Do NOT buy antenna on ebay!
I have personally purchased a pair of "9dB Antenna" from a VERY reputable seller. They did not reach anywhere near 9dB. If you follow this instructable and use antenna you got from ebay, don't complain when it doesnt work.
Step 1: LEGAL
Step 2: Do Not Run With Scissors
In this project we will be working with solder and flux fumes, both of which can cause cancer, so let’s not take any chances and wear a respirator that filters those fumes, or make yourself a good fume extractor with carbon filter.
Lastly, put your favorite beanie on. If you get frustrated, your brains are likely to leak out your ear, and let’s face it, you’re just going to leave it for someone else to clean up.
Step 3: Gather the Supplies
Extras that I recommend:
Step 4: Dissect the Specimen
Step 5: Add Power Cable
Step 6: Aquire Heatsink
Clean with a lint-free cloth and rubbing alcohol over and over until no more residue rubs off and discolors the cloth.
Then clean it again.
Maybe once more.
Grab your vice grips, clamp them on to the bracket nice and tight, and bend it back and forth till it snaps off.
Now by default, the fan blows air AT the heatsink.
For this mod, we want the fan to blow heat up and out of the unit and away from the CPU.
I have only had it happen once, but the sticker came off and got jammed between the fan and heatsink, blocking the rotation. The router was not damaged, but the fan had to be replaced.
A dab of superglue might work if the adhesive doesn’t.
I recommend using a cone shaped routing bit, but others can be used so long as you’re very cautious.
The cone shape helps keep you from drilling the holes TOO BIG all the way through, thus preventing you from accidentally making holes that the screws just falls through.
Step 7: Install Heatsink
Step 8: Mount the External Fan
Step 9: Wire It Up
The pictures for this section can sum it up much better than I can, so I’m going to leave it at that.
If you aren’t sure which large speaker wire to attach your little ones to, just plug it in, touch the wires together, and if it works, mark those wires. If it doesn’t, Mark the other wire.
I solder all the wire connections together, just follow the same steps as step 4 for wire soldering.
