Scott, I currently have two WiFi bands to choose from courtesy of Xfinity/Comcast. One band is 2.4GHz; the other is 5GHz. The desktop PC I usually use currently utilizes a Cisco/Linksys AE6000
adapter. Mozilla Firefox is my default browser. Curiously, if I'm not mistaken, pictures display properly on Firefox more consistently when I'm using the 2.4GHz than when I'm using the 5GHz band. When I use the 5GHz band, I often have to refresh the Firefox browser or clear cache from Firefox in order for a number of pictures to display properly. What could be the reason why this is the case, Scott?
