Hello,

Unfortunately I installed the wrong firmware on my 3-month old device tp link WPA4220. I installed the firmware of another tp link PLC device.

Since then, my computer won´t recognise the device when connecting it. When I plug it in I can see the lights and the wireless connection, but it has no internet access. The powerline led is also off and sometimes blinking.

I have tried the reset bottom with no luck.

Is there a way to make this device go back to the original firmware? or shall i throw it away already?

Thanks!
