> Did yours have a particularly old Wi-Fi card in it? From lspci: 03:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01) I don't know whether that is an old card or not. I think the laptop was in the $300-$400 range when we got it. Inspiron 15-3551, came with Ubuntu pre-installed, which has since been swapped out for Debian. This Dell support link [1] seems to confirm that it is 2.4Ghz only.
