@Heidi_Alp Thank you for your reply. Any idea where I can find a cable? Can just an ethernet cable only be used from the cable box to mesh to run wireless computer upstairs for the single mess unit?

I purchased the 3 pack AX3000 but 2 units seem to be working great. Can another cable be purchased so I can connect this unit in my daughter's house (different network, router, location, account)?...
