Problem

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.

Guaranteed Fix

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.

Network Setup

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.

Solution

Description

After many months of having this issue with intermittent WiFi connections and sometimes losing connectivity for hours at a time, Bug 1108801 on the Red Hat / Fedora bug tracker seemed to hold the solution for me.

As described in Comment #12 on that bug, Realtek (the manufacturer of my wireless card) has updated drivers for my RTL8188EE wireless card that are NOT included in the Linux kernel / Fedora by default. So, my solution was to manually download the source code for the drivers, compile and install the code onto my computer, and then reboot. After doing this, I have not had any of the issue that I used to have with staying connected to WiFi networks!


How to fix

The commands I ran to install the drivers from Realtek's GitHub are as follows. Make sure you have already installed the git package from the Fedora software repositories!

git clone http://github.com/lwfinger/rtlwifi_new.git

cd rtlwifi_new

make

sudo modprobe -rv rtl8188ee

sudo make install

sudo modprobe -v rtl8188ee


Disclaimer

As of the time of writing this, I haven't had more than a day to ensure that this has resolved the issue entirely for me, but it resolve the issue I was having prior to installing the driver and rebooting. I can only hope this was the final solution, but if my problem continues, I will update the question.


IMPORTANT!

Every time that there is a kernel update for Fedora, you will have to download, compile, and install the drivers each time, as it only installs the drivers for whichever kernel you are currently using.

@cydrobolt – I'm not sure, I don't see it listed in the GitHub repository. However, you can still try and see if it resolves your issue. I'd be interested in hearing if it works or not.

+1, filing a bug is a good idea in such cases. It sounds like the OP may have a device that does not function properly after being suspended.

@randomuser My concern with this was that it wasn't a bug as much as a misconfiguration of the hardware.

@jflory7 Yes, I understand your concern; this answer directly addresses it: this behavior is not expected, you are experiencing a bug.

Hi randomuser and jflory; from my comment 5 of the bug I got the wifi working when I start the laptop (dell latitude d530) with just the wifi adapter on and no network cable; is there a way to reset the status of the wifi adapter on my laptop without restarting the laptop?
