What sped should I expect - newbie question


[link to this post]
 
I changed ISP in November 2010 and now get a constant 2.3 / 0.8 whereas with my previous ISP I got up to 4.5 though it fluctuated a lot.

I have managed to find the following

BT Speedtester

Download speedachieved during the test was - 1959 Kbps
 For your connection, the acceptable range of speedsis 1200-4000 Kbps.
 IP Profile for your line is - 2500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 10.54:23.6:65.85 (SBE:NBE:PBE)

and from my router


noise margin upstream: 5 db
output power downstream: 0 db
attenuation upstream: 26 db
noise margin downstream: 13 db
output power upstream: 12 db
attenuation downstream: 42 db

I don't understand the figures but I would be obliged if someone could interpret them for me.

Thanks in anticipation.

you missed a bit from the BT speedtest I think, mine says

Download speedachieved during the test was - 2269 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :7616 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 6500 Kbps

(my italics)

attenuation downstream: 42 db should see you connect at ~6M or so. Is this measured in the test socket behind the master faceplate ?

Thanks for your reply

Full results from speedcheck are:


Test1 comprises of Best Effort Test: -provides background information.

Download Speed
2422 Kbps

0 Kbps 4000 Kbps
Max Achievable Speed

Download speedachieved during the test was - 2422 Kbps
For your connection, the acceptable range of speedsis 1200-4000 Kbps.
IP Profile for your line is - 2500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 9.78:24.79:65.43 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.


If you wish to discuss these results please contact your ISP.

If you are experiencing problems with specific applications, servers or websites please contact your ISP for assistance.

Your test has completed please close this window to exit the performance tester.

Note: An Upstream test was not conducted on this line due to a technical issue. If your concern is related to upstream performance then please retry
the performance test again in 1 hours time.

Please visit FAQ section if you are unable To understand the test results.



I presently have the router plugged in to the main socket, I have tried it in the test socket with no change of speed shown. I have tried different filters and a different modem.

Thanks

John

the speedtester isn't returning your sync speeds, can you get them off the router plse downstream / upstream speed.

The speedtester says

For your connection, the acceptable range of speedsis 1200-4000 Kbps.
IP Profile for your line is - 2500 Kbps

which is a bit odd as 4000 is obviously faster that the profile of 2500 would permit.

Is this what you asked for?

Interface Status Rate
DSL Up 3065 kbps / 1012 kbps
LAN Up 100M/FullDuplex
WLAN Active 54M

DSL Up 3065 kbps / 1012 kbps

that's the one. This says you have a 3M link to the exchange, which has got you a 2500 profile which should speedtest at about 2300. Which is about what you got on the speedtest.

When you tried in the test socket did the above numbers stay the same, or the speedtest ? We wouldn't expect the latter to change due to time delays in the IP profile system.

Not sure. I'll connect to test socket and check

keep an eye on
noise margin downstream: 13 db
too, see what it is just after reconnecting.

Router now connected to test socket:

3065 kbps / 1009 kbps

noise margin upstream: 5 db
output power downstream: 0 db
attenuation upstream: 27 db

noise margin downstream: 19 db
output power upstream: 12 db
attenuation downstream: 42 db

as you say, the same. Was only the router plugged into the test socket ? are you sure there's nothing connected to the line before the test socket ?

On the face of it the noise margin downstream: 19 db is 6dB higher than before and this suggests the speed is being capped and not following the extra available signal upwards.

I'll ask RobertoS to take a look as he has more experience of 21CN profile options than me.

Yuo could ask your ISP - who is the current and the old one ?
