T-Mobile High-Speed Internet Gateway-Gray

the 5G is inconsistent during day time.  I got like 1.5 Mbps at this time, and then 5.7 Mbps at that time.   Most of the time i saw the speed is up to 180 Mbps is after 11 pm.  This will not make any benefit at this pandemic timing while my wife, and daughter are working from home, and remote learning, respectivetly.  They both do video conferencing and to tell you the truth, my daughter's google classroom was a nightmare, which she could not see anyone else face (voice only.) and my wife keep got voice dropped out and video lagging during the video conferencing.  

I rather they give me an option to choose between LTE and 5G (just like on your android phone where you click on mobile network and you can turn off 5G and just solely connect on LTE network) because T-mobile LTE speed has been consistent like +80 Mbps d/l and 50 Mbp u/l in my area.
