Hello. I have the 3 pack M5. One of them, which is the slave one, does not function properly as every time i try go switch to the location where it is located, there is no internet. I even tried connecting it via Ethernet from the main deco but still no internet. I also tried switching the said slave deco with main one, but what happened was every deco's internet was gone. I think this one specific deco from the 3 is defective. Please advise.
