Your device is probably certified under the FCC Part that requires it to not emit any harmful radio frequency interference and accept all RFI. So, if it isn't functioning correctly maybe the best thing is to report it to the seller and ask for a RFI fix. Probably won't do you any good because they most likely have decided protecting it against RFI isn't worth the cost.

This isn't just a wireless communication problem. Many device manufacturers go el cheapo when it comes to RFI unless some other regulation requires them to add the cost.
