i never suggested 'wildly adding more and more routers without knowing where the dead spots actually are'.
stop lying and trolling.
what i said was if there's a dead spot, simply add a router for additional coverage and link the two. done.
a mesh unit is an even better choice but not required.
you have no clue what you're talking about and you're not fooling anyone.
nope.
if you want to use a ridiculous car analogy, what you're suggesting is someone downloading a bunch of apps to try to diagnose the car despite not knowing what they're doing, versus taking it to a mechanic and have it properly fixed.
