BRI Max Mini Slow Speeds AT&T

I am setting up a new BRI Max Mini device with AT&T FirstNet and my speeds are very slow. I have searched on this site and found some helpful tips but nothing is getting me up to speeds that I should be getting. I am usually getting around 2-3 Mbps download and the upload is too slow to even register.

Here are the numbers when connected to FirstNet:
RSSI: -62dBm
SINR: 14.2dB
RSRP: -91dBm
RSRQ: -17.0dB

Any help will be greatly appreciated.

Thank you!
