Since swapping our 7150 C12P with a replacement sent to us by Ruckus, things had been working. It worked out of the box without setup, and I didn't bother updating the firmware or changing the settings, partly because I didn't have the passwords and stuff to log into the system. In recent days, our phone calls have become very choppy or dropping (we use a Wifi booster because we get no Verizon signal here) and the internet speeds are dropping drastically. Speedtest will show 1 Mbps for several seconds before ramping up to a mere 80 Mbps (we get at least 200-400 Mbps depending on the place in the house). I'm thinking it might be because the settings on the 7150 switch are generic from the last user or factory and need to be optimized. Please advise.
