MediaTek (Ralink) RT5572 is 802.11(abg)n - http://en.wikipedia.org/wiki/IEEE_802.11n-2009

In contrast to:
MediaTek MT7610U is 802.11ac - http://en.wikipedia.org/wiki/IEEE_802.11ac
http://www.mediatek.com/en/news-events/mediatek-news/mediatek-first-to-bring-80211ac-1t1r
https://wikidevi.com/wiki/MediaTek

Notice the difference.
