My wife's computer an IdeaPad with Windows 10 64 bit can only see the 2.4 Ghz band from my Netgear nighthawk router. Her adapter support the 802.11b, 802.11g and 802.11n protocols. I have an IdeaPad with Windows 7 and I can connect to the 5GHz band with an adapter that supports 802.11a, b and c protocols. I am confused.

    Sometimes proper driver may require to work the device/hardware. Check the Wi-Fi driver of your wife's Ideapad which is legitimate and configured properly. You can uninstall the driver and again re-install the same, however Windows can install it automatically after rebooting. Also distance is a matter.

    802.11 b/g/n only support 2.4ghz. 802.11a and 802.11AC support 5ghz. It's not a driver or OS issue. It's a limitation of the supplied hardware

    Thanks so much for your response. I thought something like that was the case but was not able to find anything definitive that stated that fact.

    Very interesting read thanks for the link. Not sure why I was not able to find that earlier, probably googling the wrong phrase.

    Wi-Fi can be finicky. I have a tablet that depending on where in the house I am I can detect bot or just one. So it may come down to signal strength and the quality of the receiver in the device.
