The WIFI Repeater worked eight months without any problems, then you could not connect. Neither WLAN nor via Ethernet cable, the problem was to be solved, and a reset with the reset button does not solve the problem.
That is why CM3 written that withdrew to the legally correct, but customer unfriendly position. I had to prove that the defect existed at delivery. However, they offered me in buying a new repeater 50% discount.
