R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Lastest update of R7800 introduces constant connection requests to servers that never gets replied.

Examples of such requests are:

 

Jan 20 20:30:00 dnsmasq[11677]: query[A] bolt.dropbox.com from 192.168.1.xxx
Jan 20 20:30:00 dnsmasq[11677]: forwarded bolt.dropbox.com to xxx.xxx.xxx.xxx

It would constantly send these requests until the internet either slows down, or stops working and results in webpages not found errors.

 

Standard requests should be as followed:

 

Jan 20 20:30:00 dnsmasq[11677]: query[A] bolt.dropbox.com from 192.168.1.xxx
Jan 20 20:30:00 dnsmasq[11677]: forwarded bolt.dropbox.com to xxx.xxx.xxx.xxx
Jan 20 20:30:00 dnsmasq[11677]: dnssec-query[DS] dropbox.com to xxx.xxx.xxx.xxx
Jan 20 20:30:00 dnsmasq[11677]: reply dropbox.com is no DS
Jan 20 20:30:00 dnsmasq[11677]: validation result is INSECURE
Jan 20 20:30:00 dnsmasq[11677]: reply bolt.dropbox.com is <CNAME>
Jan 20 20:30:00 dnsmasq[11677]: reply bolt.v.dropbox.com is xxx.xxx.xxx.xxx

These requests are taken from PiHole, and the latests update will reach the max concurrent request (150) in about 3 seconds.

 

I ended up having to downgrade back to V1.0.2.60 to fix this.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

I don't have these messages in my log.   Is there some extra log setting I need to set?

I simply use my ISPs DNS so have a very basic DNS setup.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Ditto. No problems since the upgrade. Delightfully error free log.

 

I didn't even have to factory reset, which is the first thing to try if you have post-flash problems.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Here also problems with the DNS since update to V1.0.2.62.

On page "Internet setup" Get Automatically from ISP works fine. It finds primary and secondary dns server.

When I want to use my own DNS servers things go wrong. Router loses internet connection.

My own dns points to my pihole which is at 192.168.1.2

DHCP in the router starts at 192.168.1.150 to 192.168.1.200.

 

I also went back to V1.0.2.60 which works fine.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Are your alternative dns servers in the range 192.168.1.x or for example 8.8.8.8 (google)?

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

I use as primary Google's DNS for first and second DNS entry. Third entry is CloudFlare (as backup). No issues here at all

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Tried disabling UPnP in the router firmware?

 

Was also getting extra traffic(or google warning about susicious traffic) and found out the .62 firmware has UPnP enabled by default.....tsk tsk tsk.

 

Unfortunately, I seem to not be allowed to create a thread warning R7800 users about this security flaw(it quickly gets deleted by moderators/NG personal). So I guess NG don't want R7800 users/the public- to know about this!

UPNP has been enabled by default on all the firmwares i have used .52 through 62. I always simply disable it.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

I didn't test this, but I wonder if it makes a difference, wether you use R7800 to make DNS request directly to your local ISP or you manually configure a online DNS server to use instead, like google or Open DNS or CloudFlare(1.1.1.1) etc.?  :-)

Your paranoia is showing. If Netgear really wanted to shut down talk about UPnP, which seems to be another reed herring, it would have squelched that message.

 

Many reports of "deleted" messages turn out to be "finger problems" on the part of users.

Yes. Again, no change.

How does that differ from what people have already reported here?

 

As some of us have said, manually setting for CloudFlare works fine.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Here is what I did:

Set router settings to factory default, then reboot the router.

Loaded the latest firmware V1.0.2.62 en followed the on screen instructions.

Manually did all settings again, not reading from backup file!

Receiving IP and dns settings from my provider.

LAN TCP/IP Setup are default, router IP = 192.168.1.1, subnet 255.255.255.0

Use Router as DHCP Server set the starting IP adress 192.168.1.150, ending IP adress 192.168.1.200

So far, so good. Everything works fine.

