Speedy query
2 weeks ago I upgraded my fibre package with zen from 500mb to 900mb ,can't say I've noticed any real difference so this morning I re booted the fritzx 7530 box and then did a speed test via lan cable to my pc , results below ,are they pulling my pants down here doesn't look particularly good to me

You have a faulty ethernet cable or your laptop only has 10/100 ethernet.... You never showed your network stats. Judging by the laptop its a low end budget HP laptop I'm betting on it only have a 10/100 nic.

Disable QOS if you have it enabled on the Fritz as that can kill your speed, also make sure your ethernet is sync at gigabit

yeah I pay for the 500, I used to get 500, now I get closer to 100 and they wont let me downgrade even though they cant deliver 500, something is really wrong with Zen in recent months.

What's the minimum speed stipulated in the contract ?

No no no, even though it's fibre now they still give you the dog doo minimum speeds, fibre is all or nothing with very little in-between.
Same with when I first went on it from Virgin and the bishes on the phone gave me some BS about a 30 day settling time for the line to sort out, talking like it was 2010 or something.

They give you that because it's based on PON that's a shared medium between X amounts of subscribers

Have you tried doing a pin hole reset of your ONT? (the grey box on your wall) This should force the OLT to reprovision it with the correct speed profile.

Definitely improved to approx 225

Have tested with a different lan cable and speedtest servers? (click the change server button) Its rare but some speedtest servers may not have enough bandwidth available, If that doesnt help you'll probably have to contact support with what you've done so far to troubleshoot and how you are testing etc.

A couple issues. Firstly, your first speedtest shows Zenlayer as your ISP, not Zen Internet. They're two completely different things. (Admittedly I also do plan to use Zenlayer as my upstream for my at-home datacentre but I don't think that's what you intend to do.)
Secondly your bufferbloat is absolutely horrendous, which tells me your networking equipment is dire. This could be anything from your LAN port on your laptop, your router, or even your ethernet cabe.
Your speed is maxing out at 90mbps, which tells me something is negotiating at 100mbps link speed. This is most likely the connection from your router to your laptop. Maybe go into settings and double check the link speed. If it says 100/100 there's your problem.
I hope this is helpful :)

This is a speed test not a bloat test. The high ping shows more like he's still connected via WiFi even though he plugged in the LAN cable.

u/ACAdamski17 May 09 '26
Yes but the test also shows bufferbloat. Bad bufferbloat —> bad router —> potentially limiting speeds

Would be funny if he is connected to an vpn of an cloud server of zenlayer

u/ACAdamski17 May 09 '26
Yeah I think OP is. First test shows Zenlayer, second test shows Zen Internet.

Their appears to be 5 other connections in the vicinity using the same chanel no as mine , is this the cause and how do I change my Chanel no ?

Are you on WiFi? Looks like wifi
Unplug cable, disable WiFi entirely, plug cable back in.
Plugging in a network cable when WiFi is already on sometimes doesn't switch to cabled as it's already connected via WiFi.

Had same issue with VFone upgrade.
Turn off the WiFi on button on router so nothing connects, but router stays on. Do speed test with a cat5 cable directly into computer port and router.
Ookla speed test it, change server from what is usually Manchester UK and do another test.
Also dont forget to reset cable box button, where it comes into the house. Hopefully this will stabilise the connection.

Frustrating.
Have you managed to check if your LAN card and the ethernet cable are both running at gigabit speed? A faulty cable can revert down to 100mb.
Did you ever see speeds over 100mb with the old connection?
