Using ISP detected DNS or custom DNS? 

Is IPv6 enabled on the RBR? 

What brand and model# ISP modem or ONT is the RBR connected too? 

 

If you updated and haven't done a reset and setup from scratch, should be done to check this.

    Hi Furrye38

     

    I've tried both ISP DNS and custom (8.8.8.8 etc) and I'm now using pihole for DNS and DHCP. None of my DNS or DHCP changes impact the issue on v15. 

     

    IPv6 is disabled.

     

    Nokia Hyperfibre 2000, model: XS-2500WX-A that my fibre telco (Chrous) refers to as an ONT-110. Details here: https://www.chorus.co.nz/help/ont/hyperfibre-type-110. I have 2000up/2000down and for the most part its reliably at these speeds from the speedtests on the Orbi app and Web, which is remarkable in itself.

     

    MTU is 1500 as per ISP/telco requirements for Hyperfibre. VLAN tag group ID 10 as per their reqs.

     

    BTW the speedtests pass fine from the Orbi App and WebUI on v15 and also when the MackBook is connected to a satellite running v15. It's only an issue on router ethernet ports on v15, which is most odd. Sadly I can't wire my LG 4k TV to a satellite ethernet and it's not great on WiFi otherwise I would have lived with v15. I'm not bothered about the MacBook not working on the router ethernet on v15 and this was purely to prove a point - I mostly use the MacBook off a satellite in the study or roam on WiFi. I am using Cat6e patches and structured cabling.

     

    I have a load of ethernet connected Pis into a switch on the router (some direct to router ports) and these don't seem to show any issues on v15 but they are just ticking over running stuff like pihole, HASS, Docker stuff, so I've not been able to confirm if Pi ethernet on v15 is unreliable as I haven't got an ookla Speedtest app on them to run up to the limits, but I will see if this is available and see how a Pi Speedtest behaves the next time I try v15.
