> Most people simply use the router rented out from their internet provider (for free), and in most cases just make it work somehow (instead of buying a new device just for routing they would rather acknowledge that wifi doesn't work well in some parts of the apartment and live with it). Sure sometimes it's shitty and I have to reboot it to get it to work again, but I can live with it if it's not too often.
OTOH, for lots of people the cost of a new router is a small fraction of even a years ISP service, so if it significantly improves performance of the internet service you are paying for monthly, and is usable for several years, its worth it.
