I have been noticing lately that my 2017 MBP with Touch Bar wifi connection isn't nearly as fast as it used to be. It is currently running Mac OS Mojave 10.14.1 beta. I would say this has been happening for at least a couple of weeks. I have tried killing all the applications that are using wifi, rebooting, restart modem and router, etc. When I run a test on speedtest.net, this 2017 MBP is much slower than my old 2012 Retina MBP and my iPhone XS Max. They're all on the same 5ghz wifi network and all within a few feet of each other, so the location in the house shouldn't be the issue. Any suggestions?
