My WiFi extender has been working fine for about 9 months, but the last 2 months it's been acting up, I went to reset it on the Tether app and it never restarted, the power indicator light just keeps blinking Blue and won't connect to the router anymore... I did reset it link I read to do in these TP Link feeds but it continues to just blink blue. What else should I try? It's not even a year old and I paid like $130 for it.
