this of course means that the router will have just been reconnected.

No, it wont. I beleive RobertoS is referring to a complete re-sync.

I must be being sleepy. I didn't pick up on that.

PC >> Ethernet >> Router >> Cable >> Filter >> Test socket.
We only have the phone line for the internet and don't have a phone plugged in.

How can i make the router do a complete resync?

Turn it's power off is simplest .

Those latest stats are garbage and suggest a faulty router. Or somehow in getting to here the figures for attenuation and noise margin have been swapped over. What are they like after you turn it off and leave it off for 5 minutes before turning it back on please?

Very similar:

So i have low attenuation, and a very high noise margin? The high noise margin might be due to the low sync speed for the attenuation on the line? So it has more margin in hand and could potentially connect at a higher speed?

Hi memsb,

If you can PM me your username I'll take a look for you.

Nope.

If you look at the stats from a different router that you posted at 12:03, and appear to be from 14 December, the Loop Loss, which is another name for Attenuation, and the noise margins, both look sensible, and correspond closely to ones from the Linksys if the attenuation and noise margin data from the linksys are swapped to each others description. Oh - just realised, on the Linksys the Up/Down headings are also obviously reversed, though correct for the power figures.

In particular, we expect the upstream attenuation to be about half the downstream, and re the noise margin the 6.45dB downstream figure straight after a reconnection is a highly likely reading and the ones reported are impossible - the system cannot assign such margins. The downstream rate is also consistent with that 6.45dB margin on a longish line (50db-ish attenuation), but is still low.

How recent is the LInksys firmware/driver? I had a WAG54GS a few years ago and don't remember this problem. Ah - Aug 2008. Is there an update available?

Another noticeable effect is that it is reporting ADSL2, whereas your Plusnet setting is almost certainly ADSL2+. Or have you forced it?

The 52.5dB loop loss falling to 50dB is consistent with that change, but the earlier 48.5dB looks strange. In particular the attenuation on any particular router should not change by more than 0.5dB, ever. Though different makes can calculate it differently, (it is an average of the individual attenuations at each frequency and it seems different manufacturers use different criterea for including particular ones), which is something I haven't considered above.

I don't think I would be using the Linksys if I had others available. Is there a particular reason for it?

The 12:03 data i posted was from what plusnets support system shows in the faults log from when i ran the BT speed tester, it's not come from a router info page. The test was performed using the same linksys router. The linksys is being used as it's my only outer, i have in the past borrowed routers from friends for testing purposes however both of those routers were wired only and i would like to use wifi.
I thought a firmware update was needless as i thought i had ruled out the router as being the problem by using different ones. I shall try doing a firmware update.

I didn't realise you were talking about the columns on that output data being switched, i thought it was the rows that were being suggested were the wrong way round. I guess I just ignored the headings and assumed it would be in Download / Upload order.

DSL mode is set to MultiMode and appears to have picked ADSL2 by itself. I could force it to:
ADSL2
ADSL2+
ADSL2 L
ADSL2 M
ADSL2+ M

The rows are wrong way round, as well as the headings . The 12:03 ones are the right way round.

Have you checked that link I gave you for the Plusnet line rate? That can get out of step. The BT speed test value should be similar but may not be. At the moment you aren't giving me either, at their current values . 14 December is useful but not hugely so now.

This test was not conclusive and further testing is required.This might be useful for your ISP to investigate the fault.
