Wi-Fi lag on S5

Having issues with slow pages loading

Perhaps your connection to WiFi is weak, or there is a considerable amount of traffic on your WiFi network, or your ISP is having issues.  Is this sporadically, all the time, always, or recent?  Maybe you have more than one app open that accesses data, maybe the quality of images or videos is too high for your network to support smooth loading without buffering.
