Can you perform the speed test per these instructions and find out what your IP profile is?

Can you perform the speed test per these instructions and find out what your IP profile is?

http://www.kitz.co.uk/adsl/btwperformancetest.htm

After switching to using IE and opening the port up on the router, i got this.....

Download speedachieved during the test was - 5760 Kbps
 For your connection, the acceptable range of speeds is 4000-21000 Kbps.
 Additional Information:
 Your DSL Connection Rate :16280 Kbps(DOWN-STREAM), 1159 Kbps(UP-STREAM)
 IP Profile for your line is - 14363 Kbps

and

>Upload speed achieved during the test was - 371 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 1159 Kbps

Does this help?

Reply from my ISP, told me run this BT ADSL Availability checker.......result below......Going on this, i'm not going to get any faster 

For Telephone Number 01793xxxxxx on Exchange SWINDON

Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.

Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 7Mbps; typically the line speed would range between 6Mbps and 8Mbps.

Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 8Mbps; typically the line speed would range between 6.5Mbps and 14Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 8Mbps; typically the downstream speed would range between 6.5Mbps and 14Mbps.

Your cabinet is planned to have WBC FTTC by 31st March 2012. Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 40Mbps and upstream line speed of 10.9Mbps.

The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained.

Well you can ignore the availability checker as it's clearly telling porkie pies when you have an ADSL sync of 16Mbps and an IP profile (which means your sync has been stable for some time) of 14Mbps, so don't let them fob you off with that one!

Basically, though, the IP profile says the DSLAM has detected that your line is stable enough for 14Mbps, if it's going slower than that then it's either your router/modem, your ISP or the speed tester itself - you've ruled out the speed tester by using the BT one (which agrees with your other test) and you've ruled out the router, so.. that leaves your (crappy, sorry) ISP..

It's also saying you have an upstream IP profile of ~1Mbps but you're only getting ~0.35Mbps - that's outgoing traffic speed.

Personally I imagine PlusNet are rate-shaping your line - last time I looked at ADSL connections they were well known for doing that (one of the first ISPs to buy in large quantities of rate shaping equipment, IIRC) - i.e. artificially lowering the speed you are able to achieve.

Lappy is connected using 150M wifi.....

Modem connection speed has dropped slightly since ive just set the modem to force an ADSL2+  connection, it was set to auto....

That low margin isn't going to help on the throughput stakes TD, most routers struggle to even hold on to the ADSL signal below the 6db mark.

Can you go to http://www.samknows.com/broadband/exchange_mapping and tell us what your estimated line length is please.

Can you not just get fibre optic -if i could i would!

1491m apparently

Had this message back from my isp.....

Thank you for getting back to us. I have checked and found an issue with one of the profiles on the line. I have arranged for this to be corrected and your speed should be available within the next hour.

If you are still having issues after this please get back to us.


I cannot connect to the bt speedtester atm, so will try early in the morning (Sun evening not being the best time try speedtests)

However, i did try speedtest.net and theres definately an improvement...



Again not the best time of day to test speeds......will try this again in the morning...

Your line length and current stats aren't that far off mine when I had ADSL2+. My line was slightly shorter than yours, had a slightly higher noise margin, and I used to regularly sync around the 15,500 to 16,500 mark.
My real world throughput when downloading single large files (eg, Win XP SP3 network install version) from MS was always around the 14 Mbit (1.5 Mbyte) per second mark, so I'd expect to see at least 12 Mbit based on the stats you have posted so far once they fix the fault.

As the sync is OK, speedwise (though the SNR being low, I'd expect this to drop off slightly), I'd put it down to a poor ISP TBH.

If its a BT Wholesale provided product, try changing the router to use the BT Speedtest credentials, and using the BT Wholesale speed tester, as this will bypass your ISP.

Log in to your router and change the username to speedtest@startup_domain (the password can be left blank), then go to http://speedtester.bt.com/

Thankyou, i'll give that a go and post the results up

This didnt work.....i changed the router login details......it just sat with its red light on.....the router didnt get an ip address or dns settings.....i gave 1/2hr ....then changed the login details back.....

In which case I'd guess you're LLU'd, so its just a shite ISP
