Difference between the Test Socket and the Faceplate?

I have been doing some tests on my Vodafone broadband as some downloads were going more slowly than expected. They asked me to do some tests with the router plugged into the Test Socket and no other connections apart from the laptop, connected via Ethernet to the router.

The test showed I was getting less than the guaranteed minimum speed, 59Mbps instead of 63Mbps. They then said I should leave the router plugged into the test socket for 24-48hrs "to fix the problem."

I tried getting them to explain the difference between the test socket and the one on the faceplate but they were unable to give a satisfactory answer. Can anyone here explain please? BTW, the router status shows the line speed as 67Mbps when I looked towards the end of the chat, so I don't know if it had been tweaked after I started the chat.

The test socket isolates all other items from the incoming circuit, including any filters in the faceplate (or elsewhere) and any extension wiring.

It (should be) the most ‘pure’ connection between you and the network.

How would being connected to the test socket fix any broadband problems?

Its there to help identify issues not to fix them, when using the test socket it ensures internal extension wiring that could cause a problem is isolated. If they are claiming this has fixed the problem then thats not the case.

It fixes the problem from the perspective of Vodafone - if everything works in the test socket then there's no problem that has anything to do with them.

Just to add to what others have said…..

Extension wiring, unfiltered equipment connected to the line, are common causes for sub optimal speeds.

Connecting with just the router connected in the test jack should help identify if this is a cause.

The suggested time to leave the line set up like this is due to Openreach line profiling which can cap sync speeds in response to issues, so leaving for 48hrs ought to see an improvement IF this has occurred.

Lots of other stuff can be an issue, but trying the suggested can eliminate a common issue.

That's the most sensible explanation I've heard. Although surely once you reconnect the faceplate the system will revert to how it is now?

Well, yes. If the Openreach line profiling has upped your speed a bit it will actually be a bit worse until the line profiling trims the line back to how it was.

But then, if you discover a problem using the test socket, it is up to you to decide whether to do anything about it.

Quite.

That's the point. The demarcation / point of responsibility for Openreach is the master socket. Anything beyond that; I.e. any internal extension cabling, filters, other devices etc. are (a) completely your responsibility (b) may be impinging on the quality of the service, hence affecting your speeds.

Therefore Openreach only want to test the basic circuit with nothing else in the way. That's just logical, isn't it?
