Hi, the extender has been working for months without any problem, but it suddenly stopped and when I relocate it, it seems to turn on, blinks all the lights (with red Signal, too) and turns off after a few seconds. I have reset it and tried to reconnect several times close to the router installing app but my mobile cannot find the extender as it doesn't exist. Each time when I connect to the electricity it reacts the same way. How can I fix it? If you can give me any advice, it would be fantastic, thank you!
