I am sorry to see there was not any input from the forums participants.
First thing I would suggest is swapping out the modem you are currently using, if you still have the problem that would rule out the modem.
Are you using your own router? Do you see more wireless network options at your new place? There may be interference from new neighbors.
Have you tried different channels on your router? Do you have the problem with both 2.4 and 5 GHz.

Bluetooth connectivity can be greatly impacted by a heavily congested 2.4 ghz wireless frequency nearby. Do you have a cordless phone, microwave oven, fluorescent lighting, or baby monitors close to the bluetooth devices? Are your bluetooth devices close to the router? You can try moving the devices away from the router or even try changing the channel of 2.4 ghz band on your wifi network.
Being in an apartment you may be SOL though if the source of the interference is your neighbors.
Is there a Spectrum store near you? If so, you can try exchanging your combo unit for separate modem and router units. As in the other thread, perhaps that particular Ubee model throws out more interference for bluetooth signals than others.
I personally have one of the Spectrum branded Wave 2 router and have not noticed any bluetooth interference...and I have several devices within a few steps of the router.
