Hi Jim.
From the link you gave its shows.
Estimated line speed:
    2.5 Mbps - Checked on 2008-12-13 09:38:06
Current line speed:
    3000
Don't know where the 3000 comes from ,always a constant 2700 ish kbps down.

Re: Download speed

for 3000kbps profile thats about right maybe get 100kbps more thoughput if your runing xp and tweak mtu rwin
the 3000kbps line rate is a profile set so the maxium throuput is 3000kbps but you will see around 2800 max thoughput on that profile.
from the looks of your sync rate thoe you could get a stable 3500kbps profile if you make sure your lines stable and dosent resync and if you reboot router your self make sure you do around midday and not at night.
speedtest on my 3000kbps profile line

theres a handy table on here that tells you what sync speed you need to keep above to obatain which ip profile the table says throuput but should say ip profile in my view

Re: Download speed

That answers the question.
The 3000kbps is the figure from the BT system and is equivalent to the IP profile set by the exchange.
Basically it is a speed restriction set automatically from your sync speed (approx 500kbps below it) and if you have a low speed sync it drops immediately but then takes approx 3 days of constant higher sync speeds to go back up.
For that profile speed your speed test is about right.
For a final check can you run the BT Speedtest http://speedtester.bt.com/ and report the results. This tells you how to do it http://www.plus.net/support/broadband/troubleshooting/bt_speed_tester.shtml

Cheers Jim,so what does all this mean,from plusnet site.
This table shows the maximum possible throughput speeds for the different sync speeds you might see.

from 288kbps up to 0.25Mbps
from 576kbps up to 0.5Mbps
from 1152kbps up to 1Mbps
from 1728kbps up to 1.5Mbps
from 2272kbps up to 2Mbps
from 2848kbps up to 2.5Mbps

Re: Download speed

Those are the IP Profile rates against sync speed which are about 500kbps down
So for a 3000kbps current line speed you must have had a sync of between 3424 and 3999kbps in the last 3 days and to get 3500kbps you would need to hold sync between 4000 to 4544kbps
My stable sync speed is about 3,700kbps which gives an IP Profile of 3000kbps

Re: Download speed

well to keep you ip profile of 3000 you need to keep your router sync'ed at or above 3424kbps and to push your profile to 3500kbps you would need to keep your router sync'ed at or above 4000kbps.
from 3424kbps    up to 3Mbps
from 4000kbps    up to 3.5Mbps
i will bow out now as oldjims wizard's powers can type faster than me

When Jim I'm confused,my synch speed has been for several hundred hours approx 3880kbps,a week or so it went up to 4544 kbps so don't under stand
why down speed has not gone up in all that time of well over a 1000 hrs  of constant connection @exchange.

Re: Download speed

the only answer's to that is your sync rate has a blip every 3 days and drops below 4000kbps theshold and keeps your profile at 3000kbps or you have a stuck ip profile.
iam sure when PN staff pick this up they will give it a poke to unstick it if they see on there data that your line has bein sync'ed higher enough for it to be a stuck profile. stuck profiles do happen a fair bit
how long has your router bein sync'ed at 4544 for?
it takes around 3 days for ip profile to catch up with your new sync and like said before it needs to stay above 4000kbps for the whole 3 days to up to 3500kbps profile

Re: Download speed

Hi ASBO
I check synch speed daily ,as mentioned been synched at 3880 kbps for approx 750 hours and synched @ 4544 for 270 hrs approx.
so plenty of time for speed to upgrade surely.
Thanks for reply .

Re: Download speed

well when PN staff pick this up tomoro they will look to see if you stayed sync'ed at 4544 for past 3+ days and will slip on the hob nail boots and give your profile a gd kick for you.
iam sure jameseh will be the first to get to this thread tomoro. place your bets now Grin

Re: Download speed

Where is the output from the BT speedtest http://speedtester.bt.com/ ? The profile that it is showing is critical. The PN one follows that usually within 12 hours.
I wouldn't recommend speedtest.net by the way, it has proven to be unreliable. If you want throughput testers http://www.mybroadbandspeed.co.uk/ or the one at http://www.thinkbroadband.com/
