Speed slowly dropping

fabwhack — Sat, 21 Sep 2024 11:41:38 GMT

When I moved to Plusnet several years ago, I was getting around 70Mb/s download. Over the years that's started to drift downwards, but I'm now below 50Mb/s and things are slowly getting worse - certainly consistently below the advised average of 66Mb/s I should be getting.

The official Openreach Speedtest shows my download speed as 48Mb/s. My router (a DrayTek) shows

Profile	State	UP Speed	Down Speed	SNR Upstream	SNR Downstream
17A	SHOWTIME	18,580 (Kbps)	52,617 (Kbps)	6 (dB)	6 (dB)

FTTP is (literally) just around a corner for me, but whilst I wait for it to be available could someone check my line please, or advise if there's anything else I can do? Router is plugged directly into the master socket, with nothing else connected to the phone circuit.

Can you share a bit more data - Connection time would be a start?

@fabwhack You asked this almost exact question 2 years ago.

I asked at the time

When I first moved to PlusNet, I was getting around 70Mb/s download speeds. Over time, this dropped down to around 55Mb/s - not terrible, and fast enough for what I needed. However, over the last few days I'm now getting half of that! PlusNet / Openreach say I should be getting between 50-70Mb/s.

and my further message:

Thank you - the Openreach engineer fitted a new faceplate, and this resolved the issue.

So original problem wasn't 70Mb/s going down to 48Mb/s, it was 70Mb/s going to 50-odd/Mbs and then suddenly 25Mb/s. Again, this was an equipment fault - replacing the faceplate took me back up to 50-something Mbs.

Since then, I've watched my speed descend over time down through the 50's to now high 40's.

My connection time as of this morning was 77 days, but after a restart and retest both the router advertised connection and Openreach test show the same figures.

OK. It just sounded amazingly similar. Does the Draytek have an understandable error log which you can post?

Not quite what I was asking for, but it does tell me there is nothing inherently wrong with the connection as it stands.

Sorry to ask for more information, but can you post a screenshot of the result from: https://www.broadbandchecker.btwholesale.com/#/ADSL , or https://www.broadbandchecker.btwholesale.com/#/ADSL/AddressHome - remove your personal details before posting?

I take it from that that you are on a SoGEA (no phone) connection? Given your BTW speedtest result of 48Mb/s, I would suggest calling PN Support and reporting a fault, as you are at the handback threshold.

fabwhack — Sat, 21 Sep 2024 14:14:25 GMT

I'm not familiar with SoGEA, but from what I'm reading (https://www.plus.net/broadband/discover/what-is-sogea/) it's "Fibre broadband without a landline". However, I do have a traditional lineline - there's a Master socket with a BT jack that I could plug a standard landline phone into, although there's no landline plugged in any more, and this also has the router plugged into it. FTTP isn't available in my street yet.

Even with this is mind, would it be advisable to raise this with Support?

Re: Speed slowly dropping

jab1 — Sat, 21 Sep 2024 14:21:55 GMT

OK - it was the fact you used the address version that made me assume you were on SoGEA. I would still contact support, but given that your router is reporting a connection speed above the 'impacted' minimum rate, they will probably say they are satisfied with your connection speed and there is nothing they can do.

Disappointing, but I understand - I've watched the connection speed slowly drop month by month, so with the current trend it doesn't seem like it'lt be long before it actually does trip over the minimum. Hopefully FTTP will arrive here before then! Thanks you for your help anyway.
