So basically I recently started living with a relative and that's when this router started having issues. What happens is sometimes the router will drop a few or all of the devices on the network every 5-15 minutes or so. I'm not sure if it does the same for devices with a wired connection because with all our devices we connect to the router wirelessly. Usually I'm able to reconnect after a bit but it's annoying. When I am home alone however there's no problems so I'm assuming that its the number of devices connected to the router? Honestly I'm not very networking literate so I'm not sure what other details I need to provide about this problem. We tried updating the firmware to the newest version on the Dlink website but the issue persists. Here's the support page:
