[AZ] Latency Spikes all day

Hello,

I've been getting a lot of latency spikes lately in both directions and it's becoming much more difficult for me to do my job as a distance-teacher. I have had a technician come over to the apartment and he stated that everything was fine. I've replaced, reset, and reseated (Unplugged - re-plugged in) all the connections on my end multiple times and nothing has fixed the issue. 

Is there anything else that can be done to minimize the data-loss especially when doing video tutoring in the evenings?

Thanks ahead of time.
