Next, find the connection labelled WiFi in the following menu, right click this entry and choose “Status” On the menu that pops up next, click on the “Wireless Properties” button. From here, you will see another window pop up, move to “Security” tab in the window, then tick the box next to “Show Characters” and your password will be visible. For computers running Windows 7 and connected to a wireless network, follow these steps to find the password: Click the wireless strength indicator in the notification area on the taskbar (lower-right corner). Right-click your wireless network name, and then select Properties. I have had my MacBook Pro for a couple of months (recent Windows convert and total Mac novice). I am running OS X 10.8.4. Our cable company recently upgraded our modem and cable box and I am no longer able to connect to the Internet over Wi-Fi. ![]() I can connect via Ethernet. Also, two windows laptops, two iPhones and an iPad are all connected via Wi-Fi so I believe the wireless signal is working and can be connected to. I can see the network but when I enter the password the login box shakes like an incorrect password was entered. This is the same password I use for the other devices and I have carefully entered it many times so it should work. I would appreciate any thoughts you might have. Thanks, Jason. I would recommend removing the wireless network from your preferred networks. You can do this by going to your network preferences. As follows: Open Network Preferences > Select your Wi-Fi connection > Advanced. Select the network from the list on the first Wi-Fi Tab and hit the [-] key then click OK. Once you have done this, click Apply on the next screen. ![]() Next you want to remove the password from your keychain to make sure its gone. So open up Keychain Access Application. Search for the wireless network name. Select the network name and hit delete key. Click the delete prompt to be sure. Close Keychain access and retry connecting to the wireless. This should have removed all traces of the wireless network from your computer and allow you to try it again. @Lyken, thank you for the detailed answer. When I went to complete those steps I found that my network was not saved in my preferred networks. Not knowing what else to try, I accessed my routers configuration settings and examined my options there. I attempted to change the security to WEP but was unsuccessful (not sure why). However, upon exiting the configuration I was then able to connect via Wi-Fi. Unfortunately, I am not smart enough to deduce why it now works so I can't add much to the conversation. Thanks again for your help. – Aug 28 '13 at 10:48 •. I had the same problem. I kept entering the WPA2 password CORRECTLY, and it was rejected each time. I went into Settings as above to change, and noticed that everything was grayed out. I then remembered that the account I'm usually logged into is not an administrator's account (for security reasons). So I had to go back to the main Network pref pane, click the lock icon, and give my administrator login name and password. Without doing anything else, I was now able to access the wifi network again and it took my password without any difficulty. I'm not sure if this will work with you, but my brother has the same issue. He uses a MacBook Pro 2010, while I have a MacBook Pro 2011. I can connect to my Wifi, yet he can't. Invalid password always comes up. After trying some ways, I found that I need to turn ON QoS setting on my Wi-Fi. And set it to WMM () (if not available, I think just turn it ON). This setting is located on your Wi-Fi-router admin page, network tab, wireless section (Wi-Fi admin page usually just type on your browser 192.168.1.1 from connected device, with 'admin' username and password). Now both of us can connect. Just fixed this problem for myself. One computer would not connect, even with the correct password. It would connect to a MiFi card, however. And every other device could connect to the router. So, they were both working, but not with each other. Both the computer and router support 2.4 GHz and 5 GHz. But it turns out the 5 GHz transmitter on the computer failed, but was still trying to connect at 5 GHz.
