi out. No issue at all. Single routers working great so far
