Leave it a few more days.

It doesn't look like GINP is switched on yet assuming the VF router can support it. Your line attenuation is almost identical to mine and your sync rates matched mine without GINP enabled.

Assuming you aren't on an ECI cabinet, GINP when enabled should give you around 50 meg sync speed.

If DLM lowers your SNR to 3dB, you should get close to 60Meg sync, - which is what I'm on.

I have just found out my old SSE Technicolor router, got my username from VF and connected it. Sync has immediately improved, but still not enough to get over the 55 guarantee.

Line Rate 13.53 Mbps 48.6 Mbps
Output Power 6.9 dBm 6.9 dBm
Line Attenuation 2.8, 28.1, 45.7 dB 15.4, 37.3, 57.1 dB
Noise Margin 6.1 dB 6.1 dB

Obviously the VF app won't now connect, so will have to go around the houses to try and get any info out of VF, let alone invoke the guarantee as allegedly you can only do it through the app.

Bear in mind that newly provisioned VDSL2 connections (e.g. different backhaul, change of package speed) will effectively reset DLM. These days the default profile is downstream at INP 3 delay 8ms instead of fastpath (if you are connected to an ECI DSLAM), this will become fastpath after 48 hours or so unless DLM determines there's some instability. This was previously only applicable for connections on a Huawei DSLAM, due to G.INP taking over later on.

I'm not very techy when it comes to the 'net unfortunately. From what I had read in the past though, I thought that the 10 day thing was a myth on fibre lines as the line should always sync at its highest rate. I also believed that DLM would not necessarily reset by default on a migration. I have no idea what DSLAM I am connected to (Cabinet 3, Sandy if anyone would like to find out), but have remained interleaved for the last 96 hours. That said, it took months for interleaving to be turned off and I am wondering if this is going to happen again.

The DLM 10 day thing is a myth

The lines start as a fairly plain VDSL2 connection, but some enhancements only get enabled after a week or two, e.g. G.INP and lower target noise margins which can actually boost speeds beyond the standard assuming your cabinet is Huawei based.

Sandy cabinet 3 is ECI based so no G.INP

So time to wait and claim the 15% off

Thank you.

I'm getting conflicting results from testers: Testmynet I can set to run x amount of tests every x amount of minutes, which is handy. It is showing the following graph, with the slowdown from 1pm.

https://testmy.net/stats/?&t=u&d=09032018&x=12&l=500...

The TBB test doesn't show as being so bad.

Testmy net is wired and single thread, TBB is wireless on different pc's. There is definitely something amiss on the connection, even with these results as Facebook/ Youtube videos buffer, more of an annoying screach in the sound as opposed to picture freezing. Could be using my 30 day guarantee to leave.

"even with these results as Facebook/ Youtube videos buffer"

Notice how on the https://www.thinkbroadband.com/speedtest/15359947856... test that the speed is not consistent for the single download, so while nominally speeds look good, that dip from 6 seconds onwards would probably lead to problems with some video streams.

Its a classic case of the numbers look nice, but underlying data suggests something may be amiss.

The presumption is the the testmynet was not running when you ran our speed test, as that could cause exactly what you suggest and as the graph on that site suggests you are running the test a LOT then the act of running the test might be the cause of the streaming issues.

NOTE: Used to have streaming issues on my Vodafone connection until adding a bridge modem into its WAN port (under a sticker) did some swapping over a number of weeks and it was consistent i.e. when using the Vodafone router as both modem and router it would break the streams/connection every now and then. Now used as just the router it is a happy beast.

Thanks for your reply. It is set to run every 30 minutes, so you are correct that is wasn't running at the time. The video issues aren't happening during test times either.
