> 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.

Yeah, thats an ath9k card (802.11n). 5Ghz was optional in the 802.11n days, so only higher end devices tended to support it.
