We need wifi to spread the internet connection. So to spread the connection a wide range router is indeed required. So dilink is the choice. I can bet dlink provides the widest range among all routers. Its a really trustworthy brand. None can compete dlink in case of wider range.
The routrr is costly than others but one will always be a gainer buying this. it comes with a 1year replacement watrenty which is a document of its longevity. I'm using a dilink rounter since 5years without any problem till now. it's the best!
