Internet throughput on Peplink

I installed a Peplink Balance 20 without realizing the throughput didn’t match what is provided by my ISP. My ISP throughput is 1200mb. The Balance 20 supports less than that. I upgraded to the Balance Two to take advantage of the 1000mb throughput. I am seeing the same throughput with the Balance 20 as I am with the Balance Two: 90 mb. Throughput testing directly to the ISP is 900-1200mb.
