Calling all TP-Link community members, I need your help!  My old router recently died and I bought a new MR6400 router to replace it.  The location of the router is at a remote house in Africa and I am currently in the USA.  I have a family member who has zero to very limited technical skills who has kindly offered to do the installation of the new router.  Would like to have this family member do the most basic installation possible in Africa and also config the router just enough for remote management so that I may complete the more complex router configurations.  Can you please suggest the simplest and best way (Tether app or web browser) that the family member should use and what are the most critical configurations in the initial setup to ensure that I am able to takeover and conduct remote management from the US.  Thanks for your help!
