Reverse terminal command

[iAlexG]

I've been troubleshooting serious battery drain on sleep (30-40% in 12 hours sleep) and ran a command to stop macOS searching for WiFi.

sudo pmset -b tcpkeepalive 0

For reference, what command needs to be run to undo this in the future?

Ordinarily, commands like that use 0 to disable a feature and 1 to enable, so just swap the 0 there for a 1.
