Users of Mac OS X Mavericks and earlier have reported facing WiFi related issues after their MacBook Pro comes out of sleep. In most cases, the WiFi-related issues have occurred after installing OS X Mavericks on a MacBook Pro. In later macOS versions, this problem has been resolved. Having steady Internet connectivity is crucial to complete both work tasks and routine operations. No need to worry: the majority of sleep-related WiFi issues on MacBook Pro machines are easy to fix.
Here’s what to do if your MacBook Air/Pro wireless connection is slow or WiFi won’t connect after being in the standby or sleep mode:
WiFi and Bluetooth connections might interfere with each other. If you’re not much of a Bluetooth user, disabling it can help.

Earlier Mac models used PRAM (parameter random access memory), a limited amount of battery-backed memory storing the data needed to load the operating system. Later on, it has been replaced by NVRAM (non-volatile random access memory), a limited amount of memory used to keep system settings like display resolution, sound volume, startup disk information, time zone, etc. Resetting NVRAM might help to fix the settings related issues.
Note: the NVRAM (PRAM) won’t impact user data. However, specific system preferences might change.
Deleting the Bluetooth .plist file is an emergency option in case modifying the Bluetooth settings didn’t resolve the WiFi connectivity problems.
The above methods should help in fixing your Apple MacBook Air/Pro wireless connection issues. If none of the fixes helps, try contacting your internet service provider to check if the WiFi router settings are correct. Believe it or not, the solution may be quite obvious:
