Learned the hard way that relatively recent equipment like a Dell Inspiron 17R/5737 with Windows 10 does not do 802.11n despite Dell claiming “Dell™ Wireless 1705 802.11b/g/n with Bluetooth v4.0”.
I discovered it while hooking it up to a Huawei E5577Cs which by default is configured for 5Ghz 802.11n and the Dell not seeing it at all despite up-to-date drivers.
Both an iPad and an LG Android phone would immediately see it.
Switching the Huawei to use 2.4Ghz WiFi immediately made the Dell see it.
Windows 10 installed an Intel® Wireless-N 7260 driver and I could not find any settings that make the 802.11n work.
