Macbook Pro WiFi doesn't work!

[allfor5]

I have a 2011 Macbook Pro 15" A1286 and the wifi doesn't work. I think I need to replace the wireless card. I tried SMC and PRAM reset and nothing happened

Can you guys tell me what kind of card I need and post a link? Because I Saw two different types on ebay.

Also, are all 15" MBP called A1286 and all 13" called A1278? Thx .

Check if you have a wifi configuration by going to System Preferences>Network. On the left side, you should see a wifi configuration. If there is none, Add one by clicking "+" on the bottom left. Select wifi and youre set.

If that did't work, I suggest you to bring it into a genius bar. It will most likely cost money so its easier to buy a wifi card.
