View Full Version : Download speed slow
Just done a BT speed test to check my ip profile an my download speed is half of what the profile is:confused: (see below)
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 4000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 4000 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1841 kbps
I have chech to see which pipe i am on and its green with 7.2mb so thats ok what could it be:rolleyes:
If it's the same problem I've had twice in the past couple of weeks it's an Enta radius server problem. To verify, you should do the old BT test as well and check the discrepancy between speeds from the new and old tests. That discrepancy is down to Enta, and you can raise it with Brian.
Ircsum.
whats the old BT test:confused:
You'll find it here (http://217.32.105.42/cgi-bin/home.page.pl).
You need to disconnect your ppp session, login as speedtest@speedtest_domain, no password, then surf to the link above. It bypasses the ISP so removes them from the equation.
Ircsum.
Thanks mate:D Just tryed it connected to internet ok clicked on link ok but when i put the phone nunber in and click go after 30 secs it comes up with page cannot be displayed:rolleyes: i am using IE7 tryed it a few times still the same
It was working this morning...I'll give it a go (Firefox) and report back.
Ircsum.
edit: Yep, works fine with Firefox.
Its intermitent, keep trying.
Just worked for me on IE7
2507kbps :eek: , need to put a new rubber band in my router :D
Tryed it again but would not even log onto bt web address so i will give up tonight as it is valentines night;) But checking on www.speedtest.bbmax.co.uk/ my download speed is now about 3500kbps. Which i think is correct for a 4000kbps profile. Maybe it was congestion on my exchange, as it has been in the red since november (but BT love to keep moving the eta times for fixing it:rolleyes: ) Thanks again for the support i will keep a eye on it:D

One thing I've started to notice is that when I disconnect then reconnect I get good speeds of 4-5000kbps, but within an hour or so it drops back to below 2000kbps again. On checking my test history the only time I get high spikes is when I've re-connected, but other than that it only ever achieves 1600-1900kbps.
I know I'm still in the training period for a few more days, but is this normal activity?
Yeah. To be honest I have noticed a different in BT speed test results and thru-put on enta. There seems to be 25% difference, roughly.
"Houston, We may have a problem"
The problem seems to be a side effect of the anti-loss tool. When the pipes go green the d/l speed will stay stuck unless you disconnect & reconnect to a different Central. It's a radius/anti-loss tool issue.
Ircsum.

Same again this morning, tested it when I turned PC on and it was 1790 - re-connected and it shot up to 5930 - will test it again in an hour or so and see if it's dropped again.
I think I'm on last day of training today, so will see how it goes over the weekend.

That shouldn't happen though. Has anyone reported it to Entanet?

They seem to be vaguely aware of the problem, from what I read on the AG forums.

Just tested speed again after being connected 4 hours and I'm pleased to say it's stayed up! :D
Results taken from speedtest.net just now ...

I just did a speed test and this isn't very good at all:

I'm suppose to be on a MAX product here!
You was connected on the 13th Feb.
Your inside your 10 day training period.
Broadband Max points to note
Please read the following carefully:
Broadband Max is a RATE-ADAPTIVE technology that can provide connection/download speeds of UP TO 8Mb (8 Megabits) per second.
This may mean that you will not receive an 8Mb connection when you re-grade to Broadband Max.
Broadband Max works in the following way:
BT software at the exchange level initially determines the MAXIMUM possible connection speed that can be achieved for your line. This depends on many variables, including but not limited to, line quality, distance from the exchange, and exchange capacity.
WE CAN NOT SUBMIT ANY FAULT REPORTS TO BT RELATING TO SPEED ISSUES OR DROPPED CONNECTIONS DURING THIS 10 DAY PERIOD.
Once the training period has finished, your MSR does not guarantee that you will connect and achieve the MSR at all times. As mentioned previously, Broadband Max is RATE-ADAPTIVE PRODUCT, this means that more or less bandwidth will be available and allocated as the controlling software at the exchange determines.
Again, if your connection and speed falls within BT's Acceptable Parameters as determined by your MSR, WE CAN NOT SUBMIT ANY FAULT REPORTS TO BT.
What causes loss of sync?
Generally, noise, RF interference and noise from local electrical items are common causes.
Is it SNR dropping below a certain value? (http://adsl24.co.uk/faq.html#21)
Yes, once your SNR/noise margin falls to the point your router struggles to differentiate the ADSL signal from the background noise, it has no option (other than disconnect and try a re-sync, usually resulting in a lower sync speed).
What can I do to stop it happening?
Try the steps mentioned here (http://www.dslzoneuk.net/socket.php?type=html). BTW. It's not ISP related. Any increase in the number of re-syncs occurring after a migration is usually down to other factors:
1. Have you changed from a fixed speed product, to ADSL max (ADSL max, by its very nature, results in a lower noise margin, and increases the risk of instability)?
2. Were you on a LLU product with your old ISP (which would involve moving your line to different equipment in the exchange)?
3. Are you using a different modem (or router)?
4. Have you added any new items to your 'phone setup?
5. Have you, or your near neighbours, recently installed any new electrical appliances?

