Full Fibre Speed Test

crimsom — Fri, 29 Oct 2021 21:23:29 GMT

Have recently moved from FTTC to FTTP and using BT phone number with the BTW Performance Tester (btwholesale.com) does not register my FTTP speeds.

Ethernet connection to Speedtest by Ookla - The Global Broadband Speed Test says my BT Full Fibre 100 plan speed test is 10 ms Ping, 94.59 Mbps download, and 28.88 Mbps upload. Windows 10 says download Ethernet Link speed is 100/100 (Mbps), but my BT 100 plan is 150 Mbps download speed with the BT Stay Fast Guarantee of 100 Mbps and upload speed of 30 Mbps.

Although online full fibre speed is still being assessed for my line, it will never get 150 Mbps whilst the BT 100 link speed maximum threshold is set at 100 Mbps.

Is BT monitoring my new BT Full Fibre 100 plan, to automatically instigate download speed correction without my intervention?

Try using fast.com with ethernet cable

Hi @imjolly have used four online ethernet speed tests:-
1. Broadband Genie says 94.41 Mbps Download, 30.00 Mbps Upload.
2. Fast.com (powered by Netflix) says Latency Unloaded 3 ms Loaded 120 ms, Download 90 Mbps, Upload 29 Mbps.
3. MoneySupermarket says 92.2 Mbps Download, 28 Mbps Upload.
4. Speedtest.net says 10 ms Ping, 94.59 Mbps download, and 28.88 Mbps upload

These ethernet full fibre speed tests are all less than the BT Stay Fast Guarantee of 100 Mbps.

Bear in mind all the speeds quoted by BT are connection speed to your hub not download speed at your devices

Openreach Full Fibre 2nd Stage Engineer says my ONT modem hardware installation can deliver 1Gbps to devices in my House. Windows 10 says BT Plan Ethernet Link maximum download speed will never allow more than 100 Mbps. The new BT Full Fibre Plan fails to deliver the advertised download speed of 150 Mbps.

The Ethernet cable is plugged into the BT Smart Hub 2. The BT Plan is not delivering the BT Stay Fast Guarantee of 100 Mbps. Openreach Full Fibre 2nd Stage Engineer says there no hardware fault that prevents getting more than the advertised 150 Mbps.

Something has gone wrong and I am not on the correct BT Full Fibre Plan. The Ombudsman review of BT Deadlock letter option to terminate the new BT Full Fibre Plan with no penalty is being considered.

Why is it apparently difficult for BT Journey to deliver the agreed contract?

It would appear your PC/laptop only has a 10/100 Ethernet card rather than a GbE card.

FTTP can deliver more speed than you currently pay for , but it’s unlikely that you have been put on the wrong speed profile as you comfortably exceed the 80Mb download profile , you therefore are ‘connected’ at at least the speed profile you pay for …this connection is set, it doesn’t vary , it’s not observable by you, by looking at the router stats, or ‘windows’ , and they way the system works you are either working or not, there is no variance like ADSL/VDSL, if the correct profile is set, you get the connection speed you pay for.

As already stated , download and connection speeds are not the same, download is affected by many things that your provider and Openreach have no control over, in your case D/L is pretty close to 100Mb ( which coincidentally happens to be the minimum speed guarantee and the limit of older Ethernet equipment fitted in some PC/laptops …as already stated it’s entirely possible that it’s now your own equipment that is limiting your download speed .

FWIW, Openreach FTTP ( PON) is a system where up to 32 users ‘share’ bandwidth of 2.4Gb download , 1.2Gb upload, if you happen to be connected to a PON that’s got all 32 possible connections in use and many are intensive users , you may see speed dip, but in general it’s more than enough bandwidth, if you feel it’s not enough ( 2.4Gb ) , do a speed test at a quiet time of day , avoiding peak hours (6pm till 90pm or whatever), if no difference then it’s not over-utilisation, again proving the PON is delivering what it’s supposed to and indicating it’s your own gear.

As far as being excused your minimum term commitment because your perceived performance is fractionally less than the guarantee, then that’s unlikely, because it’s more likely that there is nothing wrong and it’s your own equipment that’s now limiting your speed, finally , if you were getting 100Mb ( thereby satisfying the minimum guarantee ) instead of 90Mb , in day to day use there is going to be noticeable difference anyway.

Yes, this is the problem. You said it in your first post.

The Ethernet link speed is 100Mbps so you’re never going to get beyond higher speeds unless you can resolve this issue.

This is the physical link speed between the PC and router and nothing to do with what the broadband can deliver.

That shows 1Gpbs. I thought you were saying that Windows was showing 100Mbps?

Hi @dave44 I have revisited Windows 10 Pro version 21H1 and it says says download Ethernet Link speed is 100/100 (Mbps), and OP does not have a typographical error. The dogma to always use Ethernet during speed tests was followed. Intuitively, Device Manager has now been asked to scan for hardware changes and did not find any new hardware changes. However, Windows 10 now says Ethernet Link speed is 1000/1000 (Mbps). I do not pretend to understand why the Windows 10 Ethernet Link speed has changed. Ethernet Speedtest.net now says download speed is 150 Mbps.

@crimsom

What can happen is that Ethernet link speed auto-negotiate, can select the wrong speed due to link timing issues between different devices, especially cheap consumer hardware.

You can prevent this by configuring the Ethernet adapter on your computer so that its set to 1000mb Full Duplex, and not auto-negotiate. This is a very common problem and has been reported before on this forum.

See https://en.wikipedia.org/wiki/Duplex_mismatch

It can often be corrected by putting a 1Gb Ethernet switch between the LAN port on the home hub, and the LAN port on your computer. Ethernet switches are better at analysing the link pulse to determine the correct rate.

Hi @Keith_Beddoe My Dell Alienware 17 R5 laptop with Windows 10 Pro is £2,400 and I consider this to be an expensive laptop. The BT Smart Hub 2 Ethernet ports should be sufficient and not require an additional 1Gb Ethernet switch. Seemingly the cheap BT Smart Hub 2 (aka Home Hub 6DX) needs another upgrade.

Re: Full Fibre Speed Test

The smart hub 2 is just a cheap mass produces ISP router, so the hardware manufacturing tolerance is not going to be that narrow, unlike expensive commercial equipment.

The Ethernet link pulse is very short and if the data within it is not interpreted correctly, then you end up on the wrong speed, which results in a default of 100mbs. Just lock the Ethernet adapter to 1000mbs, its normally an option within the device properties.

Ethernet Link Speed Capped at 100 Mbps (intel.com)

There is no option for 1.0 Gbps Full Duplex with Killer Ethernet drivers. Auto Negotiation will give a 1.0 Gbps link speed, provided your other networking equipment auto-negotiates correctly. Auto Negotiation is the correct setting for Gigabit speeds in Speed & Duplex for Killer Networking Adapters.

Killer Control Center: Network Settings are Download speed 1500 Mbps, and Upload speed 1500 Mbps.

Having used the Ookla tester to see good results, I wondered why the wifi link to an Android 'phone was so poor (typically 30MBd download, but better upload!). After extensive testing, I realised that far better performance could be achieved by turning off the 2.4GHz wifi, and forcing the 'phone to log onto the 5GHz band (>100MBd.) It turns out that for my Samsung 'phone, setting MAC address type to "Use device MAC", as opposed to Randomised makes the 'phone use 5GHz if the signal strength is good enough. Simples.
