My TP-LINK Archer AC-1200 Wi-Fi USB adapter has suddenly stopped working. It just cut out. I saw that the light was still blinking so I restarted my PC. When it launched the wifi was still of. I checked my phone, iPad and laptop and they still have wifi. Then I launched the tplink software and it said to connect a wifi adapter. I unplugged then plugged in the wifi adapter. It is connected through the include extension cord. When I plugged it back in the light didn't turn on. Plz help
