Slowest ever this afternoon - LLU??

pctech · Oct 15, 2011, 18:33:10

Must be really really congested there Sean.

I can soon tell you if you let me know what exchange you're on (I can check via Be support forum)

Thanks, Griff.

Exchange name:    North Shields
Exchange code:    NENS
Location:    North Tyneside North East

Speed is now 460Mbps (about 0.03 my usual)
ping is 73ms (about double usual)

I'll go and look now Sean. It may require me to ask and therefor wait for a response.

.Griff. · Oct 16, 2011, 12:36:25

There's no reported problems at North Shields Sean and I've also put up a post asking any other Be users if they're experiencing issues in the vicinity but no-one has reported back as yet.

If you've not already done so create a TBBQM and see if that reflects the high latency issues you're having - http://www.thinkbroadband.com/ping/monitors/create.html

Thanks, Griff, for all your efforts.

I've just registered with TBB and set up the TBBQM as you suggested.

This morning the speed was about 1Mbps with sync rate about 17Mbps and SNR margin of 6dB. Over a period of a couple of hours the speed increased a bit to about 1.5Mbps.
After a reboot of the router and now have about 10Mbps with sync rate about 12Mbps but 15dB.

Last night my speed got as low as about 190Kbps, so of course 10Mbps is quite adequate!

We will have to see what happens in peak periods.

Despite disadvantages of BT/21CN, which I was with since April, the speeds were always at least usable. For me, 190-500 Mbps isn't practically usable - apart from anything else, keep going for a cup of tea while waiting for a webpage to load puts too great a strain on my bladder!

Others may have their own views about the advantages/disadvantages of LLU and 21CN, but I've now asked to be put back on 21CN.

Thanks again.

Griff,
I see the ping graph in your sig is different from the one in TBBQM graph being generated for me - eg yours has mean, max, min. Presumably you use a different tool?
Having the mean/max/min would be nice.

Hi SSK. I haven't had congestion here, though the ping is definitely higher on LLU. It used to be about 8ms to the UBR but is now about 20ms. ADSL always seems a bit of a black box to me, so it just seems configurations that are terrible for one person are great for another. Let us know how things work out.

Initially, my fast path ping was faster on the Telefonica circuit than the BT one, by about 4ms, 10ms vs 14ms. The line was not stable with that, as it hadn't been on BT, and the ping is now about 4ms greater, ie 14ms.

So far IDNet seem reluctant to move me back to BT.

After my first email request they asked if I really wanted to move before trying to find the problem with LLU.
I replied that I did.

After that confirmation that I wanted to move I got a response saying:
"so we can have this investigated for you could you provide us with the results from a test completed at www.speedtester.bt.com. We will then log a case and see if there is anything that can be done to improve the service prior to moving you off LLU."

Apparently they don't even know that the bt speedtester doesn't work with LLU.
Also, what is the point of seeing if anything can be done to improve LLU when I've made it clear that I definitely want to go back to 21CN?

I've now sent a third email saying I absolutely, definitely want to move back to BT Wholesale.

pctech · Oct 17, 2011, 15:20:02

Oh dear, someone at IDNet towers has obviously made a genuine mistake.

Simon_idnet · Oct 17, 2011, 15:30:54

It's no porblem to move you back to BT Wholesale, we were just asking if you might want us to try to fix the fault before we did. Not to worry.

Technical Ben · Oct 17, 2011, 16:04:14

It's easy to pick up the "petrol" pump when you just bought a diesel. We are all human.

I'd prefer to find the fault before moving back myself. IE it could be totally unrelated. A move now could make it harder to find the real fault.

Steve · Oct 17, 2011, 18:42:14

Especially if the fault carries over back to BT

I had set the LLU Service Profile to ADSL2 (12Mbps) to see if that helped. I've now reverted it to ADSL2+ (24Mbps). Please can you reboot your router again?

SSK · Oct 18, 2011, 09:35:52

Okay, the sync is now 19.3 Mbps and the download throughput is 16.3 Mbps. Ping average is 20.1 msec, max ping is 38 msec.
Obviously, more than just satisfactory!

(It is also better than I had with BT Wholesale)

Because of what happened at the weekend (190-500Kbps for several hours) and the fact that it happened only after the switch to LLU, there is still the concern that it might be due to BE congestion at peak periods and might happen again. If it was due to congestion then BT is prefered because a reliable constant 12 Mbps all the time is better (IMO) than 16 Mbps on weekdays wirh 500Kbps (or less) at weekends.

As an aside...
In response to my request to move back to BT Wholesale, this morning I was sent a migration code.
1) I never asked for a migration code.
2) How can there be a migration code if the line is still LLU?

Sean

Technical Ben · Oct 18, 2011, 10:17:37

Ask/Wait for a reply. It might be the old system sending out requests when applied to the new system.
For example, the old system was to send out mac codes when ever one was requested. As your moving internally, it might just be the old system is sending you the mac code meant for IDNet's internal team. At a guess anyhow. They should be able to clarify soon.

Simon_idnet · Oct 18, 2011, 13:01:44

A MAC code is used to migrate from BT Wholesale to LLU and also in reverse. Would you like us to use that MAC code for you on your behalf or, now that your line appears to have stabilised, would you like to monitor it on the Telefonica Wholesale platform for a day or two?

Thanks, Simon, for the explanation.
My misunderstanding was that a MAC could be used only from one BT Wholesale ISP to another BT Wholesale ISP. I thought (obviously wrongly!) that it could not be used for LLU.

One test of an ISP support team is how well it deals with difficult customers. I don't mean difficult as in aggressive and abusive (which should not be tolerated) but difficult as in those like me who are quite demanding and critical even though they have little technical knowledge. During the last few days dealing with me the IDNet support team have passed that test. I apologise for the hassle my impatience has caused.

Since you reset my line to ADSL2+ my connection has remained solid and download speeds have remained pretty constant at about 16.3 Mbps. So I would like to remain on the Telefonica Wholesale platform and monitor its performance, at least for a few more days, to see if the current performance is maintained, especially through busy weekend times.

Thank you

Sean

Technical Ben · Oct 18, 2011, 18:19:18

Glad to hear it's sorted SSK.

I think we can all "test" the systems at times. I wonder if I could get paid for official testing.

Just in case anyone is interested...
The connection is still solid with speeds steady just over 16.3 Mbps.

Attached is a graph of speeds before and after the problem.
The connection was steady for weeks at about 15Mbps, then on Sat late morning dropped down to about 500Kbps (as low as 190Kbps) until early Sunday. Looking at the sudden big drop, maybe my dismay was understandable?

You can see where Simon put me on ADSL2 (graph jumps up to about 10Mbps) on the Sunday and then to ADSL2+ (late Sun/early Mon?), when it jumps up to 16.3Mbps, where it has remained since (fingers crossed!).

Lance · Oct 20, 2011, 10:58:47

Good to hear it is still working well
