Well, this thing keeps happening in this MacBook Pro. After installing the system updates, randomly the Wireless stops working. So, doesn't matter how many times you try to connect to the WPA wireless that it won't just connect. Doesn't matter either how you do it, which panel you go from or which option you click. I'm talking about MacOSX by the way.
So, the solution for me was interesting...
1) Go to your wireless router, get rid of the WPA, leave it without protection for some minutes.
2) Connect with your computer to the unprotected wireless. You're allowed to scream "yeeey!" if it connects.
3) Then go back to the router config, set back the WPA password, and connect again. Again, you're allowed to scream "fuck yeah!!" if it works |
