Slow broadband downstream line speed [ Edited ]

[MPR]

With slow broadband speeds I have had lots of input from BT.  Most recently, on Tuesday I had a "broadband boost" engineer come out who made sure that the line speed coming into my house (3.5Mbps - high for around here) matched what was registering as the downstream linespeed on my router.  Hooray!  After the magic he worked (connecting to main socket, getting rid of dodgy phone extensions etc etc), I now had 3.5Mbps coming into my house, and the router in the house suddenly connecting at the same 3.5Mbps for the first time.  I couldn't wait until the IP profile and broadband speed came up to match.

Not so.  Since the success on Tuesday, the downstream linespeed showing on my router has steadily dropped from 3.5Mbps to the point where it's Friday and now at 1Mbps.  That makes me think that instead of increasing my IP profile to match my downstream line speed, and giving me faster broadband, BT's systems have instead somehow 'choked' or reduced the line speed coming into my house.

Does anyone know how I can get BT to increase the line speed back up to the 3.5Mbps it was earlier this week?  Can they flick a switch somewhere?  I am hoping that if they set the line speed higher then my IP profile and broadband speed might start to drift upwards as well.

Does anyone out there in forum-land have any clues about this?  I've done a lot of reading on the internet and on the forum but am yet to find something that helps.  What I want to know is whether they can increase the downstream line speed coming into my house.  1Mbps on Friday seems pretty darn slow when it was 3.5Mbps on Tuesday...

Thanks in anticipation...

Hi can you please post your full hub stats and a full Bt speed test to get hubstats enter 192.168.1.254into your browseraddress bar and navigate to broadbababd an connection and the speed test speedtester.bt.com then some one here can help you

Recent tests have been confirming the downstream and upstream below.  IP profile is 1Mbps, up from 750kbps earlier in the week.  Broadband speed this afternoon is about 800-900kbps which is the best I have had since Tuesday.  At the same time downstream line speed has plummeted from 3.5Mbps to what you see below.  That drop is what's confounding me.  Sorry but I have to wait for an hour to do the test again but above tells you what it has been doing over the week.

Hi your connection speed has dropped due to hub disconnections this has increased your noise margin from the default 6 to 22.9 the forum mods can be contacted to reduce thisback to the default level however you need to find the cause of the increasefirst first tou could trythe quiet line test dial 17070 and select option2 no noise should be heard any noise heard should be reported to Bt faults on 151 but do not mention broadband when you call
Once you have maintained. A stable connection for 3days you can contact the forum mods at this link http://bt.custhelp.com/app/contact_email/c/4951 they wil reply to you directly by email or phone normally within 72 hours they are uk based specialists

Do you think the 72 hours is 72 'real' hours, or 72 working hours?

the 72 hours is not fixed but just a rough guide - just need to wait but if in doubt send another email

[MPR]

Do you know whether they send an acknowledgement email once the query has been submitted (because I never had one of those)?  That's what has had me wondering whether the query has gotten through...

[MPR]

Have just heard from mods.  They tell me they have ordered a re-set of my hub - so that part of the process looks to be working!

You must have friends in high places...

[john46]

hi no the mods are just a team of UK based BT specialists who deal with this sort of issue daily as to an acknowledgement that is the series of numbers displayed on the screen after you post the link something like 111-2333554455

Mods told me they would order re-set.  After a few days noise is still higher than the default (we had 1-2 power cuts) but, as a result of the re-set, noise has indeed reduced.  Downstream line speed has increased.  IP profile has increased.  Download speed has increased!  From I think 400-800kbps previously to 1,800kbps now.

That counts as success - thank you.  Ordering the reset from the mods (which eventually got noise down, eventually line speed up, evenutally IP profile up) has doubled download speed from unacceptable to pretty much acceptable for our neighbourhood.

Thank you!
