Went live 7hrs ago and its been eratic

Thanks for the suggestions from various folks, including YayZi Staff: much appreciated.
As I am a new customer I had no idea the current cutomer portal was being decomissioned.
Even the welcoming email took me to the portal.
No wonder my tickets filled in there have gone onto a black hole.

Regarding the methodology I’m using for the speed monitoring, here are a few more details:

I using a few DMS-107 2.5 G switches from D-link to ensure my link speeds are always at the highest speed.

I even temporarily used one to confirm the link between ONT (latest version installed by City Fibre yesterday) and the WAN socket of the EX820v are lighting up blue on the ports - indicating 2.5G link speed. So that is fine.

On the YayZi supplied EX820v router, I’m definitely using Lan 4 to attach to a WAVLink USB C Ethernet Adapter which runs happily at 2.5G

I have a RPi 5 connected to three networks: WiFi for VNC monitoring using wlan0, eth0 for a 1G link (to OpenReach via Fritz!Box) and eth2 (to CityFibre via the EX820v)

I can selectively down/up the eth0 and eth1 interfaces while still accessing the RPi remotely via RealVNC Viewer

Ignoring the overhead of web browsers, I can run speedtests selectively from the command line on the ethernet interfaces and get realistic ideas of the speeds.
I intend to repeat the tests at different times of day but I’m immediately seeing under performance.
With previous ISPs I know the CityFibre can upload at 1Gbps but I have never seen more than 622 Mbps via Yayzi
Example from around 10am this morning, probably the best result I’ve seen so far:

Howard@PI-5-4GB:~ $ speedtest
Retrieving speedtest.net configuration...
Testing from Yayzi Broadband (nnn.nn.nn.nnn)...
Retrieving speedtest.net server list...
Selecting best server based on ping...
Hosted by Vodafone UK (Watford) [299.83 km]: 8.838 ms
Testing download speed................................................................................
Download: 1652.72 Mbit/s
Testing upload speed......................................................................................................
Upload: 622.05 Mbit/s

Maybe my expecations are too high?
I was sold on the possibility of multi-gig by Chris in the Customer Support Team when I made an enquiry earlier in the year and he confirmed Yayzi could supply a 2GB service.

Realistically I cannot see my self commiting to Yayzi unless the upload speed improves to levels closer to 1G (when I’ve previously had a symmetrical 1G service from a different provider, admitedly at higher cost point).
This smacks of bandwidth management to me and not a physical limitation on the fibre to my premises.

I do love my diagrams!

And 30 minutes later it back to poor:

Howard@PI-5-4GB:~ $ speedtest

There is no other traffic while doing my test. The RPi is the only device connected to the router. I don’t see this variability with my provider on OpenReach.

What do you get on here?

You can use iperf if you like :slight_smile:

think you can do iperf3 -c proof.ovh.net -p 5210 -b 1G -l 32K -R

Or try this iperf3 -c proof.ovh.net -p 5210 -u -b 2.5G -t 60 -l 1400 -f M

I slightly modified the parameters, but for better or worse I got:

howard@PI-5-4GB:~ $ iperf3 -c proof.ovh.net -6 -p 5210 -u -b 2.5G -t 15 -l 1400 -f M --version4

iperf Done.

I’m not famliar with interpretting iperf3 results. Should I be seeing 57% on the receiver? Maybe the issue.

BTW, setting -l 1268 I still get (56%) receiver

Shouldn’t be getting drops no

Good suggestion. I’ll try and put my hands on a laptop or similar that has a 2.5G i/f but it may be some time. Right to question the USB C. Thanks.

We’re looking into this, if you could disconnect absolutely everything and if you have a PC (with a 2.5Gbps network card) directly into LAN4 on our router.

This just helps us rule out anything from your side, as we don’t use any traffic managment at all.

We have seen some screwy results via USB-C - We’re all here to help so between us all we’ll get it figured out :slight_smile:

Can you speedtest directly from the router? Like I am on a 1.2G service and my PC’s get 940mb/s down/up, but the routers on 2.5WAN gets 1.2Gb/s down, 1g up… LAN side is on 1g

image
or as @Yayzi_Team says, plumb directly into the matrix

If it helps heres a custom temp AWS iperf3

Will only be up for 1 hour.

Thanks Yayzi Staff.
I’m now in correpondance with Stefan from Support.
I’ll shut up for now on the forum. But thanks all for the useful suggestions - we’ll get to the bottom of it.

You are welcome!
Let me know if you need the AWS instance brought back online if you wanted to test against it :slight_smile:

I take that comment bck about saying yayzi are out of depth running a isp,that was a bit harsh,I was tired and frustrated trying to explain my issues with emails,even though I waited a few hours for a reply they were genuinely nice and trying to be helpfull and I wish the yayzi team all the best

They do try their hardest. I’m sure they appreciate the apology. It’s very warm in the UK so I get it :slight_smile:

This is worth a look, adds a splash of generative AI. Can use natural language and it’ll create diagrams. Not perfect though as with all the AI.

Hi yah, Can you help with configuration rt-ax86u router pls, I cannot find vlan option.

Thank you

I think Asus firmware pls,

I have one of these routers in the cupboard. I will dig it out tomorrow and have a look.

Hey, If I were you I would start from installing the newest Merlin firmware for it, then adjusting the settings.
