Can't get anywhere need 900Mbps on Full-fibre FTTP with Zen

Hi,

I've recently had 900Mbps full-fibre service installed via Zen but I am struggling to achieve speeds like that, typically getting 300-450Mbps max on speedtests and never seeing anything higher. [Edit: I am connecting over Ethernet, not Wifi].

I am wondering if my equipment is part of the problem. I have a (relatively) old Draytek Vigor 2860 and a FritzBox 7530 which I got for my old FTTC 80Mbps Zen service. Both give the same results.

Can anyone confirm:

1. Is my router hardware likely to be the limiting factor or should one or both of these be capable of 900Mbps over PPPoE?

2. Should I get 900Mbps on a speedtest and if so, which speedtester should I be using and which target host?

3. Is there another way I can test the speed - e.g. via file download and, if so, any URL to the best service to try?

Zen want to send out an Openreach engineer to investigate but I am still trouble-shooting in case the problem is at my end. It would be really helpful to hear from anyone that has already achieved full speeds.

Many thanks,


Tom.

how are you connecting to the routers, via ethernet or wireless ?

By ethernet only, no wifi

I have also noticed my Draytek is going over 90% CPU during a speedtest, which makes me suspect that this might be the bottleneck.

Hi In that case, you could connect your ethernet directly to the ONT removing the router entirely and test that way to see if speed increase. Since I don't have full fibre i'm not exactly sure on the technicals (cable customer) I'm know someone will pick this up and give you info in detail if needed,

Thanks, I will try that. I did have a go doing this with an old desktop, but it is very old so again, maybe it wasn't up to it. Will try with a modern desktop to see if that works.

I assume a modern computer will be able to do 900Mbps PPPoE?

By any chance is it on windows
and do you know what specification is

Anything 8th gen intel I3 or above tends to support it from experience in my testing case 8GB RAM windows 10
on SSD for file download tests since HDD speeds can pose issues

edit
I will add, if it doesn't manage it there is another way and that would be to make a bootable USB stick running linux, it's relatively easy to do but let's leave this option until you test it first

Most modern computers with a 1gb network port should be fine

just create a pppoe connection on windows and plug your cable directly into the ont. It should comfirm if its the routers

thanks for pointing that out, i am so used to them having it now i completely forgot

From the Draytek website for the 2860

Performance:
Firewall: Up to 300Mb/s max
IPSec VPN: Up to 50Mb/s max

So the Draytek is limited by the firewall.
