Slow speeds on certain devices

My wife and I recently started working from home.  The Orbi system has been working great and I get 90mb speed on all my devices, including iPhones, iPads, Macbook Air and a Lenovo Mini Windows 10 machine.  But for some reason, both our work machines have terrible network speeds, bouncing from 1 to 15mb.  Both are notebooks (HP Elitebook & Lenovo T460) and work fine on outside networks and in the office.  I have tried moving devices around the house with no luck.  Could there be any wireless settings on the notebooks that could be changed to better "see" the orbi network?
