DNS issue?

Stoeger — Fri, 12 Sep 2025 16:15:59 GMT

Had a powercut and now my router won’t connect to the internet no matter how many times I restart/reset it. Just keeps saying DNS issue?

@Stoeger What screen does it make that statement on? What laptop/tower are you using, and which browser?

Windows PC, firefox browser

Are you able to navigate to the router's web interface using your Firefox ?

OK. I assume you are currently posting from a phone/tablet over a mobile network? Can you post a screenshot of what you see on on the PC, please?

@outcast I know we'll have to wait 12-15 hours before we see the picture, but... 😉

Yes. What do you need a screen shot of?
Internet status says it’s connected, it just keeps saying the DNS server isn’t responding.

The actual 'DNS server not responding' message, please.

@Stoeger - I'll let @jab1 ask you questions, and I'll quietly watch, so we don't overlap at cross-purposes.

Cheers, @outcast . But an answer to your valid question would also help.

“Your computer appears to be correctly configured but the device or resource (DNS) server is not responding”
I’ve tried setting the DNS from auto to google and openDns but still no luck.

What DNS servers are configured on your non-responding device? This may need deeper investigation.

Re: DNS issue?

Stoeger — Fri, 12 Sep 2025 18:02:22 GMT

At present it’s set back to auto
Primary DNS: 212.159.13.49
Secondary DNS: 212.159.6.9

Re: DNS issue?

jab1 — Fri, 12 Sep 2025 18:04:34 GMT

And it says they are not responding?

@outcast - your thoughts - please.

Re: DNS issue?

Stoeger — Fri, 12 Sep 2025 18:06:07 GMT

No matter which DNS I still have no internet and get the same message.

Re: DNS issue?

jab1 — Fri, 12 Sep 2025 18:12:24 GMT

So, you have tried THE google and Cloudflare DNS's as well ? Bit off my pay scale, but it sounds like your machine may have a problem.

Hopefully, with that information, @outcast may be able to offer suggestions.

Re: DNS issue?

Stoeger — Fri, 12 Sep 2025 18:16:46 GMT

Yes tried all 3. Wondering if the powercut damaged something internal.

@jab1 - you could try seeing whether the DSL line stats look OK (assuming FTTC), and perhaps getting the connection log, as the process of doing that will answer several questions.

Re: DNS issue?

jab1 — Fri, 12 Sep 2025 18:23:43 GMT

@outcast I don't know if the line stats would help, but the .csv of the error log may. If it can't resolve any DNS servers, where do we go from there - as I said, this is a bit outside my knowledge base, but I'm still willing to learn.

@Stoeger Can you attach your exported error log please?

I'd like to see evidence of the broadband really being connected with a working PPPoE session,

as it is very unlikely that everything is OK with the exception of the router's DNS.

Scrolling back through multiple “timed out after none of the configured DNS servers responded”
I’ve tried both Wifi and ethernet but still nothing.
Plusnet said they’ll ring me tomorrow as they’ve been unable to refresh my connection from their end. But said the line from the network to my place is still working.