I can also change dns to 8.8.8.8 or 1.1.1.1 and that works fine to.

But as soon as I change the dns to 192.168.1.2, which is the static IP adress of my raspberry pi with Pihole, I loose internet connection.

These settings worked fine with previous firmware!

The raspberry pi is working fine to, when I give a static IP adress to my computer, gateway to 192.168.1.1 and set dns to 192.168.1.2 in my computer then the raspberry pi and pihole works fine, I can browse the internet whithout commercials.

But I don't like to give 5 phones, 3 tablets and 2 laptops a static IP and dns because they move around to school and work.

Somehow there is a difference between the dns of this new firmware and the previous ones. I read the dnsmasq has been updated to a more secure one, 2.78. Maybe there is a difference?

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

Hello - sorry to slightly deviate from the main topic however, I'm confused. My R7800 only shows FM v1.0.2.60 as the latest, not v1.0.2.62; same on NG's download section for R7800. Why and where can I find the new version?

Currently on v1.0.2.52 for stable 5GHz signal. V1.0.2.60 drops wifi for me on a 10-20min basis.

 

Thank you!

Awesome! Funny enough, I spotted the new version in an article about the release - one you pointed out - and not in the download section.

I received a pop-up alert when I logged into the router.

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

My feedback was mainly targeted as suggestions for the threadstarter to give a look at and secondly anyone else reading the thread, with issues after upgrading to .62 firmware! ;-)

 

I am new owner of the R7800(only used couple a weeks), and ran into some early issues and wanted to see what other users reported in the NG forums! ;-)

 

I also assume(when I generally give replies)that people reading are not all "network experts", so I provide feedback using less "techy wordings"(if that is even correct english? ;-P ).

 

But as I reported in my own thread(no it's still in here, just locked away by NG....was available in the forums for about 10 minutes and even got 1 reply from another user, before getting removed ;-) ). I received warnings from google's search network, when I did a search on keywords....and long story short, it turned out to be an issue with my R7800 router(problem dissapeared when connectiong directly to my ISP modem). Disabling UPnP stopped the google network search-stop warnings.

 

Concearning DNS server....most "home family users" still don't know what this is and just leaves it at default setting. Which means the DNS traffic goes through the router. And if you live in Europe(like me) this is most likely also the best way to get the fastest DNS server you will get(open dns, cloudflare etc. are USA based, and thus typically not the fastest "signal path" when living on the other side of earth ;-) ).

 

Btw. do you also remember to configure DNS on all your wifi devices in the house(phones/tablets etc.)? Else they will all go through the router as well.

 

While waiting for answers from NG, I also noticed the .62 firmware was suddenly away on the product page.....I figured it was probably pulled......or perhaps in for a quick mod. update and re-released, hoping nobody noticed(how's that for being paranoid? ;-P ).

 

Ps: **bleep** even my replies are now being rejected it seems....guess I'm not NG compatible?  ;-)

You might do well to spend a bit of time working out how to use this website. I see no evidence that anyone is removing your messages, but you do seem to have a problem posting them.

 

As to the firmware being pulled, no, you just need to know where to look. (See above.)

Re: R7800 Latest Firmware Issue - DO NOT UPDATE TO V1.0.2.62

I 100% have the same problem and can reproduce easily.  The issue seems to be pointing the Router's DNS server to an internal/local IP address (ie, for pihole).  I can use a public DNS server without issue, or leave it as getting from ISP.

 

Once updating to internal IP i can see requests going through to pihole, and the first couple of pages will load, but after that all page requests get DNS_PROBE_FINISHED_NO_INTERNET.  Requests become really slow during this time as well, which makes sense based on OPs log if it is contually trying to make requests.

 

Setting back to 8.8.8.8 everything works fine again, no need to bounce router after applying setting.  I had this same set up (internal DNS server IP) on previous firmware for over a year with no problem.
