Re: Intermittent DNS Errors and WiFi Issues

So glad I've read this thread. Thankfully I can correct my mistake now. Received my 853 system yesterday and it's going straight back. Not even opening the box, straight back. I'm not going to buy a stand alone router to fix built in problems of the Orbi nor try the work arounds to fix what shouldn't be a problem. Not even going to see if my hardware is good, straight back. What blows my mind more than anything is the lack of NG involvement here. I've used many NG products over the years and have been generally pleased. I'm not going to put up with inherent bugs right out of the box though. Return.

Re: Intermittent DNS Errors and WiFi Issues

Thats your choice to not try your system. Not everyone sees this problem. Mines working well. Even on recent FW.

NG IS aware of this problem for those that are effected by it. 

 

Good Luck.

Re: Intermittent DNS Errors and WiFi Issues

With the latest firmware and using the 6to4 Tunnel option under the router admin settings, I had no issues.

 

However, Google Search started popping up a "6to4 Tunnel detected - This is being deprecated warning with a forced captcha puzzle to complete each time.

 

"We have detected you are using a 6to4 tunnel. 6to4 is deprecated and will be shutdown shortly."

 

My ISP doesn't support direct IP6 connections, so I disabled the 6to4 Tunnel to get rid of the Google deprecation warning and went back to an IP4 connection.

 

As soon as doing so, DNS errors started appearing again. So it's clearly only IP4 connections affected (or affected the most).

 

If you can't do IP6 with your ISP, currently I can not recommend this router Mesh. They won't bother fix it.

Re: Intermittent DNS Errors and WiFi Issues

IPv6 6to4 isn't required to be suported by the ISP to use 6to4 on the router. I've used 6to4 with mine and it works. My ISP doesn't support any native IPv6.

Re: Intermittent DNS Errors and WiFi Issues

@FURRYe38 Same, it was what I was originally using to fix this issue as well.

 

The search engine Google.com, started warning me about using it, if using the Firefox web-browser with DNS over HTTPS (other web-browsers don't seem to show the warning message and required captcha). It's a security risk or some issue with using the 6to4 Tunnel, that it has been Deprecated back in 2015. Google now plans to remove all support for it.

 

I forgot to take a screenshot of it, but have found one from someone else, see attached. You have to complete that every time you want to use Google search, if using 6to4 Tunnel, with Firefox and DNS over HTTPS. It doesn't appear to be safe or secure to use? It was deprecated due to possible hijacking and spoofing across it.

Interesting. Well I don't use Google so I presume other seach engines may work differently. 

Wonder what router mfrs are doing with this. I try and inquire about this and see.

Good to hear so far. 

 

To ALL Orbi AX 7 series users having issues with DNS errors, please contact @Christian_R if your interested in testing this beta version of FW for this DNS issue on your 7 series Orbi. 

NG will hopefully be getting the 8 series updated soon as well. No information on this yet.

Re: Intermittent DNS Errors and WiFi Issues

Do you still have IPv6 6to4 enabled or disabled? Good test on this beta would be no to use 6to4 DNS and use Automatic DNS options on the RBR to see if something appears or not.

Re: Intermittent DNS Errors and WiFi Issues

I am looking forward to the release of this update for the RBR850 ans RBS850. 

 

My problem is different from most users. I have a router (peplink Balance 20X) between my Modem (in Bridge mode) and my Orbi RBR850. 

 

When I use the Orbi in Router mode, most things works (with occasionally the connection between the RBR850 and one of the satellite that goes down). 

 

When I use the Orb in AP mode, the peplink does the routing and everything seems to work fine for a few hours to a few days. Then suddenly all my IoT devices cant resolve some DNS queries (Google Nest Hubs, Homepod Mini, Samsung Smart TVs, Philips Hue hub, PlayStation, ...). 

Macs, iPads and iPhones works fine (except League of Legends, and a few more games...). And some device have strange problems. For example I can update the playstation but I cannot connect to the PSN. 

 

If I switch back the Orbi in Router mode, everything start to work fine again, but I have a double NAT. I think the Orbi Router caches and/or intercepts some DNS queries and there is a bug, EVEN IN AP MODE !!

 

I hope this update will finally fix the problem.

Re: Intermittent DNS Errors and WiFi Issues

Does this Pepink router have a DMZ? IF so, you can use the DMZ on this router for the Orbi in router mode...

Orbi in AP mode would not be routing or modifying any DNS. AP Mode is just data pass thru.

Re: Intermittent DNS Errors and WiFi Issues

That sounds like some good news - after more than a year - if the beta firmware for the 7 series fixes the DNS Issue. Does make you wonder why isn't there any beta firmware for the 8 series. And why wouldn't Netgear just post the beta firmware, or why doesn't the moderator make a post in this thread.

 

I am not sure if my Orbi AX will ever be used a router going forward. The capabilities of the Orbi AX are limited and the DNS / DHCP mechanism is also working a bit different compared to Asus. I am getting a really good user experience with the Orbi AX as expensive access point and my old Asus router doing the routing work.

Same here.  After running the Orbi as AP and Asus for routing duties, I am never going back to using the Orbi standalone again.  While it does great for wireless duty, it's routing and controls totally s*ck compared to the Asus.  Next upgrade will be totally Netgear free for me.

Wait 6 months to a full year, if it actually exists.      How easy it is to claim access to a beta and then say the NDA prevents showing screenshot proof lest legal issues.

 

If it's true, now I'll be angry how long it takes to come to consumers.    If it's false, thanks for kicking the hornets nest of customer dissatisfaction.

Re: Intermittent DNS Errors and WiFi Issues

I have updated my router and two satellites to the beta firmware, v3.2.19.4. I reset the network connections and manually rebooted all three devices (router, satellite, satellite in that order). After releasing and renewing device IP settings on a device I knew had issues, I (so far) have not had issues with that device (after trying to get it to break for about 30 seconds, I could not).

 

I will keep the community updated, but I am hopeful.Thank you, @Christian_R for providing the beta firmware.

P.S. The config of the dnsmasq run line does not appear to be changed, so I'm not sure what they changed:

dnsmasq -h -n -c 0 -N -i br* -r /tmp/dns/resolv.conf -u root

 

DNSBench shows better performance than outside router for DNS lookups except for 'cached' - I am assuming that dnsmasq is still providing no caching capability on the router.  I've structured my layout to point the Orbi at the DMZ router DNS and utilize it for cached entries - at 7 ms delay, it's probably not going to be noticeable.  We'll see when I boot up the games later today.
