So the question is How to cool down my wifi card in this post I will show you how to cool down your adapter

first why would you increase wifi tx power? it will Increase Signal Strength and that mean a better connection and more access point will show up.

but you may get your adapter damaged from heat, a high TX power case so much heat, the higher your tx power is the hotter the adapter will get, so if we play with the TX power of the adapter we may face a new problem and it’s the heat of that adapter and that what happened to me! if you don’t know how to increase wifi adapter power please check this
