Hi

Moved my NBN 50/20 (FTTN) to Leaptel from Superloop about a month ago and for the past two weeks+ have been getting the following error for every website I try to access.

"This site can’t be reached
www.google.com’s DNS address could not be found. Diagnosing the problem.
DNS_PROBE_POSSIBLE"

It happens on all devices connected to the wifi- and randomly happens maybe once or twice an hour for 5-10 mins.
I have contacted them and changed the DNS server (8.8.8.8, 8.8.4.4 and 1.1.1.1 etc), reset the modem and set up everything again, activated SRA, Flushed the DNS Cache, network adapters are up to date. Router is Archer VR600

They don't seem to know what's going on as nothing is showing up on their end. I didn't have this issue with Superloop once in the 6 months I was with them.

Is my only option to just switch out or does anyone know a fix?

    Cheap ISPs are cheap :/

      No they are not, they are just cheaper…

      Leaptel from my experience over 5 years they are fantastic. Always reliable speeds and the one time I had an issue, the wait on tech support was short and the guy actually knew what he was doing and not just reading a pdf.

    Have you tried doing a tracert in command line to see at which point it fails?

    If the trace route fails when still in your network, then you know it's something to do with your set up.

    If it goes to Leaptel and then fails, then it's something on their end, you can pass on the last server details to them, and let them escalate it further up the chain as the front line tech wouldn't be able to resolve this.

    try setting up 8.8.8.8 at your PC's network adapter and check whether it solves the issues

    • lurker69 on 07/11/2022 - 05:30

      have already done this and on the router aswell

      • bazingaa on 07/11/2022 - 11:42

        that's weird, try chatting with customer support, they are in Aus and helpful. I don't have any issues with the same package on FTTC, even full IPv6 is working for me (need to enable IPv6 on control panel).

    Try superloop

  • websterp on 07/11/2022 - 07:43

    Do you have any firewalls or content filtering enabled ? If you don't use a pihole or any other dedicated device then disable any site security and content filtering settings on your router and see if you still get this error.

    changed the DNS server (8.8.8.8, 8.8.4.4 and 1.1.1.1 etc)

    If this didn't solve the issue, then I'd be moving ISP. It is possibly some weird routing problem.

  • djsweet on 07/11/2022 - 09:39

    I’ve heard (although never observed myself) that some ISPs reroute known dns addresses to their own dns servers. You could try a less well known DNS service and see if that fixes the issue. Probably a long shot, but who knows!

  • bhakharvadi on 08/11/2022 - 02:35

    Try turning off CGNAT, I think leaptel uses that and it could be worth giving a shot.

  • MarketingLeaptelRep @ Leaptel on 09/11/2022 - 21:32

    If you haven't already, please contact support. It sounds like the router is caching DNS badly after the switch and it might be trying to use the old RSP's DNS and ignoring the settings you've set.

    You probably want to factory reset it, but speak to support. They'll run you through a few things (its why they exist!).

    • MarketingLeaptelRep @ Leaptel on 10/11/2022 - 09:22

      I just re-read your post and said you've already been speaking to support. If you can, send me a private message with your account details and I'll look into your situation further.

      We don't have DNS or routing issues so I am surprised you are having this problem.

    Hi, is your issue resolved as I am currently with Superloop and Leaptel is one of my considerations to move to, after reading this I am a bit hesitant to go ahead.
