I have an Acer Aspire 7740G with a Atheros AR5B93 and I want to put a Intel Dual Band Wireless-AC 7260 in it but the Atheros card only supports 2.4GHz and the Intel card supports 2.4/5GHz and I was wondering if I would need to change the antenna in the laptop to be able to take full advantage of the card. Thanks.
