Wireless Joint

Well I received my actual home internet modem today. Speed was solid at first 25/4 but then with 5 minutes dropped to 3/1. Spent some time with tech support on the phone and they couldn't figure it out either as they agreed that it shouldn't be dropping like that. Have elevated call with next level ...

So the trial SIM is locked to the Franklin. Does anyone know if the actual plans sim is locked to the TM-RTL0102
LTE WiFi Gateway?

Running a Mofi4500. Can anyone tell me what is happening in this speed test? Why am I seeing the huge spikes and valleys?

What is happening here with this speed test? Why do I get the negative spikes?
