Every time I want to connect my computer to my network, I get asked "The Wifi network requires a WPA2 password."
I have an Airport and Airport Express base station. So, I enter the password and check the "remember this network" box. Yet, I get asked for a password every time. Annoying after a while. How do I fix this?
Thanks

This is not an AirPort router problem....this is a problem with your Mac's operating system, so you may have better results posting in the Sierra support forum.
The first troubleshooting step to perform.....if you have not already done this.....would be to clean out the history of networks that your Mac has joined in the past, so you can start from a clean slate. To do that....
Open System Preferences (gear icon on the dock)
Open Network
Click on WiFi on the left panel to highlight it
Click the Advanced button at the lower right of the window
Here you will see a listing of all of the networks that the Mac has joined in the past.
Click on the name of a network to highlight it
Click the - (minus) button at the bottom of the list to remove the network listing.
Do the same for all other networks that appear until the list is blank.
Make sure that a check mark in entered in the box that reads "Remember networks this computer has joined".
Click OK
Click Apply in the next window.....(this is an easy step to miss)
Close the windows
Restart your Mac
Connect to the wireless network again from your Mac. You will be asked for the password, but if things are not corrupted in the KeyChain settings, your Mac will remember the password in the future.
If still no luck, the settings for the network in your KeyChain are likely corrupted. Rather than look for an obscure setting and try to make changes....which can be dangerous.....my recommendation would be to rename the wireless network and password on your AirPort routers and try things with those new settings.
If the Mac still cannot remember the network and other devices can.....you will likely need to reinstall the Sierra operating system on the Mac. As mentioned previously, you have a Mac / Sierra issue, so you will likely get a faster and more informed answer if you post in the Sierra support forum which is linked just below. Good luck.
I don't see why Sierra would be the issue since the same problem was there with the previous OS.
The point that I was trying to make was simply that your problem is the result of an operating system issue.......not an AirPort router issue. It is a Sierra issue because that is the operating system that is currently installed on your Mac. If you were running El Capitan, it would be an El Capitan issue.
That being the case, it might make sense for you to consider posting a question about an operating system issue in the support forum for the Sierra operating system.....where the Sierra gurus hang out.
It might take 5 minutes for you to test and see if the Mac will connect and remember the name of another network using another password. You never know, it might work and ultimately save you hours of additional troubleshooting. Worst case, you lose 5 minutes.
Hopefully, Tesserax will have more ideas. Good luck.
In addition to Bob Timmons' comments:
Try the following on your Mac in order, until (hopefully) resolved:
Create a New User Account
Click "+" to add a new account.
Log off, and then, log back on with the new user account.
Try connecting to a Wi-Fi network with your Mac's AirPort.
If this resolves the problem, there may be something amiss with your current profile and will require further troubleshooting.
If this does not resolve the problem, go ahead and log back into your normal account and go on to the next step.
Launch the "Keychain Access" application located in Applications/Utilities.
In the windows on the left side: Select login for Keychains and "Passwords" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
Close Keychain Access.
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Delete all entries under "Preferred Networks."
Click on OK.
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Click on OK.
Restart or log out, and then, back in.
Quit any applications that are currently using Wi-Fi.
Turn off Wi-Fi from the Wi-Fi icon on the macOS / OS X menu bar.
Open Finder > Go > Go To Folder > Enter "/Library/Preferences/SystemConfiguration/" into the Go to the folder window > Click on Go
Locate and select the following files:
Note: Files are macOS / OS X version specific, not all the following files are used in each version.
preferences.plist
Reboot the Mac.
Re-enable Wi-Fi from the Wi-Fi icon on the macOS / OS X menu bar.
Is it only your Mac computer that is not "remembering" the network, and other wireless devices are remembering the network?
If yes, is this your Mac computer that you mention in your profile that is running OS X El Capitan (10.11.6)? Or, have you updated to Sierra?
Did not work. I still get the Wi-fi network xxxxxx requires a WPA2 password window when I want to use the wi-fi.
Followed your instruction and tried to enter the "/Library/Preferences....
But when I press Go it only opens a window with the desktop listing.
??????????
Thanks,

Don't use the quotation marks.
Just enter: /Library/Preferences/SystemConfiguration/

Did get to that file and followed your instructions, but did not work.
Then just out of desperation I went through the diagnostic option,
that updated the keychain folder, and somehow I seem to be OK now.
No need to enter the password!
Anyhow, just wanted to thank you for your assist.

Yes, this is on my MacPro (2016) and I'm running Sierra. I have run out of idea with this issue. That is why I posted.
Thanks,

Did not work. Not sure I want to rename the Network, I have other devices using it. I don't see why Sierra would be the issue since the same problem was there with the previous OS.

Got it!
Thanks for your help Bob!

You're very welcome! I'm glad you got it worked out ...
