The iMac (21.5-inch, Mid 2011) only supports 802.11 a/b/g/n. This is useful to know since many newer WiFi Routers are now supporting 802.11ac and there’s a big difference between the 802.11n and 802.11ac. The latest routers from Comcast, as part of xFinity X1 upgrades now support 802.11ac speeds.
User’s of older iMac’s can take advantage of the higher speed by getting an adapter.
Your best bet is the NETGEAR WiFi USB 2.0 Adapter - AC Dual Band (A6200), which sells for about $24.99 on Amazon.
Mono price has a Dual-Band 802.11AC 600Mbps USB 2.0 Wi-Fi® Adapter for $12, but your just getting speed of up to 433Mbps. So you are basically getting the 802.11n speeds.
