It appears that most Nepali households use generic models of routers that cost about 20 bucks. While they're also available for sale on bestbuy site, there are some that cost 200 dollars. How big of a difference does a router make? Especially in Nepal where most buildings are concrete.

Can someone please recommend a decent one?

I looked at this and I'm really confused. https://www.bestbuy.com/site/searchpage.jsp?st=tp+link+router&_dyncharset=UTF-8&id=pcat17071&type=page&sc=Global&cp=1&nrp=&sp=&qp=&list=n&af=true&iht=y&usc=All+Categories&ks=960&keys=keys
