Prevent wifi from disconnecting during sleep mode

Anonymous

Hi,

 I have a SP4 and often times I find that the wifi is disconnected as soon as my device goes into sleep mode. Is there a way to fix this? In power & sleep settings I have set the option under Network connection to "never" i.e. when my PC is asleep and on battery power, then my device shouldn't disconnect from the network.

 Also, if I am downloading/running some application, then shouldn't the device be awake instead of going to sleep mode?

Regards

Suman

    Hi Marrion,

    Thank you for the reply. I am trying to run the Surface diagnostic check for my SP4. I get the following message

    Regarding selective suspend, I don't see that option (attaching a screen shot).

    Request your help.

    Thanks and regards
