Macbook Pro WiFi Painfully Slow on Corporate Network, PC Works Fine Whenever I bring my 2015 Macbook Pro to a certain corporate environment and try to use WiFi there, it is painfully slow. At times, Google takes 5-10 seconds to load. Now, a Windows machine works just fine on this same network. What is more, when another person tries to use his 2016 Macbook Pro, he encounters the same problem.

Does anyone know what settings or configurations we can check either on the Macs or the network to fix this? 

Any advice is appreciated.
Try this setting, it helped me in the same situation :) In the network settings change the address of DNS servers to Google's ones: 8.8.8.8 or 8.8.4.4

For this go to Settings &gt; Network &gt; Advanced... &gt; DNS > press + and enter DNS address.



Or, vice versa, you may ask your system administrator for any specific DNS and probably proxy settings that your company might have due to security reasons and then enter them in the Proxy tab.
