Good evening everyone.

Yesterday I buy my 300mbps Wirless N Router Model: TL-WR840N (V5), S/N: 217C621006736, MAC: B0-4E-26-**-**-86.
After booting up the first time everything went fine. w-lan, lan and Internet works great.

Later on I changed the ssid and the w-lan password. So far so good.
I switched off the router and placed him on his workplace.

After plugging in the power the router try to boot.
And there we are. Only the power LED is blinking. Nothing else.

The wireless devices got an ip. But it's not possible to connect to the Web interface of the router. Even a ping is not possible.

So I tryed a hard reset. I gently pressed in the wps/reset button. You can feel if it's pressed ;)
After 8 seconds LED's also blinking. Nothing work.

So I tryed pressing it up to 1 minute. Nothing work again.

I tryed the 30 30 30 reset. Nothing helped.

The on/off LED is always blinking in the same time frequenz.

I can't connect.
I havent updated the routers software.
I don't know the software version that's preinstalled.

Are there any other steps I can do? Or is the router dead?

-best regard
