You don't need to upgrade every two years. This is why:

1) There are only a few standards that changed. You didn't need to upgrade unless you bought a low-end device first and then upgraded to a high end for more speed on the same standard.

2) You need to also upgrade the clients to support the new standard. If you didn't upgrade the clients, the new router was a waste.

3) Speed differences are significat on paper, but not so much in real life.

- 802.11b = you can have SD video streaming with this link

- 802.11g = you can have 1080p video streaming.

- 802.11n = enough for UHD videos.

Between b and n, speed increase is ~10 times, but the ethernet was always at least 10 times faster than any wifi and with a *reliable* connection. So if you are using wifi for heavy data transfers other than live video on a *mobile device*, then you're doing it wrong.
