I have occasional DNS errors and reloading the page resolves it. Here is the link for details from other people who had same issue but no resolution was provided. Any ideas? https://community.netgear.com/t5/Orbi-AX/Intermittent-DNS-Errors-and-WiFi-Issues/m-p/1950768 Thanks,

I've had this firmware since the weekend and I haven't had any DNS Issues pop up on my end. I do change my DNS Servers to OpenDNS through the Router GUI and have IPv6 Enabled (also using OpenDNS).

Your Arris modem has a router and built in router already. This can cause some problems. This would be a double NAT (two router) 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 Orbi 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 Orbi router gets from the modem. Then you can use the Orbi router in Router mode.3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop ATT Modems:https://www.f0il.com/how-to-arris-bgw210-700-modem-router-with-netgear-xr500-router/https://community.netgear.com/t5/Orbi/How-do-I-setup-bridge-mode-in-the-ARRIS-BGW210-700/m-p/1875994/highlight/true#M84982ATT Dumb Swiith Method:https://community.netgear.com/t5/Orbi-AX/Orbi-AX-6000-and-AT-amp-T-fiber-gateway-issue/m-p/1890125/highlight/true#M2756eliea wrote:NG firmeware version is V3.2.16.6_1.4.4 ISP is AT&T with 1 Gbps connectionManufacturer ARRISModel Number BGW210-700 ONT Alcatel-Lucent G-010G-A

You'll need to keep in contact with NG support. Keep on them about this.

100% agree - NG needs to get their act together on this. On my part - I am retunring my NG, not worth my time and efforts anymore. After wasting several hours on the phone with their support just to upgrade firmware with no benefit, I pulled the plug. I have switched to my ISP's (Optimum) mesh network solution and it works comparably well without the annoyances of NG denying to serve web pages at random.

  1. Current firmware installed: V3.2.16.6_1.4.4
  2. ISP: Comcast Xfinity
  3. modem brand/model: Arris T25
  4. I tried with Chrome, Safari and Microsoft edge. Saw same behavior.
  5. I do not see the same behavior when directly connected to modem. In addition, I did not see this issue with my other Orbi router (RBK53).

    Has a factory reset and setup from scratch and power OFF the ISP modem for 1 minute then back on been performed?
    What happens if you change to using manual DNS on the RBR from automatic to say:
    Level 3: 4.2.2.1
    Level 3: 4.2.2.2
    Level 3: 4.2.2.4
    Level 3: 4.2.2.5
    or
    OpenDNS: 208.67.220.123
    OpenDNS: 208.67.220.220
    OpenDNS: 208.67.220.222
    
    I have now loaded my system with v6 FW, dirty update and no reset. I'll be putting mine online later this evening when all house occupants go to bed. I don't have the same modem though so results may differ.

I am having the same issue and spent tons of time with support with no luck.
Before the newer version a support guy acknowledged it is a firmware issue and asked me to change ORBI to AP mode and the issue went away. Definitely with AP mode lots of functionality won’t be available including armor (armor is free for a year with Costco version). The guy promised that the issue will be solved after the firmware upgrade of Mid August.

I reverted back the AP mode to router mode and the issue is worst then before, tried all what you guys mentioned and nothing worked except AP mode. Spent again lots of time on the phone with support and no luck at all, and they never acknowledged after the latest firmware that this is a know issue.

Not sure what else can be done.

  Only solution worked for me was setting static DNS in PC/device. I also spent time with NG support with no resolution. Hopefully, they will fix this in next firmware.

  Out of curiosity, who is your ISP? I have Comcast and use OpenDNS as my DNS Servers, and I haven't had a single DNS Error and I have the same system as you, RBK753S from Costco with Armor Enabled. I can't imagine it being purely a firmware issue if I'm not having the same issues, it must be a combination of the DNS and Firmware.

    I have same setup as you with Comcast. Tried these DNS as well. Swapped even with different router from Costco and still issue. Worked with NG and no resolution.
