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
The wifi adapter we are using here is wifly-city 54G the TX power of it should go as high as 30 dBm
in windows 7 it’s working in automated for the TX power and it’s not going higher than 10dbm and sometimes even it’s down to 1dbm but the good thing is it’s working fine without disconnecting.
on Kali Linux, The TX power is set to 20dbm but after a few minutes in Kali Linux, I got disconnected for no reason… will that what I was thinking its just bad drives for my adapter, but when I try to change the TX power in Windows 7 and I did change it from 10dBm to 30dBm the adapter stooped working after few seconds so I change the TX power to 20 and yet the same thing it’s not connecting anymore…
here i remember Kali Linux and yes it’s the same thing here and there so the TX power is behind all of this..
i wanted to check my wifi adapter chips is it hot ? i could not keep my finger on it it’s way too hot
so here I start thinking how to fix the heating issue and here is what I did to cool down my wifi adapter, now I will leave you with the photos 🙂 so here is the wifi adapter
Open your WiFi adapter case and look for the chips, here is a photo of The chips
as you can see it’s RTL8181L chips and it’s perfect for monitor mode
- it’s the chips
- it’s a mark I made to know where I should cut the case
I make a line because this is all what i need but you may need to cut more than just a line it’s about the hear sink you are going to install,
now after we got everything ready and as you see I cut the case and I put the Aluminum Heatsinks
the Heat sink of such proportions can be found in many electronic devices or may cut a big Heatsink, or you can just buy it… the one I’m using here wasn’t meant to be a Heatsinks but it does the job perfectly
So you have to place the heat sink over the Chips but before placing the heat sink you need to put heat sink tape and that can be found on computer shops or get it from amazon, but I didn’t have a heat sink tape so I used a Gum! yes, a Gum, it must be without sugar… the one is used is Trident
you can see how I place the gum over the chip and there where you should do but if you were using a heatsink tape then you should place it all over the chip then you place the heat sink over the gum or over the heatsink tape
With those steps, your adapter is ready to be used with high TX power without any heating problems, you can add a fan to the heatsink if you like for extra cooling.
even if you don’t face such a problem you can do it just for the fan of it !
what i you will need for this protect is:
