QCA9377 upgrade options

I got an inspiron 7375 back earlier this year to use for school this fall. All has been fine using the laptop at home and on the go a bit, but unfortunately wifi reception in a few of my classrooms isn’t very good (new campus, still finishing installations). As such, I’m looking to upgrade the qualcomm QCA9377 that came in this laptop to a dual band solution of some sort, to help with reception issues and speeds. Is there a dual band card I can get for this laptop that would work? So far I’ve tried an intel 7260 from an older chromebook but it doesn’t seem to work right, consistently disappearing and reappearing in device manager on the windows side and throwing tons of error messages when I try to connect from an arch live environment.
