I'm not sure what '802.11an' defines, but this old chip should not support that.
Then, maybe '802.11an' here means '802.11a/802.11n', but I still don't know the
relation with dual-band chip.
FYI:
802.11a: 5GHz band, CCK/OFDM
802.11b: 2GHz band, CCK
802.11g: 2GHz band, CCK/OFDM
802.11n: 2/5GHz bands, HT
