Terrible speeds

leigh36295 — Tue, 06 May 2025 08:28:19 GMT

Hi, I've been a customer for years and the Internet been terrible the whole time but just put up with it as just seems like a bad area.

I'm currently paying £28.99 a month for a 4.1Mb minimum guaranteed speed with unlimited fibre. If someone's watching netflix in one room it'll make another device lag and buffer constantly.

I was going through the whole process of setting up as a new customer yesterday with plusnet and it's showing me the best deal I can get for this address is fibre at 25.99 a month and 20.3Mb minimum guaranteed speed.

Trying to find out if there's a way the service I'm paying for can actually be improved because as it stands 90% of the time I'm using a wireless hotspot from my phone using 4g as its better speeds, so tempted to just cancel the plusnet contract.

@leigh36295 Welcome to the Plusnet Community Fora.

Your potential maximum speed on FTTC is dependant on the distance between your property and your local street cabinet.

It's quite likely that streaming Netflix will result in buffering problems on a 4Mbps maximum connection

What results do you get if you put your phone number or address in here: https://www.broadbandchecker.btwholesale.com/#/ADSL (if you have no PSTN phone then select the address tab? Also, is WBC FTTP shown as available?

Are you connecting via WiFI or over an Ethernet cable? If WiFi, what speed do you get when your hub is connected to a computer via Ethernet?

Thanks for getting back to me.
WBC FTTP shows as unavailable. The main tv is connected directly to the router but everything else is WiFi. I don't have a PC that I can connect a ethernet to.

I'm not sure this helps but on the broadband checker site it shows:
VDSL Range A (Clean) 30,20.9, 6, 3.7 and 18

VDSL Range B (Impacted) 30, 18, 5.9, 3.7 and 14.6

FTTP on Demand 330, 50 and available

@leigh36295

It looks like you should be able to get much faster speed, but it’s been so slow for so long the Openreach database has adopted the lower figure at some time, now corrected. The first thing to do is eliminate the possibility that this is being caused by your internal wiring. Is your hub connected to the BT master socket or extension wiring? It should be connected directly to the master socket.

Next remove the front from the master socket, you may need to remove two screws. In the back box you will find the test socket. This should disconnect any extensions. Plug a filter in the test socket, connect to your hub and check your speed.
Report back the results.

I've done what you said in regards of the master socket and it does seem to have improved somewhat. Yesterday the speedtest was around 4.3Mbps and I've ran 3 today showing, 7.38Mbps, 5.1Mbps and 8.5Mbps. Seems to be fluctuating a little. Is this something that should stabilise? Thanks

@leigh36295

Is it fluctuating or slowly increasing? If this is the cause of your problem then you might expect it to increase over the following days as the automatic DLM reduces your SNR. You can monitor this if you log in to your hub advanced settings and go to, if I remember correctly, the Technical Log.

So leave it in this configuration for a few days and see what happens.

Do you have any extension wiring? Do you have a filtered faceplate, or do you use plug in filters?
