Re: Netgear Nighthawk X6 (R8000)'s power goes off incessantly

tishbite · ‎2016-11-04

My Netgear Nighthawk X6 (R8000)'s power goes off incessantly. We discovered that in the middle of demanding work, the network goes out, only to look at the signal lights of the Nighthawk, it is discovered that the indicator lights are either totally out or the power light shows amber.

I initially thought it were a power issue, but it was plugged also to a UPS just as the other router in the office. I waited again to have the Nighthawk to come up, and when it does after a couple of minutes, we (devices - one at a time) try to reconnect to the Nighthawk x6 (monitioring the now beaming lights).

The connection takes longer time, suddenly the once beaming light goes out totally leaving the power light to amber.

Heck, this is not comfortable. Could someone tell me know if you experience this also and how could it be solved.

10.0.0.1 is a problem in my opinion. It's caused when the r8000 is connected to another router AKA "Double Nat"

Have you tried it independently of the UPS?

Maybe it is playing up.

No, I have not really tried powering the Nighthawk independent of UPS especially to aviod power cut off, and by extension - network distruption. I'll give it a trial now. I will let you know how it goes. If it works without UPS, then that would be another problem to resume investigations; until then.

Thank you Michael.

Just trying to eliminate variables. As the issue seems to be power rather than anything easily pinned on the router, that is where I would look first.

Another possibility is that the transformer is playing up.

If the other router has the same transformer, then swapping them around would also be worth trying.

Do you mean the internal transformer of the devices? Wouldn't that break warranty for the devices. Please explain better just in case I don't understand that aspect of transformer swap.

One quick question please. I discovered that in error the other router (which provides internet to the Nighthawk for broadcast) was confirgured with same Default Gateway IP Address (192.168.1.1) as the Nighthawk. Although the Nighthawk automatically reconfigured its Default Gateway IP Address (10.0.0.1) since it was set to DHCP. Could this have any effect to its power instability? Just wondering.

The R8000 power adapter should be 12VDC @ 5amps Make sure you didn't switch it.

No. I didn't switch the power adapter. I still use the power adapter accompanied with the Nighthawk from the pack.

Just to add, the Nighthawk seems to stay on longer today after it was plugged independent of the UPS. I haven't returned it back to the UPS yet. It's off now as am out of the office. I would continue this test run on Monday God willing.

i would be glad to arm myself with as much troubleshooting solutions, as powering the Nighthawk independent of a UPS would harm user connectivity in cases of power fluctuations.

Thank you.

The transformer is the thing you plug into the wall to reduce the 120/240 volts from your mains into something that the router uses. It transforms mains voltage to the 12 volts for your device.

Transformers, sometimes confusingly dubbed power supplies, are known to go wrong. It is usually possible to replace them with something that puts out the same voltage and that can deliver the required current.

If you have two Netgear devices with the same current needs, then you can switch their transformers. This will show if one of these transformers is on the blink.

Kindly advice me with regards to the voltages as seen in the above images.

Thank you.

I will change one of the routers to 192.168.2.1 while the Nighthawk can retained it's reconfigured Address (192.168.1.1). I'll watch the results.

Thank you.

Still a double NAT

What do you advice? Had to stop by the office to try out some advice from here. Find the below pictures what I have done. Offer your kind advice so not run in same problem again even if maybe, that's not the reason for the previous issue.

The above image is the configuration from the router that provides internet to the Nighthawk. That's from one of it's Ethernet port to R8000's WAN port.

This above image is the configuration summary page of the Nighthawk.

Advice me please.

PS: Just to say that, the Nighthawk is still powered on and hasn't powered down on it's own for the last one hour.

tishbite · ‎2016-11-06

Sorry, had to change the DNS (10.109.2.97) on R8000 to LAN IP (192.168.20.20) on D-Link before the webpages began to work.

Hello.

I waited till this time to see if the challenge will return, thankfully, it has not.

I want to say thank you to all who contributed, and offering possible solutions.

God bless you all.
