How to overclock a WRT54GS v4? & another Q

    First off wonderful posts and documentation in this forum. I recently switched over to Tomato 1.28 for the wireless ethernet bridge feature with a WRT54GS v4.

    I had initial connection issues but learned that this mode only supports the security settings of WPA-Personal w/TKIP. Can anyone confirm this? So far it has been the only way I can connect to the main router. I then increased the Transmit power to the recommended 150mw.

    Right now I average a signal quality of -60 to -70 RSSI with a noise rating of -94. I will be dumping my D-Link DGL 4500 soon for a WRT54GL soon.

    What I want to know is how to issue commands to the router to increase the CPU speed. Nobody has really explained it, beyond giving the commands to input via Terminal. But have no idea how to properly access my ethernet bridge in such a way. Also do I even need to overclock with my current connection?

    Some help would be much appreciated.

    hello Gunharp

    connect to your command shell (wrt54) and enter these commands

    should be stable
    206, 216, 217, 225, 238 and 250

    check/show commando:
    please note that you need a passiv or active cooling system e.g. here . for more information about OC look here and

    Umm, no, you don't need added cooling. Those frequencies are stable because they're the chips frequencies. Adding fans just increases dust and it's the smallest dusts particles that conduct electricity hence short electronics.

    Shoving a passive heatsink on is both cheap and pointless also, although it won't do any harm.

    @switchit @Azuse

    Thanks so much : )

    I was successful in using PuTTY to apply a modest overlcock of "225".

    Just procured 3 WRT54G routers today. I set up one as my access point with w/150mw transmit power.

    Are there any good tutorials about how to get the most out my new Wireless G network? (outside of the hefty QoS tutorials). Enabling WMM seems like a good idea but I have no idea really.


    Well managed to brick one currently has a constant power led... yikes. Any reason why applying the overclock on a WRT54G v2 would brick it on reboot? I think it might because I gave it a speed outside of its range (225).

    Possibly, never touches a v2 myself. Oh and I believe 84mw is the transmit limit before you begin to damage the chip.
