AC2200 Nighthawk X4 WiFi Mesh Extender Model EX7300v2 Amber/Orange Led

Hi guys.

I need help with this device. It got stuck on the amber/orange LED. I tried to reset it many times but nothing happened. I even tried to upload firmware with TPTP and nothing. It seems there is no connectivity. Any tip? Thanks!

If you can't get it working with tftp or nmrpflash, then it might be a hardware warranty

what is orange/amber? What led?

if tftp doesn't work, nmrpflash has worked for some. But even with tftp, its sensitive to timings. sometimes you have to try a few times. 

are you on windows? if so, follow this guide
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash

It just shows that light with no changing or blinking at all

try tftp again. again its sensitive to timings. 

nmrpflash is a little less sensitive so you can always try that first

[Viktor1979]

Nothing, it keeps running and shows nothing

I think the problem is related to communication. When I set my Network to local IP it doesn´t recognize it. It shows default gateway not available. I tried with  192.168.1.1,  192.168.0.1

Hi, it´s me again.

I tried to connect the Extender directly to my Pc and I set the static IP as it says in: https://kb.netgear.com/000059633/How-do-I-upload-firmware-to-my-NETGEAR-router-using-a-TFTP-client-o...
Tftpd64 does nothing, it just runs but nothing shows. I tried to ping  192.168.1.1 (Extender) and no response at all. 

I tried connecting the extender to the router by ethernet and the router port blinks but nothing shows on the DHCP Cliente List, as if nothing were connected to it. 

Any other idea? Thanks

If you're hardwiring the ex7300 into the router and the ex7300's ethernet light is on, it might not be corrupt. 

When its hardwired into a router, it needs to be switched over to access point mode (switch on the side). Switch that over to access point, plug it in, and then push and hold reset for up to 30 seconds. Then hardwire it into your router

[Viktor1979]

Already connected as access point following your instrucctions. It´s not shown in the router dchp client list yet. The orange light doesn´t move at all, not even when I power it. Pretty strange this.

[plemans]

is it still within warranty?

[Viktor1979]

No, I wish it was. 

I think if the extender showed some blinking there would be a chance to do something but it ´s absolutely frozen 😕

[Viktor1979]

Not, it is not. Still not working

sorry, meant hardware failure.
