My Macbook Pro WiFi is getting slower unless I reboot
I only address uninstalling Jack Audio.

You can uninstall Jack by looking here: http://www.jackosx.com/Documentation.pdf

Uninstalling Jack OS X
To uninstall Jack OS X, double click the “Uninstall JackOSX” file located in the Jack
folder, in your main Applications folder. A Terminal window will be displayed, and it will
prompt you for your Mac’s Administrator password. Type it, press Return, and all
components of Jack OS X will be removed from your system. Please note that when
typing your password into the Terminal window, it will not seem as though your
password is being acknowledged; this is not the case – just keep typing and press
Return, and it will work.
If you’d like to uninstall a previous version of Jack OS X, this is done automatically for
you when installing the new version.
