I knew I had a Qualcomm Atheros chipset for Wi-Fi, but I didn’t know my model supported 5 GHz signals. The phones that I had in my home had 5 GHz support, so the only thing I needed to check was if my PC supported it. When I thought about upgrading my home Wi-Fi to 5 GHz, the first thing that I did was to check if all the devices I use support that frequency standard.
