Ongoing DNS errors on connection

[andyh12345]

I have a significant issue with my broadband. I am rarely able to access web pages, with each giving DNS_PROBE_STARTED errors followed by DNS_PROBE_FINISHED_BAD_CONFIG. This occurs on wired and wireless connections. 

If I reboot the router it is usually OK for 15-20 minutes before it stops again. 

In the router logs I see numerous messages of the format

2022-08-15 13:17:46 [Informational][Debug-Log] static:DNS service of wan3 is abnormal
2022-08-15 13:18:06 [Informational][Debug-Log] static:DNS service of wan3 is recovered

I tried phoning Talk Talk support earlier, but they were utterly useless - they seemed more concerned that I had a disconnected Powerline adaptor than dealing with the actual problem, and of course when the router was rebooted they seemed to think it was all sorted. 

Is there any way to get assistance from someone with actual technical knowledge?

Hi Andy

Thanks for your reply.

Is this a date for your FTTP installation?

[andyh12345]

Apologies for the delay in replying, I as on holiday last week. 

The new router arrived and I connected it before I went away. It seems to be working better than before, however I did see the connection speed drop significantly after it had been connected for a few days. Now I'm back from holiday I'll continue to monitor it and see how it performs. 

However, this may be irrelevant as I have also received notification that OpenReach will be installing fibre to the premises in a fortnights time.

Hi Andy

Have you received the replacement router?

Thanks

Hi Andy

The router is on its way, please allow 24-48hrs for this to arrive.

Let us know how the connection compares with this router.

Thanks

Yes please, trying an alternative router might be a good option

Hi Andy

The issue with DNS was reported on the Sagemcom hub and that's why I was checking the firmware.

Would you like me to send a replacement router for testing?

[andyh12345]

No, just the one that's connected. 

Current status is that after a reboot last night it has stayed up overnight, but experience suggests it'll go down again at some point today.

Hi Andy

Thank you. I can see a Huawei WIFI hub connected at the moment. Do you have the Sagemcom WIFI hub too?

Hi Andy

Please can you add the serial number from the back of your router to the Private Notes section of your Community Profile.

Thanks

The broadband was working last night, but by this morning had the same problem as before.

Morning,

Please let us know if this does happen again and we can investigate this further for you.

Thanks

I have powered it down for approx 40 minutes before powering back on. It's working now, but the usual patter will be that it fails soon. I will let you know how this gets on.

Hi andyh12345,

Thanks for updating your profile. Could you switch your router off and leave it off for at least 30 minutes then switch back on and retest. Please let us know how you get on
