Question

WiFi stays connected, BUT from time to time Internet access is gone

Hello all,

I have the infamous WiFi issue in a form that is not the most popular.

iMac late 2013, came with 10.10.1, was updated to 10.10.2, then fresh install of 10.10.3. In all three stages I have experienced the same issue: from time to time I loose my WiFi connection to Internet. WiFi shows always on and, although I did not try, I'd say I could ping the routher when this happens, but it's like DNS stops working. I read something about DNS servers being banned... how can one avoid this? If I switch wifi off and on it works again. Setting IP6 link to local only worked for almost a week, but then the issue came back. Last thing I did was changing my DNS in connection properties to my router address (local IP 192.168.1.1), so router acts as DNS server.

Anyone else had this? Did you solve it?

All the best,

Juan.

iMac, OS X Yosemite (10.10.3)

Hi there DroningForever,

As I understand it your mac stays connected to your Wi-Fi router, but you cannot actually get to the internet. The next time that it happens, I would recommend using the Wireless Diagnostics on Yosemite to help you determine what the issue with the connection could be:

OS X Yosemite: About Wireless Diagnostics

Wireless Diagnostics analyzes the Wi-Fi network your Mac is connected to, and provides solutions to help resolve wireless connectivity issues.

If you can connect to your Wi-Fi router, but have issues loading webpages, sending or receiving email, streaming music or video, use Wireless Diagnostics to analyze the network’s connection to the Internet. After Wireless Diagnostics has completed an analysis of your Wi-Fi network, it lists any issues it finds and offers some solutions.

Wireless Diagnostics collects detailed logs you can provide to a network specialist, network administrator, or an IT support person.

Wireless Diagnostics generates a compressed file containing details found during the diagnosis that is saved to the desktop of your Mac. The file’s name starts with WirelessDiagnostics- and ends with .tar.gz. This file may be useful to your network administrator, service provider, or IT support person.

Note: Wireless Diagnostics doesn’t change your network settings.

Quit all open apps.

Try to join the Wi-Fi network you’re having problems with (if you are not already connected).

Hold down the Option key, click the Wi-Fi status icon in the menu bar, then choose Open Wireless Diagnostics.

Enter your user name and password, then click Continue.

Follow the onscreen instructions to analyze your network connection.

For more information about using Wireless Diagnostics, see the Apple Support article About Wireless Diagnostics.

Thank you for using Apple Support Communities.

All the best,

Sterling
