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.
