Whereas without the least problem (Linux 3.14, debian jessie, driver ath9k). TP-LINK wifi cards will always have become accustomed relatively well with respect to the conversion of its cost and quite well because of the parameters used cipsetom Atheros. Annexed 2 dBi antenna is not to blame for operation in indoor conditions.
