Why is my mac since update el capitanslow wifi ok on the cable

Since then until this day at el capitan slow on wifi ok on cable

A general comment in El Capitan 11.4:

If you need to fix slow WiFi on OS X El Capitan, you may restart your router and modem, unplug them for about 30 seconds to a minute. If this fixed not you can try to disable your wireless on your Mac. Click the WiFi icon, then turn off WiFi. After a minute turn it back on. This can fix many problems.

Other possible fixes, including clicking on open network preferences, and then click Advanced to change the order of your computer must connect, options to remove a WiFi network and much more. Sometimes, deleting a connection and add it again will fix the problem.
