I am buying a router. But it says 2.4 GHz is that not that great. So I want to know if it supports. Just curious what types of WiFi it supports: A, B, G, and/or N.

According to the specifications, the fourth generation iPod touch supports 802.11b/g/n on the 2.4GHz band.

The first through third generations support 802.11b/g, while the fifth generation supports 802.11a/b/g/n on both the 2.4 and 5GHz bands.