Your results will be all over the place for the next week or so OldPing, until you finish your training period, mine have been too :)

How come your upload is so high Brian?? :eek:

Yeah. I'm not too bothered anyway at the moment. Just having a connection after the 186K experience is a luxury!
That response from 'Brian' looks like hes copied and pasted that a few times. :p
I did a BT speed test too just after, it said:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 2000 kbps
DSL connection rate: 288 kbps(UP-STREAM) 1152 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 623 kbps
Interesting why throughput via the actual IP address is so slow isnt it.
Because Im on a business package.

Well Brian i think something is not working somewhere on the Enta network as i have just done a speed test (see below)

IP profile for your line is - 4000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 4000 kbps(DOWN-STREAM)

Just disconnected from internet and reconnected and tested again (see below)

So there is a problem there but what is it:confused:

It hasn't happened to me today though, and I'm on Day 10 since migration.
I've done several tests throughout the day and have consistently achieved a stable speed of around 6000kb/s but prior to this I could only get the higher speeds shortly after re-connecting before it would drop off again.

I don't think it's affecting everyone. There are reports of the same issue on other forums.
I migrated on the 13th from Aquiss

The issue with needing to disconnect and reconnect to get maximum speed affected me this morning.
Brian - do you know whether Entanet are looking at this please?
tboorman
16/02/2007, 13:37
Any chance you could raise this with them please? Do you want me to open a support ticket with you about this?
Send a support ticket to support@enta.net or us and I'll see what I can do.
Give as much detail as possible so everyone understands ;)

The issue with needing to disconnect and reconnect to get maximum speed affected me this morning.
It happened to me too, I was down to around 1700kbps when I logged on this morning, re-started and got 5900kbps, but just checked again and I'm back down to 2094kbps :confused:
I had it on TH2 yesterday. Last night I was on Global Switch and speeds were fine this morning. It may only be affecting TH2.
Ircsum.

I had the problem on Global Switch this morning.
You saw the 'balancing' answer given at the other place, Tim?....early in the morning that can't be an issue, surely?
Ircsum.

It was at 6:15 am, so it can't be anything to do with the centrals being out of balance. If it happens again, I'll raise a support ticket about it.
If I were the suspicious type I'd speculate that Enta were damping daytime throughput in a random way, until capacity increases a bit. A ticket might get the response that there's an incorrect profile setting on their radius server, and they'll fix it. Just as well I'm not the suspicious type. :)
Ircsum.

Dropping the PPP session and reconnecting fixes it though, so I don't think it's deliberate.
I suppose I'm basing the suspicious viewpoint (which I don't hold, of course) on the slightly dismissive 'balancing' answer mentioned earlier.

The same thing happened this morning on TH1 - my download speeds wouldn't go above around 280 KB/sec. Reconnected to TH1 again, and hey presto, my download speeds were back to 375 KB/sec.
I've stayed on GS....didn't have the problem yesterday morning & didn't have it this morning, either.....750-770 KB/sec down, about my max at present.
Ircsum.

I switched to TH2 last night and it's been fine since, no major drops :)
