Change to non-metered connection with bluetooth (tethered)

[Kitte]

I am temporarily using tethering for Internet connection on my Surface Pro. Store apps won't install as before and (from reading here and elsewhere) it is probably due to the automatic switch to a metered connection. Instructions to change to non-metered involved right-clicking on the network from the charms menu. The Bluetooth PAN does not show up on that menu as a network.

I tried changing a setting under Devices to allow downloads over metered settings but that did not help.

Any other suggestions for how to change from metered to non-metered connection without using the charms menu?

Thanks,
Kitte
