I used computer's fan to cool the wireless, attach the fan to the wireless and will use the same power source of the wireless (wireless NO fan ON, wireless OFF fan OFF)
Maybe you will ask me why should I cool my wireless network router?
The answer is: by cooling your router you are avoiding slowing down (especially while downloading big files) because if you are using the router too much (such as downloading big files. you can notice that by seeing the LED's in the router) it will get hot, and you know that Electronic devices will not be efficient if it's not working in the right temperature.
Also because I live in a hot country and I am noticing that the heat is affecting the wireless.
Step 1: Things You Will Need
1. Fan (I used Desktop PC's fan).
2. Male jack that is similar to your wireless jack(I found it in an old adapter).
3. Female jack that is similar to your wireless jack.
4. Some glue.
5. you will need to solder some wires.
Step 2: Connecting Wires
Connect the red wire in the fan to the center pin in the female jack (+) and the black wire to the other pin (-)
now you should connect the male jack with the fan in parallel (as shown in the pic)
In my case the male jack has two wires inside each other. The (+) wire is in the middle (inner wire) and the (-) wire (outer wire) is surrounding the (+) wire. Separate the two wires and connect them to the right pin
And don't forget to insulate them so it won't be short circuited (I used gun glue)
Step 3: Gluing
now connect router's male jack to our female jack, the fan will start and you should notice which side of the fan is sucking and which side is blowing.
Glue the blowing side to the wireless (glue it in a side that has many hols)
IT'S TIME TO TEST IT
