Daily DNS Errors (5G ZTE Router)

[KJW1996]

Hi,

I've been having daily and reoccurring DNS Errors with my ZTE 5G Router, I don't know what's even causing it, it was happening even on the default settings for DNS, and I'm aware that the Router needs too connect too the DNS Servers too translate the 1s and 0s, I figured maybe it was the servers themselves, so I decided to try the many DNS Servers for months and see which one stops the Errors (e.g. Google DNS, Cloudfaire, etc) but all Servers end up with the same Error that occurs either in the Afternoon 3pm or at Evening 8pm, the weird thing is the problem is fixed every time I restart the Router, so my theory is that it's not the Servers themselves, its the Router, or something Local, it's weird and I don't know how to resolve it. Any suggestions?

Kind regards,

Kyle Wright

Hi, have you ever managed to resolve it? I have exactly the same issue and Three support are clueless.

Hi Kyle,

I'm sorry to hear that you're running into these issues. I'll do my best to help.

I've never seen this specific issue reported so I don't think it's an overall issue across the network, so like you say, possibly something local or an issue with your router. Do you use Three for your mobile too? If it's happening at these consistent times it may be worth testing your router SIM in a phone, or other device, if available.

Has the issue been since day 1 of taking out the Broadband service, or did it seem to start more recently?

I'd also double check the Network Status Checker to see if we're aware of any network issues locally.

Let me know on the above, and I'll check how we best move this forwards for you.

Thanks,

Hi Jonathan,

I haven't had these issues Day One, it fairly recent from couple months now, and I do use Three Mobile Broadband too and I've never had any DNS Errors in my Smartphone (plus I use that on a daily basis), so too me it's definitely a Router issue. I Reset the Router many times and I still get the Errors, does ZTE have any noticeable issues with WI-FI Extenders? Or any limitations that cause it too stop working? Because I'm just theorising a lot of technical solutions, and none are working.

Kind regards,

Hi Kyle,

Thanks for the extra info, it certainly sounds like the router is the common factor here. We don't extensively test products that we don't supply, but one of my colleagues that works in device testing confirmed that we've used Eero mesh devices for some testing with no issues. I can't really give any other advice about the Wi-Fi extender question. 

There are threads from some other community users about intermittent drop outs, but they are at much more random times and no one has mentioned DNS errors to my knowledge, so I think that this is likely something different.

We have been rolling out new firmware for the ZTE as of mid February, would you say that it was approximately within the last 6 weeks this all started?

Hi Jonathan,

I did some extensive testing and Wi-Fi Extenders aren't the cause of the issue, speaking of which my ZTE Router apparently can't receive or check for any new updates, it can't even display the last time it was updated, it's just blank. The DNS issues have been occurring since around February, whether it was due to the update I don't know. Although the 'Auto-Update' is on, does the device interrupt the connection while its focusing on updating itself? Although I'm aware other members have experienced unique issues with their ZTE, mine is fairly a unique case.

Like usually a DNS Error is a Server Issue, but the Router can't seem too pinpoint why the Internet is Disconnected, even during the 'Diagnose' feature it gives everything a GREEN TICK, I don't know whether it's getting stressed out, bottlenecked, or anything, I'm going through theories and narrowing down solutions.

I can safely say that when I first got my Three Unlimited Home Broadband Package I never experienced these issues until early in the current Year, February at most. This technical issue is a very unique case for me, but the only thing I know is Disconnecting and Reconnecting it at the Home Menu (not Restarting) makes it instantly work. Weird...

Kind regards,

Hi Kyle,

Yeah it certainly does sound like quite a unique issue. The element where the software version and updates don't display is really odd as users have always been able to report the version on past issues.

I'd like to get that checked out further by one of our Tech teams to see if they can force an update, roll back, or diagnose if there's some sort of hardware issue. I'll send a private message that will direct you to some colleagues that can arrange this.

Thanks,
Jonathan

same, so not that unique, since yesterday it is just randomly constantly  frequently rejecting to resolve https sites. I guess I will return it and cancel the contract in that case, sorry
