Hi,

Please hard reset the extender and give it a go.

If still the same, you can contact our tech support to check the warranty service.

I had purchased the above product last month from Amazon and the product was working fine till yesterday. But since yesterday, the device is not getting on and no led is glowing even after powering up the device. I have checked it in multiple power outlet but no improvement. Kindly help in the matter.
