How do I keep my Mac connected to WIFI when sleeping when Setting preferred network doesn’t work
Few days ago, I started downloading a big file of 7GB and then went for lunch hoping my download will finish in 2-3 hours. When I came back, I saw download was at 2 GB interrupted due to request time out (No internet connectivity). I again started download and same happened when my mac book went into sleep mode. I realised WiFi is getting disconnected when mac book goes into sleep mode.
I thought okay, now I know the problem, I just go to system preferences and uncheck Wifi sleep mode like I am familiar with android devices but there was no such option and then I started searching on Google for this problem.
I got this link https://www.igeeksblog.com/mac-disconnecting-from-wi-fi-after-sleep-wake/ from web and I followed step by step guide given in this nice tutorial. Unfortunately it did not work for me. Basically this link says, Wifi network you connected with should be your preferred network. But even after making it as preferred, problem did not solve for me.
Then yesterday I suddenly found this option and it worked like rain drops in desert. I opened system preferences -> energy Saver -> power adapter and I saw this option “Wake for Wifi network access”. I immediately unchecked it. 🙂
Basically under energy saving option, apple disconnects Wifi network to save battery and it is checked by default. Once you uncheck this option, your macbook will stay connected to Wifi network even in sleep mode.
You don’t need to make your macbook never sleep as suggested by many tech people as it will severely affect your battery performance and really not good option to go for.
So, this setting has saved me from hell and thought to share with you. If you find this article useful, feel free to comment below and share with your friends.
