New - R7900P/R7960P/R8000P Firmware Version 1.4.3.88 Released

Same problem.  Started about 6-8 weeks ago.  Firmware is up-to-date, rebooted router.  No joy.  Nighthawk R7900P  Firmware Version
V1.4.3.88_1.3.50

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Did you try a factory reset and setup from scratch then enable IPv6?

I have not done a factory reset since this issue started.  Only rebooted the router then unplugged the modem and router & let them restart.  I will find a time and give factory reset at try.

Please enable IPv6 as well after you get to the home page after you walk thru the setup wizard.

Ok folks, I finally got back to working tis issue.  Before trying a full factory reset, I enabled IPv6, rebooted the router and the devices.  That appears to have corrected the problem.  I have not gotten a DNS error since.  Thanks for the assistance.  I'll update if it shows up again.

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

All,

I have read several posts about DNS not resolving and am suffereing the same issue and it is now impeding my ability to work from home. I can tell you the following:

1. I used a managed switch and wireshark to monitor the traffic between the R8000 router and my cable modem
2. I also used a seperate wireshark to monitor traffic between my laptop to the R8000 router
3. I can see my l laptop send a DNS request to the router and the router forwarding the request to the specificed DNS service on the public side of the network.  I also note the UDP source port on the public DNS request so I can then match it to my laptop request given the NAT table changes this.
4. I can see the DNS service send a valid response back to the R8000 router with a destination address of my public IP address and the approprate destination port with matches the port used for the routers DNS request.

So far, so good, everything is as expected.  Now it gets wired:

1. The R8000 sends my laptop a DNS response with a "REFUSED" response code.  Note, the DNS response from the DNS service did not have a REFUSED response code and in fact has the resolved address in it.
2. The R8000 also sends the DNS service an ICMP message "Destination Port Unreachable".  Funny thing is it I can see it is the correct desination port.

Clearly, this is not the correct behavior.  It has nothing to do with my ISP or anything else like it.

Also, when I filter the trace on the public-side for ICMP Desination Port Unreachable messages, I have a lot of them and they are all comming from the R8000 and they are all assocated with DNS server responses.

I have the traces if it helps.  I would like to know when there will be software to fix this, what work arounds are available, and if there is an older firmware version the WILL WORK.

Try enabling IPv6 on the router while v.88 is loaded. 

It is a Motorola MB8611 and I will try IPv6 this afternoon

👍

About a month after enabling IPv6 and no longer getting the DNS Probe error, I started getting multiple daily random internet connection drops, all devices.  I plan to roll back the firmware to .68.  There seems to be a bunch of problems with the latest software releases and Netgear shows no sign of acknowledgement or fixing them.  I suspect at this point that they are just joining the software obsolescence club and purposely trying to annoy customers into buying new hardware with bug filled updates.

So how are you determining that "multiple daily random internet connection drops" is a router or FW issue? 

Is the Internet LED on your router showing AMBER when this happens? How about the wifi LEDs? 

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Did you try and disable IPv6 to see if the behavior changed any? 

Has a factory reset and setup from scratch been performed since last FW update?

What CAT# lan cable are you using between the ISP modem, router and wired devices? CAT6 is recommended. 

Would need more information and troubleshooting before blaming the router or FW.

Charter/Spectrum Technicolor E31T2V1 / DOCSIS 3.1 eMTA

Determined internet drops by observing computers, phones, Roku, Amazon smart devices all having connection disruptions simultaneously throughout the day for the past 2+ weeks, 3-5 times per day.  They self resolve within a minute or two.  If I reboot the router they appear to occur less frequently for about a day, 1-3 times.

I am making assumptions, but I never had any connections problems until I installed the latest firmware.

I have not checked the internet LED during a drop, but I will next opportunity.

I have not disabled IPv6 since enabling it fixed the constant DNS probe errors.

Using the yellow CAT-5E cable that came with the router, R7900P Nighthawk X6S.

Speed Test using Nighthawk App on iPhone: 459Mb Down, 23.3Mb Up.

From Win10 using Brave browser over wireless from Speedtest.net: 16.82Mb down, 22.91Mb Up

Ran these speed tests about 2pm while both wife & I were working from the house.

I have not done a factory reset since these issues started.  If I do, should I save the current configuration and reload it or key it all back in manually like from the box new?  Does factory reset roll back the firmware to what it shipped with or just clear configurations?

I would make sure your modem and ISP services are not adding to this problem. Sometimes ISP services can be problematic. Ask the ISP to check there logs and signal up to the modem for any issues seen around the same time frame that you notice that you can't get services thru the router.

I have not done a factory reset since these issues started.  If I do, should I save the current configuration and reload it or key it all back in manually like from the box new?  Make a backup config first however after doing a reset, I recommend setting up from scratch initially and see how things go. I would avoid enabling Access Controls, Armor, Parental Controls, QoS and Traffic Meter. See how it goes using this configuration. If not, you can reload the saved backup from file later on.

Does factory reset roll back the firmware to what it shipped with or just clear configurations? NO. Just clears any user configurations is all. 

Does the router feel extra warm to the touch or normally warm? Might put a laptop fan under the router for additional cooling.

Wise move.

Always a good idea to wait for the dust to settle.

But do remember that you can roll back to older versions if you hit problems with new firmware.

Any progress on this?
