Netgear Nighthawk R8500 only turns on

My WiFi router only turns on, I see the other lights flash for a second when I turn it off and back on. Nothing else works, it only turns on and does nothing else, I am not sure what I should do?

Re: Netgear Nighthawk R8500 only turns on

What color is that power light when it turns on? 

Orange/amber? 

might have corrupt firmware and be a canidate for a tftp procedure.

make sure to enable tftp from within windows if you're on windows.

and a video of someone using tftp for example.

I have a MacBook Air and this laptop does not have an Ethernet input, would it be possible to do it some other way?

Also, yes, it’s always a solid amber light for the power

Re: Netgear Nighthawk R8500 only turns on

here's a guide on doing it with a mac. The thread is about an R7000 but the process is the same.

If you don't have a device with an ethernet port, then you'd need to get a usb-----ethernet adapter because it needs to be hardwired in to do.

Hello, I purchased a USB—Ethernet adaptor but now I’m coming across another problem, everytime I attempt to put the firmware update through tftp, I get a “Transfer timed out.”

   Could be a hardware problem, or your "attempt" could be bad.

 

   The TFTP recovery scheme is a multi-step procedure which offers
multiple opportunities for user input, hence user error.  By itself,
saying that you attempted it doesn't say much.  Especially when
using a command-line program, copy+paste is your friend.

 

   See, for example:
