Re: Single thread congestion.


[re: professor973] [link to this post]
 
Update ... The single thread episode was short lived. That said, my connection went mental just after midnight. Disconnections every minute or two and speed flapping up and down like a see saw. My thought then, was to revert to the BT approved Zyxel AAISP supplied and configured router, despite how bad it was initially, especially as I may have a so called SFI turn up - A couple of re-syscs on from that, my available speed jumped up 13Mbps to near 66Mbps - about 2Mbps short of the 68Mbps I had initially last time I had FTTC. Also, wonder of wonders, it has stayed stable overnight. Obviously some auto adjustments overnight and wonder if G.INP has been applied, though my minimum latency is about the same. Either way - Fingers crossed and leaving hardware well alone for a while.
This apparent DLM brainstorm has been the problem all along with BTW services. To my mind, if DLM decides because of errors, noise ot whatever to slow things, surely it should keep things at that new speed for a while - Not keep flapping up and down every minute or two by many Mbps. To my mind, it's a cab/exchange equipment problem. A view that was shared by Pulse8 when with them. But suggesting changing a line card or whatever at the exchange sends OR engineers ballistic. Apparently it needs special dispensation from somewhere deep within the bowels of Openreach. Anyway - image of after midnight adjustments. The fact that the far higher speed is holding, suggests to me no serious noise on my line.

I've recently switched from the OR supplied HG612 to the AAISP supplied ZyXEL. I was getting a resync most days with the HG612 (I know what it was - the central heating hot water reaching the correct temperature). I'm not getting any with the ZyXEL so that suggests the ZyXEL is good at holding sync.

Can I suggest you download and run DSLstats which will record and give you graphs of how the connection is running: http://www.s446074245.websitehome.co.uk/index.html

The SFI that worked on my line a few years ago had full authority to enter the exchange and work on equipment there also - the job took several hours and he kept me fully informed, via mobile phone, about his checks at the cab and the work at the exchange whilst the line was down.

Please be patient and keep the A&A supplied modem connected to the test socket continuously.

Only problem with the supplied AA router. The second you plug it back in, G.INP straight back on - Stupid high speeds, errors and re-syncs make it unusable most of the time.
