New issue for me - Spiking Cadence and Power w/ Zwift Trainer

This is a new problem for me (coincidentally since the Z play were installed?)
The problem is particularly pronounced during training runs.
I get a message to spin faster and, when I do , the cadence drops for a prolonged period of time and never settles down. Same is true for power. It gives me a “more power” message and the power bounces all over the place when I do. Also, I’m riding with people who register a fairly constant 2.2-5 and I’m all over the place between 1.2 and 2.8. Should I put a wifi booster in my basement? Again, this is a fairly new problem. Thanks
