Since last night 20/10/2020, I've had slow network speeds. I did a speed test and was shocked to see 200ms ping and sub 10Mbps download, I left it as sometimes this happens and assumed it would return back to normal. I've come onto my desktop today and ran another speed test to find that every speed testing website I go on thinks I'm connected through Vodafone as my service provider. This has happened on my phone also, however, sometimes it seems to switch between being recognised as Vodafone and BT, where each one has drastically different speeds. When it displays BT as my connection it is as expected, at about 70Mbps, but always below 10 when it is showing as Vodafone (which is basically all the time). I can't for the life of me figure out why this is happening, especially on my desktop which is plugged via Ethernet into the Hub downstairs. This is driving me crazy, does anyone know what this could be? I have included some test results in this post to show how it has differed since a previous record. Speedtest clearly shows that it thinks my provider is Vodafone. Very weird.
Solved! Go to Solution.
Check your phoneline. 17070 option 2. Best with corded phone. Make sure it is your phone number that is repeated back then wait for the quiet line test to complete.
I haven't got a corded phone, does that matter? I rang the number and selected option 2 and it just kept repeating "Quiet line test" with some white noise in the background
Did it read back the right number? It should be totally silent between the announcements. Its possible your line is shorting to another line somewhere maybe due to water ingress in an underground joint.
Do you use powerline adapters?
So I just checked my speedtest results and my IP is actually different when getting the Vodafone results. I forgot the network on my phone settings and it went back to BT for a short period of time and has since reverted back to a different IP and provider. I think that there must be some interference or something with someone else’s Vodafone broadband. We’ve had a new neighbour so I assume they have had Vodafone broadband fitted?
Your phone should not connect to next door wireless, as it should have a password, unless of course they have removed the password and are running an open network, or have another wireless access point which is open.
Not a secure way to run their network.
You should be able to alter your phone settings so it will not connect to insecure networks, as someone could intercept your connection.
Also, as @imjolly has said are you using any powerline adapters to connect your network together? These use the mains wiring to carry the Ethernet connection.
What I mean is, I’ve been connected to my own network in my settings, however when running a speed test it thought my IP was different to what it usually was and had the wrong provider. I’ve reset network settings on PC and reconnected to my own network a few times and it’s working temporarily currently. It was strange, I was connected via wifi to my home network the entire time and it would think I was connected to someone else’s broadband (different IP and provider on the results i posted)
For the third time, can you please answer the question regarding Powerline adaptors.
