After all, a disruption anywhere along the chain between your Mac and a distant server could cause an outage, and it’s not always obvious where to look. I suggest trying each of the following steps, in order, until you’re able to connect again. 1. Try another site or app To make sure the problem

isn’t restricted to just one website, try visiting another—preferably one that’s highly reliable, such as Google.com. Similarly, to make sure the problem isn’t just your current app (such as your email program or Web browser), try connecting to the Internet with another app. If only one site seems to be having problems, try visiting Down For Everyone Or Just Me and entering the problematic site’s URL. The service will tell you whether computers elsewhere on the Internet can successfully connect to the site. 2. Use Network Diagnostics Certain types of network problems may cause your browser to display a Network Diagnostics button. This is OS X’s way of offering to help debug your connection problem, and I suggest accepting that help. (If you don’t see a button, you can launch Network Diagnostics manually. To do this, choose Apple menu > System Preferences and click Network. Click Assist me, and then click Diagnostics.) The Network Diagnostics utility will guide you through a series of questions and tests, ranging from checking your ethernet or Wi-Fi connection to network configuration and DNS servers. Sometimes the utility can repair problems itself; when it can’t, it usually provides more detailed information about the nature of the problem and offers suggestions f
Many Mac users are facing Wi-Fi and networking issues after updating to OS X Yosemite. These problems range from slow connections, frequent disconnects, or mac dns probe finished no internet not being able to connect to the internet at all, despite being on apple dns server address a Wi-Fi network. If you're facing such problems, here are some tips that might help you fix them: Remove Network Configuration

Files Many people have said that their problems have been solved after deleting network configuration related plist files. To do this: Turn off Wi-Fi from the menu bar. Navigate to /Library/Preferences/SystemConfiguration/ in Finder by pressing http://www.macworld.com/article/2028982/mac-troubleshooting-what-to-do-when-you-cant-connect-to-the-internet.html ⌘ + Shift + G. Select the following files: com.apple.airport.preferences.plist com.apple.network.identification.plist com.apple.wifi.message-tracer.plist NetworkInterfaces.plist preferences.plist Copy these files in a safe location so that if anything gets messed up, you can easily restore them. Delete the files. Reboot your Mac and enable Wi-Fi again. OS X should generate these files again, and hopefully fix your problems. Change DNS Server You can try changing your DNS server if you find http://www.iphonehacks.com/2014/11/wi-fi-problems-mac-os-x-yosemite.html that your Wi-Fi is connected, but you're not able to connect to the internet: Open System Preferences from the Apple Menu. Click on Network Select Wi-Fi on the left and click on Advanced. Select the DNS tab. Click on the + button at the bottom to add a DNS server. While there are a lot of DNS servers available, we've found Google's DNS servers to be quite good. To use Google's DNS add one or both of these IP addresses: 8.8.8.8, 8.8.4.4. Once you've done this, click on the Hardware tab and change Configuration from Automatically to Manual. Then click on MTU, and select Manual. Enter 1453 as the MTU Number. Click on OK, then on Apply to bring these changes into effect. Quick and open the apps in which you were facing problems, and if everything goes well, you'll no longer face connectivity issues. Refresh discoveryd service Another thing you could try is refreshing the discoveryd service: Open Terminal from Spotlight or Launchpad. Enter this command, press enter and enter your password: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist Now run this command to start the service again: sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist Other tips you could try include switching to 2.4GHZ N network or turn off Bluetooth

The Network Diagnostics utility will guide you through a series of questions and tests, ranging from checking your ethernet or Wi-Fi connection to network configuration and DNS servers. Sometimes the utility can repair problems itself;
from dropping wi-fi connections, to an inability to connect to the outside world despite being connected to a wifi router, even suddenly and strangely slow internet speeds. These network issues seem to occur most often on Macs that have updated to OS X Yosemite from Mavericks rather than those who performed a clean Yosemite install, which could suggest the issue has to do with improper network setting and preferences, or even a corrupted file somewhere. That’s a good thing, because it should mean a resolution is fairly easy to implement, as we're about to show you. It should be noted that it’s difficult to point to a single cause for sudden and unexpected wireless troubles with any OS X version, and there may be different causes for different users. Accordingly, it's challenging to offer a single solution to the Yosemite Wi-Fi problems that users are experiencing. With that said, we’ve been able to resolve the problem for many Macs by using the steps outlined below. This involves editing some system level configuration files, and you should probably start a Time Machine backup before proceeding just to be on the safe side of things. 1: Remove Network Configuration & Preference Files Manually trashing the network plist files should be your first line of troubleshooting. This is one of those tricks that consistently resolves even the most stubborn wireless problems on Macs of nearly any OS X version. This is particularly effective for Macs who updated to Yosemite that may have a corrupt or dysfunctional preference file mucking things up: Turn Off Wi-Fi from the Wireless menu item From the OS X Finder, hit Command+Shift+G and enter the following path: /Library/Preferences/SystemConfiguration/ Within this folder locate and select the following files: com.apple.airport.preferences.plist
com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
preferences.plist Move all of these files into a folder on your Desktop called ‘wifi backups' or something similar - we’re backing these up just in case you break someth
