Purchased home from previous owners. Had no idea we had the ruckus box until my very techy smart home installer brother came and got all excited about it. He hadn't worked with ruckus but was able to set it up for us. It worker great, internet was great for 1 day. Now very sluggish. Keep in mind I have no app or anything he did it all without using an app (via laptop). Do we need to download a ruckus app? And what do I need to do to get support,? We worked from home need good internet. My brother isn't familiar with ruckus and isn't able to come help me for a while. Please help
