Topic # 239373 14-Jul-2018 18:35

Good evening. I am hoping a networking guru can help me out with what is likely a simple problem.


 


I have just swapped to 2Degrees from MyRepublic UFB and am in the process of configuring the modem. When I set up a WAN, everything seems to go OK, and I get a good connection. Approx 5-10 mins later I start getting DNS errors which I can fix for 5-10 mins with a modem reset. 2Degrees requires PPoE, VLAN 10. What am I missing here? Any help very much appreciated.


 


(I am entering my username and password, I have just left these out for the pics)


 


Thanks

Try statically assigning DNS server IPs under "Advanced Setup > DNS" and see if that helps.

 

 

202.37.101.1

 

202.37.101.2

 

 

If it doesn't you may need to disable DNS proxy (and reboot router and all devices).

 

 

Did you choose to BYO modem?

Do you have one or more Apple devices on your network?

 

Can you still ping sites using an IP address while you have DNS failures? Netcomm devices including the NF4V and NF8AC were well renowned for suffering an issue where the local DNS proxy would crash requiring a restart of the router to fix. It was very rare to see the issue occur on a network without Apple devices, and it was pretty much guaranteed to happen fairly regularly on a network with Apple devices.

 

But.. This issue was resolved at least 18 months ago on both devices. I wouldn't expect MyRepublic to be running old firmware that doesn't have this fix applied.

Any idea if this router has the MAC table routing bug, that the NF4V has? Usual symptom is devices stop communicating when a second WIFI AP is added. As the NF4V can't handle MAC addresses moving between Ethernet and WIFI.

Yes to the DNS fix
Yes to the routing bug on the local lan

I still use the nf8ac for my vdsl but have 2 access points so no issues with the routing issue in that configuration.

Could you not try flashing netcomms stick firmware instead of using my republics?

Unsure. I do know both the NF8AC and NF4V were discontinued either late last year or early this year there won't be any major updates for them. The NF18ACV is the replacement and I've deployed a lot of these but haven't actually tested that for the issue as situations were I have external wireless always have the internal wireless disabled.

Wow, the level of knowledge on this forum never disappoints. Thanks everyone.

 

Interesting regarding the Apple issue. The modem is run directly into an Orbi mesh which has a Sonos, a PC, three Chromecasts, a bunch of Andriod devices and an iPad connected. I will disconnect the iPad and see if that changes anything. I will try pinging local sites next time the issue arises. I have run this router with MyRepublic for a couple years with the same devices with no issues though?

 

Last night, after I posted, we ran Netflix for a couple of hours with no issue. Interestingly, as soon as we stopped streaming the issue popped up. 

 

Yes, this is a BYOM, which I only elected to use because I am not a fan of creating e-waste for the sake of convenience. In this case, however, it seems the modem may have an issue that requires a replacement. I have ordered a new one and in the mean time will try Yitz's suggestion and investigate flashing it with newer firmware.

 

Thanks everyone, I just thought it was just a setting that I had missed.

Why are you even using the Netcomm if you have an Orbi system? It offers you zero advantages.

 

Are you running it as present so you're got double NAT or just as access points?

I'm probably about to humiliate myself here, but as I understand it, the Orbi is only a router, you need it connected to a modem.

You only need a modem for xDSL, not UFB. Just a router for UFB.

 

The NF8AC is a combined modem/router in one (like many modems are), so can be used for either.

You have UFB. You only need a router. The only case a modem is needed is for ADSL/VDSL.

 

The Orbi will connect directly to your ONT and connect to the Internet. You just need to enter your PPPoE details.

Have a look at PB Techs setup instructions for the Orbi

Oh my... what an idiot.

I thought as much when I bought it, but the instructions said otherwise. Guess I didn't read them correctly...

Thanks everyone, really appreciate the help.

Yes thanks mate. PBtech settings worked a treat, and now less wires and mess to worry about.

 

 

 

Thanks all.
