I'm new to everything but I got bored today so I decided to put a heatsink on my wrt54gl. I can't get it running @ 250mhz stable and I had an extra socket 775 heatsink left over so I decided to give it a shot. Now I want to do 275mhz =D

Post pictures of your modded routers please! =D

This heatsink is the Arctic Cooling Freezer 7 Pro.

Cool.. (no pun intended Razz ) A wee bit overkill but nice job..

How did you attach it? What's holding it in place?

I have a few heat sinks in mine. I've got the radio, cpu and ram covered. I also cut a hole and put a 80mm fan on top. Though my heatsinks fit inside the stock case. I also have a 3 amp 12v power brick. I can get my WRT54Gv4 to 288 mhz with hacked CFE. Though I only run it at 275 mhz. I'm looking for a way to over volt the cpu a bit to increase the overclocking.

First of all try to find stable and lite firmware version. On my WRT54GL o/c with Tomato 1.27 is max stable @ 216MHz, but with Tomato_RAF_1.25.8515.2-ND from http://victek.is-a-geek.com/tomato.html works flawless @ 275MHz, and WiFi carries approx 3.0 MB/s. WAN to LAN throughput 4-4,5MB/s, but i guess this is the maximum for my tariff plan (it's shared, not guaranteed)

Only passive heatsinks on CPU, RAM, WiFi chip.

All I did was rip an AGPset thin-looking heatsink from an old mobo, use the thermal glue that was already with it, stick it on the broadcom chip. And then dremmel the top out and mount an 80mm fan connected to an old PSU.

225MHz no problem, will try 250MHz later.

A heatsink in OP is foolishly overkill.

Love that picture...haha

What are the performance gains from over clocking the CPU's? I only have been working with WRT54G (2)(L)'s

Some are routers, access points, and repeater/bridges. I have a number of smaller heatsinks (hahah.....still laughing at that pic) and wonder if it's worth messing with.

I took a Heatsink & Fan off an old Video Card that I had in a box, machined out a section so as to not interfere with the crystal next to the processor.

I also changed out the power connector so that I could install a socket for the power wire.

This photo is before I did the SD/MicroSD card mod.

DD-WRT firmware allows you all kinds of options that the stock Linksys firmware doesn't. Anywhere from overclocking to wireless transmit mW tweaking, to your normal WPA2 security stuff. My purpose was to boost the Xmit power setting as far as I could, safely. The default setting is 28, the problem is, the DD-WRT manual specifically states, any Xmit power increase above 70 can cause the router to overheat and fail before its time. I wanted more than 70, more than 125 even, just for testing purposes to see what the gains really could be.
