Strange DNS failures

mitchgixer6 — Thu, 25 Aug 2022 11:09:20 GMT

Hi all

I have been having issues with my connection recently, mainly slower speeds (still hitting 30mbs) and disconnects.

I have just spent 40 minutes on chat with the tech team trying to nail it down, but no errors with the line showing, suggested it may be wiring in my house but nothing here has recently changed.

I was just looking at my router setting and noticed some strange behaviur in the logs. Lots of DNS name resolution failures during the night when there would be no acces on my connection.

Anyone have a clue whats going on or if this could be the cause of my instability?

Thanks

Hi mitchgixer6,

Can you please update your community profile to include your:

Telephone number
Alternative contact number

We'll then look into this further. Please do not post this information on this thread. Once you've updated your profile please post in your topic to confirm it's updated.

A new router is on the way so hardware issues can be ruled out.

Hi Karl

That's great news, thank you so much for sorting that out.

Hopefully that helps with the problem.

Cheers

Hi again

So i've installed the new router this morning. Nothing has changed......

Still getting lower than expected speeds, and within 30s of the router establishing itself there are logs of DNS name resolution failures. I've copied an pasted them below.

Would appreciate any other advice on anything else I could try.

Thanks

Hi mitchgixer6,

Are you experiencing any problems with your telephone service, any noise on the line?

Hi Chris

We don't use the landline telephone at all, there is nothing for that plugged into the master socket.

Hello,

Ok thanks. Does the main socket have a test socket? If it does then would it be possible to connect the microfilter, router and phone at the test socket so we can re-run the line test again please? Also just to advise, it can take up to 48hrs for DLM to start making changes to the sync speed if the connection remains stable once the router has been swapped over.

Thanks

I don't seem to have a test socket. I have a NET5c base plate with a Mk4 filter attached. I have no way of connecting the DSL cable with the faceplate removed.

The low speed is annoying, but my main question was wether the DNS name failures were anything to worry about.

I think the DNS errors are probably just short interruptions to your internet connection. I can't see the real time data for today yet so can't see if the connection was interrupted at the time that you experienced the DNS errors but I can see that there were some unavailable seconds yesterday

So I'm still getting poor connection speeds. I ran another diagnostic on the TalkTalk site today and it still show my line seems OK, but aknowledges my speed is slow and flags that as an issue.

Where do we go from here.....?

We would need to do some further checks and then arrange an engineer visit if required

Do you just have the one telephone socket in your home?

Chris

Re: Strange DNS failures

mitchgixer6 — Wed, 07 Sep 2022 06:56:36 GMT

OK. Yes we only have the one socket

Re: Strange DNS failures

Chris-TalkTalk — Wed, 07 Sep 2022 07:18:21 GMT

Thanks. Could you connect the router to the test socket with a micro-filter and leave it there for at least 48 hours. If there's then no improvement in speed/stability then the next step will be to arrange an engineer visit

Re: Strange DNS failures

mitchgixer6 — Wed, 07 Sep 2022 07:20:51 GMT

OK, I will do that this morning

Thanks

OK, thank you 🙂

Re: Strange DNS failures

mitchgixer6 — Fri, 09 Sep 2022 07:23:01 GMT

OK, so that's been my router plugged into the test port with a filter for about 47 hours. Still no improvement in my speeds.....

Re: Strange DNS failures

Chris-TalkTalk — Fri, 09 Sep 2022 07:30:10 GMT

OK, thanks for trying that. If you'd like us to arrange an engineer visit please let us know and we'll confirm some details
