Nighthawk X6 R8000 blocking

Question

I found pinpointed the problem but I don't know how to fix it.

My router is blocking apps and sites, specifically my Stamps app and Word and OneDrive by MS AutoDesk Fusion360.
These programs will work for a time but then stop and not allow sight in. Once I change the channel it will work again for a time and then block the site.
I have no blocked sites or child restrictions and such. I have just 2 channels, 2.4 and 5.0. I have tried to reset the router etc. Trouble shooting with Stamps I was able to login with a mobil hotspot which then let me to cycling the channels of my router.

Reinstalled Windows 11 also but no help.

Also I have disabled McAfee Firewall and anti virus and checked Windows defender.

Can anyone help. I may need to buy a new router?

Your ISP Modem already has a built in router and wifi.&nbsp;This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple of options,1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routershttps://kb.netgear.com/24086/How-do-I-set-up-a-default-DMZ-server-on-my-Nighthawk-router3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router. https://kb.netgear.com/20927/How-do-I-change-my-NETGEAR-router-to-AP-modehttps://kb.netgear.com/000061927/What-is-the-difference-between-router-mode-and-AP-mode

Try option #2 first...

What makes you think this is a router issue? That error looks more like something in Windows than a router error.

What firmware version do you have on the R8000 device? A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.It might also help if you told people what the modem is in front of this router, if there is one. The make and model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.

Thank you,&nbsp;Very good suggestions, I will try to clarify my trouble shooting.I am using&nbsp;3/30/22 - Firmware update 1.0.4.84 for R8000&nbsp; verified with app version 2.26.0.2884 on my Android phoneI think it is a router issue as I was directed by Stamps support to use a Mobil&nbsp;hotspot on my phone and the program worked fine, so Stamps support pass it on and said, not our problem.I am using Windows 11 Home Version 22H2 64 bit on an 11th Gen Intel&nbsp;processor.Authentication settings are set to Off, no metered connections, Automatic IP assignment, I have no VPN and turned off 'Allow VPN over metered networks and while roaming, Windows Firewall and network protection is turned off at this time.The setting in Windows to block potentially unwanted app downloads is turned off at this time.&nbsp; Secure boot is on.I'm drawing at straws here trying to figure this out.I have Xfinity and modem that is located about 600 hundred feet from the NightHawk router.&nbsp; (My home is this distance from the street and Xfinity wanted 50,000.00 USD to bring the router and modem to my home, I'M NOT KIDDING) so I use a pair of extenders in a Cat 6E burial cable and get a pretty consistent&nbsp;75Mbps on the 5G channel down from the 100 or so I get from the street.So for years it has worked with the NightHawk setup just like this.&nbsp; I have had a couple times I replaced it after lightning strikes etc but generally it has work in this setup.&nbsp;&nbsp;I am not a network expert and really don't have any more ideas on what to do to fix it.&nbsp;Thanks again,Richard

&nbsp;

Is the network set to Public or Private?
&nbsp;
I have Xfinity and modem that is located about 600 hundred feet from the NightHawk router.&nbsp; 
We still don't know what that modem is.
&nbsp;
You seem to be on the edge of what you can get with LAN technology. Atypical networks like that are hard to diagnose.

First of all, again, thank you.So the modem is Arris Model TG1682G owned by Xfinity.&nbsp; It is near the street as required by Xfinity, I then run the Cat 6 burial cable 600' or so thru extenders, all surge protected, to the house and attach to the Netgear router.&nbsp;It has worked for years.&nbsp;Some struggles with speed, the extenders handle about 100 and if Xfinity thinks they are giving me more by bumping it up to 200 my end at the house suffers.&nbsp; &nbsp;There are other comments but in the end I saved the 50,000.00 dollars and have very very satisfactory internet a the home. (most of the time)&nbsp;So, what I don't understand is now the Stamps program requires me to cycle the channels.&nbsp; It will work for a time and then I get the error.&nbsp; I cycle and it works again for a time.&nbsp; Even Office 365 will do this checking my email.&nbsp; It just hangs up and I notice I'm not getting email, cycle the channel and boom, here comes the email.&nbsp;Signed,Perplexed!&nbsp;&nbsp;
