Has anyone had a problem with a data plug (the small plug on the 3 plug outlet) no longer functioning? We had our house wired with 3 plug outlets in 7 rooms of our house. For some reason only 4 of the data plugs worked, while the others left the modem flashing endlessly during boot up. Now in the past few months, only 2 of the data plugs work with the modem. What could be the cause? I’m not sure where to start in reporting this. (Our internet main connection is locked up together with the main electricity box outside the house - only accessible by our electricity provider).
