OS X yosemiet WiFi disconnect how to do? Small knitting brought Yosemite WiFi swap solution, a lot of friends said that after the update ypsemite WiFi wireless network connection is easy to disconnect, how to do? Let's get to know each other.

The first step is to manually delete the network configuration and properties files and have the system recreate the new configuration

Manually removing plist files involving network configuration is the first step you should take, and these methods usually work even when dealing with the most stubborn wireless connectivity problems with OS X systems.

1. Turn off Wi-Fi connection from wireless configuration

2, open the Finder, use the shortcut key Command+shift+g Open the Path box, type the following path:

/library/preferences/systemconfiguration/

3, in the open folder to find the following files

Com.apple.airport.preferences.plist

Com.apple.network.identification.plist

Com.apple.wifi.message-tracer.plist

Networkinterfaces.plist

Preferences.plist

4. Create a new backup folder on your desktop and "move" all these files to the folder, just in case.

5. Turn on Wi-Fi again after reboot

This method allows OS X to force the recreate of the wireless profile, and if it still does not return to normal, proceed to step two.

Step two, create a new Wi-Fi network location, and configure DNS

1, from the system configuration to open the network configuration

2, click the network location "locations" pull-down menu, select "Edit Location", click [+] plus button, customize a name click to continue.

3, choose your wireless network in the "Network noun"

4, click the "Advanced" button, switch to the DNS tag

5, click [+] plus button, type a fixed DNS server address such as 8.8.8.8

6, switch to the hardware tag, set MTU value of 1453

8, click the Application button

Rerun some applications that require network access, test whether the wireless connection has returned to normal speed, and if none of the above methods fail, you can reset DNS and Wi-Fi problems by trying the following methods.

Third step, unloading the network DNS configuration through the terminal tool

1, through the utility or search tool to open the terminal Terminal, type the following command

sudo launchctl unload-w/system/library/launchdaemons/com.apple.discoveryd.plist

2, after tapping the return type Administrator password

3, type the following command to reset the DNS configuration

sudo launchctl load-w/system/library/launchdaemons/com.apple.discoveryd.plist

4, hit the carriage return waits completes

Rerun some applications that require network access to test whether the wireless connection has returned to normal speed. If you are still unable to recover, it is recommended that you install the Yosemite system in a clean manner.
