First and foremost: are you experiencing frequent symptoms of an under-powered or overwhelmed router? If you can't get a Wi-Fi signal everywhere in your home (and have considered getting a Wi-Fi extender or a second router), that's a good indicator you're a good candidate for an upgrade. If you frequently have network-related congestion issues, like slow web page loading or stuttering and buffering video playback, that can't be chalked up to a slow broadband connection then it's a good sign that your router isn't up to the task of serving everyone in your household.
Second, was the router a freebie? If it was supplied by your ISP (whether as a router/modem combo or a stand-alone unit) there's a good chance it's not up to snuff. ISPs aren't in the business of handing out extremely high quality routers, and generally speaking most modem/router combination units are junk.
Even if you aren't noticing problems, you should also consider the age of your router, too–both in terms of the actual age of your physical device and the age of the particular model. You might have bought the router two years ago, but if the model itself is from 5 or more years ago, there's a good chance that you're playing with outdated router tech and could benefit greatly from upgrading. If you're still using a single radio/band Wireless-G router from 2010 or before, for example, you're essentially using a bicycle when you could be using a spaceship.
