Constant amber power light on R6400 router
My Netgear R6400 router is not powering on correctly. I use it for both LAN and WiFi connectivity. It is not allowing internet access via either method. Both the Power and Internet led lights a...
Hi velvetwood,
1. Are you referring to the Internet light (planet symbol)?
2. Please make sure that you are able to go online straight from the modem (ISP's device).
3. You can try MAC spoofing. Check the link below for the steps.

It is either your AC adapter is heading South or as a result the firmware is corrupt. Just make sure
the adaopter is good B4 you do anything. If adaptor checks out try tftp to reload f/w.
Hi VE6CGX:
Thank you for the info. I just checked the output voltage of the adaptor and it is 15 volts. The adaptor is labeled as having a 12 volt output. Perhaps this over voltage is enough to cause a problem. I am going to seek out another 12 volt adaptor and see if that might work.
Thanks again,
Shawn
Update to R6400 Router problem.
I picked up another Netgear 12 VDC output adaptor and tried that with my router with no resolution. The second power adaptor also had a 15+VDC output.
Just measuring voltage output is not meanful. You have to test it under load. I have a little jig I can put in series with adapter output cable
which enables me to measure the voltage and current when plugged in and router powered up.. Also using a O'scope I can see how clean the out put current is. Some times theybecomes intermittent; like good for a while bad for a while >>> until it quits. Amber LED means CFE boot loader time which means it is waiting for a f/w. Like I mention earlier if you can ping the router, there is good chance tftp will work for you. Good luck.
