Just ruled out the modem and router as they work fine at a mates a few doors down, his did not work at mine however.

They dont all do that though. A friend recently had an Infinity install and the guy just used one of the rehukar speedtest sites. He's now having to run the gauntlet of BT customer services as the speed has never been greater than about 8Mbits with a 38Mbits profile even using the BT Speedtester.

When we got ours installed last July by one of the "first fttc engineers" (the engineers own words) he just used speedtest.net.

Needless to say it was fast then and fast now.

Could be an internal ISP profile limit, same as mine. One call to the ISP removed the 8mb MaxDSL profile and I was up to full speed - until they disconnected me at the exchange a month later! I think that it may have been a stop/start on my line that caused the problem, phone worked all the time but apparently a cease and re-connect will keep the phone working but drop the data service on that line until put back in place.

Still waiting to hear from the ISP today regarding this but have Wed or Thurs as a fix date from BT - fingers crossed.

ISP finally managed to get some sense from BT. My order was never completed on BT's system and as such, exactly one month after install day, the order was cancelled and subsequently stopped my data conncetion.

Thanks for the useful tips on recovering ties at the exchange and modem failure, but in this case it was a clerical error as the job was never put down as finished. Have next Monday as a provisional re-connection date but senior staff at the ISP are trying to push this through sooner. Modem is still showing green so hopefully it won't require a visit to my house, just the exchange.

Hope I get my 40meg pipe back this week, don't really want another weekend on the 3G!

Engineer came yesterday to re-connect the FTTC connection, replaced the modem as he couldn't get the original one to sync - even though it was sync'd until the day of the re-install.

Sync'd at 40/10 (again) and an initial speed test showed the same as before, 37 down and 8.3 up with ping at 12ms. Great, all sorted. Went to work, came home and ran another test - this time it won't go over 27 down and the upload is stuck at 0.5mb. BT speed tester shows IP profiles at 38717 down 10000 up, but only getting 25 down and 0.5 up so something is choking it somewhere along the way. Each speedtest shows exactly the same upload and you can tell it wants to go way faster.

Pretty fed up at this point, just knew that the reconnection would screw up the perfect conncetion I had before!

Raised with ISP and has gone to Wholesale as they can see something is not right, pings have gone up by a few ms also. All it needed was some paper work doing properly when they did the original install and I wouldn't have the problems I do now.

Just had a further chat with my ISP and got them to run another test on the line, they can see my IP profiles at 38717 and 10000 but the BRAS profile is not showing and was told they would expect to see both profiles on any xDSL connection. I've asked them to pass this on to BTW and ask for them to be manually reset to max.

Could this be causing my 0.5 meg upstream issue and the loss of 10meg downstream after BT re-connected me on Wednesday?

Also not sure about the difference between the two profiles but can see with a perfect sync that something is holding the line back?

Tom

Made some headway on this, ISP phoned twice yesterday to keep me up to date and then to confirm an engineer visit to the exchange first thing Monday. Upload speeds yesterday were still capped at 0.68Mb (on 40/10 product with 40/10 sync), but downstream is now running as it should. Something seems to have changed overnight and would tie in with a 3 day period.

A few tests this morning have shown the upload increase to 1.68Mb and latency has gone back to what it was before BT disconnected me a couple of weeks ago. This seems to be the exact upload that people on the 40/2Mb service seem to get, can anyone confirm this?

I still think that there is a profile mismatch somewhere in the system. My IP profile is still at 10000k upstream but instead of the 677k up I was seeing after the re-connection, I'm now seeing 1690k up, as you would expect for a 2Mb upload profile. How common are profile mismatches between DSLAM and BRAS and does a 3 day period have any affect on changes to these profiles?

Wondering if those profiles cannot be reset remotely and why it would change by itself, unless BTW did something last night.

Thanks
Tom

There is no 3-day period involved here. Profile changes on FTTC are almost instantaneous when the sync changes.

I believe the difference between a 2Mbps and 10Mbps upload is an engineer setting at the exchange, so I think you are right. Instead of correcting it to 10Mbps from something spurious he has set it to 2Mbps. (Edit - Rot, as pointed out by Zarjaz. Also see my next reply to you).

Round you go again it seems.

Sorry to keep harping on about this, but ....
Please ask your ISP what exactly an engineer will be able to achieve with an exchange visit ? Your problem is with, by the looks of it, IP profiles, this is not governed/produced/monitored/supplied/measurable by an engineer visiting the exchange.

After all your hassle, I'd be pushing for a cease and reprovide of port in the FTTC DSLAM.
