Hello, for the past couple of days the house's internet has been consistently spiking in terms of ping, the download and upload speeds are fine however, at moments the ping spikes get so bad that there's a 3 second delay between me speaking and students and tutors hearing me in discussions. I don't think this has been an issue for a long time but I have only lived with my grandparents for a few weeks now. They are using TP-Link archer C1200 and the website shows a CPU load of 100% with 6 devices, most of which are idle. Could you help me with a couple of tips for the ping?
