Intermittent broadband since Nov30th

Hub 5 - MODEM MODE ON

Hardware version 1.1

Software version LG-RDK_11.6.2-2410.1

DrayTek Vigor2862 router

ethernet connected Mac

GIG1 broadband (only see 500Mbps if I'm lucky for months using Chrome/Speedtest)



broadband suddenly drops out immediately but immediately reconnects

external VoIP service being used suddenly drops after a period of time on a call and doesn't reconnect

but you can call back and its fine again for the next few calls

Service status said broadband issues earlier in week and now today it told me to book an engineer, which I've done. 

just spent 60mins! pulling teeth with online chat trying to find out what has been going on in the area. They managed to clear security, ask what the issue was, did I use ethernet or wifi and then I gave up! 60mins to get to that part of the conversation...I could count the replies on two hands....insane 

Don't think I've been getting my full speed for some months, but I gave up testing as I figured my browser might be to blame and my OS was way outta date (not now)

The drop out issue only started Sunday Nov 30th, noticed it on streaming radio...but figured might be the station. However using computers has highlighted that its the broadband (Macs, Windows, various VPNs etc)

rebooted the perimeter router on Tuesday and its better... but speeds are way down, regardless of the tester I use.

any thoughts? 

Virgin rep help please

...TIA

    VoIP echo can be affected by SPA112 >> Voice >> Regional settings.

    This is from our SPA112, we are not having echo issues.

    the 'must book' engineer came and went today, nice guy, helpful. Said everything was within spec as far as he was concerned.

    Could see we'd had a couple of signal spikes earlier in the week and that they could relate to the initial net drops we'd encountered since Nov 30th and the continuing VoIP echos I've had since switching to a CISCO spa 112/BT phones back in 2023.  He suspects that networking has probably resolved whatever issues was causing our intermittent outages.

    He also said his tool was seeing good speeds.

    explained I suspect my browser wasn't speed testing correctly, and that I'd run a test from another PC on a seperate VLAN only this morning. Was seeing close to paid-for speeds, so I was pretty happy its all working as it should.

     

    ....as you see, 878Mbps with a listed max400Mbps firewall. This has been my experience with my last 3 Drayteks, getting way over the listed max throughputs.

      Thanks for coming back to us, moof and we're glad that you're now getting the speeds that you should be. Please do let us know if you have any further issues.

      Kind Regards,

    I don’t know about Draytek modems, but my modem has an in built Speedtest which is like running a test from the VM hub. Here are my stats from my daily test:

    Dec  4 04:28:33 udmpro udmpro linkcheck[867]: linkcheck.run_speedtest(): Completed: Downlink 1159.000 Mbps, Uplink 107.000 Mbps

    The firewall on that model is only rated at 400Mb so that could be part of the problem? Have you HA switched on if available? 
    Also setup a BQM to monitor and record your incoming circuit http://www.thinkbroadband.com/ping  

    The other point is VM will want the Hub in Router mode before they will do any diagnostics.

    I’ve had a couple of Drayteks and found them to be very good.  I only changed as the throughput on IPv6 on my last model was slower than expected as Draytek confirmed to me that HA did not apply to IPv6.

      cheers Adduxi, for the reply

      Routers been in place since 2018. From 2022-Dec 2024 I would see >900Mbps speedtest.net irrespective of the listed spec of the Firewall: Up to 400Mb/s max. Still have all the test results on a now horrid graph (what happened @ speedtest.net?)

      Into 2025 and my speedtest results started coming back way down and I figured something was going on in Mac/Chrome and as I was running such an old macOS I just kinda stopped testing speed regularly....other test sites gave higher results...but I digress

      The intermittent outage drops / VoIP fails are a new thing. Its been very wet of late so I wouldn't rule out water ingress in the street box.

      engineer is coming Tues (but no idea why they suggested that on the status page) but I booked it regardless

      I'll setup a BQM and see whats gives

      Thanks again

       

      ps: HA is not active (didnt even know the setting was in there)

        Yes, it offloads the packet loads to a dedicated CPU for processing and speeds things up quite a bit.  The problem for me came to light when during a speed upgrade with another ISP, I noticed IPv6 was very slow.  Turns out, after discussions with Draytek, HA is not applicable to IPv6, and the next router up that could handle IPv6 speeds, the 3912, was too expensive, otherwise I would still be using Draytek.
