After leaving my Fedora 20 laptop running overnight, I open it back up and it prompts me to re-enter the password for my home WiFi network. The password is already typed in and censored, but it wants me to to confirm and hit Connect.
I have deliberately made sure the password I am typing in is correct.
Once I type the password into the prompt, I press Connect and the prompt disappears. About five to ten seconds later, without displaying an error message of any sort, it brings up the exact same prompt with the password already entered. Just to be sure, I've tried just pressing Connect without editing the password, and I have also retyped the password and tried again to no avail.
As of right now, the only way I know I can indefinitely fix the problem is by restarting my laptop, which leads me to believe that either my home WiFi network is misconfigured in the WiFi Settings, or there is something that Fedora isn't handling properly.
Ideally, yes, I could just restart my laptop, but for example, let's say I'm uploading a significant amount of files over FTP, and if I restart my computer, that means I have to reupload a few thousand files because I have no idea which ones have been uploaded, which is just a huge delay.
My network is a Westell modem connected to an Apple AirPort Extreme router. As far as I know, it's a pretty standard setup.
The router handles DHCP and NAT, which does cause a small problem with the modem (a double NAT), and AT&T told us that if we want to use the features from our AirPort Extreme, we will have to deal with it. But it hasn't affected Internet usage on any other devices for the past year and a half since we set it up.
This is the AirPort Utility's description of a Double NAT, if it helps any:
This AirPort base station has a private IP address on its Ethernet WAN port. It is connected to a device or network that is using Network Address Translation (NAT) to provide private IP addresses. Change your AirPort base station from using DHCP and NAT to bridge mode.
Using bridge mode disables some of the most important features of our AirPort Extreme base station, including guest networking. But as I said previously, having the Double NAT hasn't affected Internet usage on any other device for the past two years.
