Broadband Speed, Am I Being BS'ed?
Discussion
Hi all, upgraded my broadband yesterday from ADSL to Fibre, I was getting about 5-6MB/s with the ADSL, checking today it's absolutely the same, no increase in speed whatever. Also upgraded the router yesterday.
Phoned my ISP's technical support line, after 20 minutes on hold I was told that it was common for fibre to need time to "settle in" and it would become faster over the next 10 days or so.
It doesn't seem plausible to me, but I don't want to argue about it till I find out more, so over to you all, is this a reasonable explanation?
Thanks in advance.

What does http://dslchecker.bt.com say your speed should be? Just because it is Fibre (assuming FTTC) doesn't mean you'll get a speed increase.
Have you actually connected a VDSL router ?
Yes, VDSL can take time to settle, it should train when you turn on the modem, learn what spectrum is available. It then uses these channels to send and receive data. However, because external noise is often transient, this first attempt, is likely not to be able to reject all the noise your line may experience.
Normally it first syncs higher, then tends to drop back as errors are clocked to maintain a working noise margin. It may just knock back a few of the frequencies it uses to transmit data, but if its bad enough, it will start using more effective (and slower) noise rejection strategies. If the DLM in the cabinet kncks your speed back, it can take quite a while of low noise for the speed to recover as its designed to be quick to react to noise and slow to ease back to higher speeds. Somtimes it can even detect enough noise to drop your line onto a semi-permanent noise rejection strategy that needs the provider to do a reset at the local cabinet to resolve.
Whats your router ? You may be able to see the stats from it and determine what type of connection your getting.

Plusnet.
Been with them 8 years and no issues at all with ADSL service, just very disappointed with this "improved" upgrade, not even close to hitting their minimum guaranteed speed and no sign of any increase in speed, hovering around 6MB/s since yesterday and I've been checking every 4-5 hrs, fastest 6.4 (today) and slowest 5.3 yesterday afternoon... same as I was getting with ADSL.

When I switched from ADSL to FTTC a couple of years ago the speed increase was immediate. The line dropped (Zen told me which day the change was happening) & when it came back up I was flying. I guess you have rebooted the router?Been with them 8 years and no issues at all with ADSL service, just very disappointed with this "improved" upgrade, not even close to hitting their minimum guaranteed speed and no sign of any increase in speed, hovering around 6MB/s since yesterday and I've been checking every 4-5 hrs, fastest 6.4 (today) and slowest 5.3 yesterday afternoon... same as I was getting with ADSL.
Can you get any Line Sync information out of the router you are using? It should tell you what speed you are synced at.
Stick your phone number into the Zen checker to see what they reckon you can get:

Speeds can bounce around a bit for the first few days but increase should be immediate unless there is a wiring problem .Phoned my ISP's technical support line, after 20 minutes on hold I was told that it was common for fibre to need time to "settle in" and it would become faster over the next 10 days or so.

That is the problem with UK infrastructure, much of our rural fibre network is in fact FTTN with direct copper lines to the exchange (with 500-2000m spans), rather than FTTC, which requires a cabinet on the street and a ~200m copper span. In my opinion it's typical government infrastructure mismanagement that causes this, the strive to have 99.9% of UK households on fibre & the grants provided to do so means providers push to build fibre only in name, rather than upgrading networks in a meaningful way. Upgrading from ADSL2+ to FTTN can actually be detrimental in many ways as fibre is more susceptible to interference from deteriorated copper lines, meaning fibre upgrades can often lead to negligible speed increases, but reduction in connection quality in rural areas.
The "settling down" is actually called DLM - here is a bit of info on how it works and what it does https://support.zen.co.uk/kb/Knowledgebase/Fibre-O...
It is entirely possible that your connection speed will improve over the next couple of weeks.
