wifi card for asus

Hi Framan Ali,

Replacing the WiFi card on your laptop is relatively easy. Unfortunately there isn't a guide specifically for that here on iFixit, but all of the instructions you need are available within the motherboard replacement guide.

Obviously you don't need to remove the entire motherboard to accomplish this; as a matter of fact you can skip most of the steps. Just follow the steps listed below in order and you won't have any problems.

Step 1 Back Case
Step 2
Step 3
Step 5
Step 10 Motherboard

Final step is to just remove the screw circled in red below.

Lift the WiFi board slightly on the edge opposite the connector then slide it straight out to remove it.

Now that you know how to do it, I'm afraid the question of what you can replace it with still remains. Unfortunately I don't have an answer to that; hopefully more knowledgeable users on this site can help.
