Painfully Slow NETSpeed .. ADSL issue?

I have been experience really poor connection with the internet these past few weeks (about 2 if i recall it began) I am on a 8MB ADSL with Xilo internet.

I have done some speedtests @ speedtest.net

I got:
1.05 Mbps Down (bits not BYTES)
0.05 Mbps Up (bits not BYTES)

Prior to this issue i got arounf 7.2Mbps Down and 0.5Mbps Up.

I have tested it throughout the day on all my PC's i have (3 in total) and i get the exact same connection speeds on all.

I have done some check of my sync speeds which appear to be my usual fairly good conenctions:

Modem reports:

DSL Status: Connected
DSL Modulation Mode: G.dmt
DSL Path Mode: Interleaved
Downstream Rate: 8128 kbps
Upstream Rate: 448 kbps
Downstream Margin: 12 db
Upstream Margin: 25 db
Downstream Line Attenuation: 36 db
Upstream Line Attenuation: 10.5 db
Downstream Transmit Power: 12 db
Upstream Transmit Power: 5 db

BT Speedtester Reports:

Download speedachieved during the test was - 6084 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps

Anyone got any advise as i don't quite know where the fault is now.. :(

It would seem your not alone, I too am with Xilo on their 8mb Home 50 package, but for me its been the slowness of web browsing thats my problem.

Like you its only been noticable over the last couple of weeks. Xilo have since said to me that they think the fault lies within my own small network, congestion they call it, whatever that means. To be fair though Xilo have been great, and it may well be that my issue is indeed with my own setup. But having said that, nothing physically has changed in my setup, so a lot of head scratching here too.

Funny thing is I'm now in the process of going over to their Pro 16 office package, come Wednesday, so it will be interesting to see what that does to everything.

I am running a Billion 7800n which I've used since early last year, and has been rock solid. Someone has suggested it might be down to DNS servers, but I'm already using ones that come up top in DNSBench.
 
Hmm that sounds a bit fishy then. There tech support have basically stated that the 6084kbps i got from BT is within reaonable limits, however i dont get that sort of speed from any other site. All my downloads no matter what site seem to go above 150KBps and the upload is painful..

What should i do? (strangely i was temptd with switch to there Pro 24MB package but later cancelled due to the £40 LLU migration cost.)
 
The BT tester is a good tester, on a good network with plenty of capacity unlike some flash-based or free test sites, also, it works better with machines that have anti-virus/malware scanners on that can affect flash-based testers quite severely.

There is nothing special about the BT tester though, it is a standard download that is logged to BT's database in case of a real throughput fault, such as with a congested VP. You could also test the throughput by logging in with the BT diagnostic login. If this also gives the same throughput, the issue isn't the line, or connection but without a doubt, something local to you (software?).

I'd like to assure you that there is no congestion in our network.

Earlstreetblue: The issue you reported to us was inability to open pages at all and when you did, they were slow. This can be indicative of a local issue or setting mis-configuration (DNS, MTU etc). Also, the CPU in most home ADSL routers isn't very powerful. If say, there is something on the network that has a lot of open sessions, i.e if you're using NAT, this could also prevent pages being opened or even slowness.

Thats because the other sites will be going on throughput and currently your ADSL profile will be way below your Synch (connection) speeds shown above.

Your own "small network" will not cripple your BB to an unuseable state unless somethign is saturating your UL.
 
While I appreciate BT is probably a more accurate test of my down speed it dosnt test for upload. While speedtest.net isnt a very good site i would expect some reasonably close figures.. 1mbps vs 6mbps is a bit of a jump.

Does anyone know of a good UK site i could try a file download from that should potentially give me a good estimation?

I personally think the poor download speed is a result of an even worse upload speed. The best upload I can achieve on speedtest.net is 70kbps (yes seventy) which is fractionally better than a 56k modem.

you may not like the £40 LLU costs but that would *probably* go a long way to solving your issues. For starters your upload speed would increase greatly...and you'd be away from BT's network which could be causing these issues

Very true.. But it seems silly to spend money fixing a problem I didn't have 3 weeks ago and nothing at my end has changed. Although obviously if this is the only solution I might just have to :(
 
If it's congestion on BT's network in your area and they might have signed a few up over the last few weeks then there's nothing that you did or can do that will alter your speed apart from moving away from them. Xilo are pretty good, and to my eyes their LLU packages are far better than what your on now. But the crunch is that they have far more control when you're on LLU than they do when you're on BT. They can push the boundaries more, get a better response if there is an issue and also control it far more with regards to congestion etc. I'm not against BT at all, but they are the ISP for everyone, as in they pretty much have to cater for everyone and this does result in problems. I've recently moved to LLU and it's like night and day

OK Ive done the thinkbroadband speed test as well (Java based) and got:

Speed Down 1239.82 Kbps ( 1.2 Mbps )
Speed Up 66.95 Kbps ( 0.1 Mbps )
Port 80
Server speedtest2.thinkbroadband.com


I then did the same test on port 8095 and got:

Speed Down 6050.45 Kbps ( 5.9 Mbps )
Speed Up 341.38 Kbps ( 0.3 Mbps )
Port 8095
Server speedtest2.thinkbroadband.com


So it looks like my issue is related to port 80? .. (and possibly others)
 
port 80 *should* be your http server, have you been running a server at home? it is also external webserver's normal ports...

I very much suspect you have something running on that machine that is scanning in/outbound web requests, as advised earlier.

Using a non-standard port will generally mean software can miss that data. We've got a new java based test we're trying. If you drop us a ticket, we'll give you the URL for it.

I havnt got any web servers running.. on this or any of my machines. Just basic windows 7 installs with a few basic apps.

I post a ticket for the new java based test.
 
This might be related to my QOS settings.. i have just disabled it all and now appear to be getting a much better speed on port 80. I didnt think QOS affected speeds only latency based on packet priority which is odd..
 
QoS will affect any services that are defined within the rules on the device.

As your router may have not been applying QoS based on packet type but simply destination port, this could be why throughput on other ports were OK.
