I have a couple of years old router which has been serving effectively since then. Recently, I expanded my home network to serve multiple access points and poe endpoints, which has created an over head on this old guy.

Users on the network experienced multiple connection lose repeatedly. This is affecting productivity of the users since then including myself, which lead me to take a step in regards fixing this device.

In this instruct-able, you'll find some common techniques/DIY to fix electronic devices problems which is caused by heat.

I would like to mention the problem with my router is not completely fixed, but I can feel a big difference on the before/after experience! :)

Step 1: Fixing Dead Component

Heat cause damage to devices, and when talking about electronic devices, we should mention the effect of heat on electrolytic capacitors.

These components are rated by the manufacture with max temperature, if exceeded, permanent damage to the component will occur.

You can detect such component by the change of its color, or in case of electrolytic capacitors, a bulge will be visible to naked eye.

With basic soldering skills, you'll be able to replace the component with a new one. Multiple tutorials around the web are available to guide in this manner.

Step 2: Air Circulation and Heat Sinking

In my specific device, the absence of air circulation was the cause of the issue. Since I was using the device as a router only, and leaving the switching part to a dedicated switch (connected to multiple IOT devices and lots of APs), The router is locked in a closed cabin, which cause excessive heat, that caused multiple lags and disconnection of internet.
