Hi im currently with plusnet broadband and am suffering with slow speeds,i know i pay for up to 8mb but when i run the speed test i only get 1504kbs so thats not even 2mb :(

any ideas on how i can improve it>?im using filters and the main socket

Even though you pay for 8MB, you line may only bae able to provide far less. I pay for 8MB and only get around 2MB, but due to my distance from the exchange it's as good as it gets. Unfortunatley if you read the T&C's of your provider theres nothing you can do unless you can prove some kind of fault with the line or service.

can you get cable?

i dont undersrand why we havnt all got real fast connections in 2008. The technologys there to make it super fast. I think our taxes should go on sceams like that.

Cornish, the answer is simple - copper wire is the reason speeds are not higher. Most exchanges are connected to the network via optical cable but the line from the exchange to your house is likley copper or similar. ADSL allows decent speeds over older cables but the longer the distance the worse the connection.

Unfortunatley the UK is lagging behind in upgrading it's network.

The broadband sales technique, like all many other sales technique these days is to catch out all those whose English is sub-standard: like 50% of people who don't get GCSE pass mark. Broadband is an UP TO speed and is not even committed and with no service level agreement. Another phrase that most people don't understand is the : lowest unique bid, it is the word "unique" that a lot of people don't understand. The two key factors which drives the actual speed down is:-

1) distance from you to the telephone exchange, the further away the lower the speed
2) Contention ratio, broadband means shared bandwidth. A contention ratio of 30:1 means that for an up to speed of 8 Mbits you get 8 mbits divided by 30 at peak loading. An 8 Mbit fully committed leased line in both directions (up and down) is usually at least £10,000 per year charge. So for a broadband of a few hundred quids a year you cannot expect to get service of a £10,000 8mbit /s leased line.
3) The quality of the copper wire and where you are connected to the exchange, you can have a less good wire connection.

In general in UK, people have the mentality of a shoe string budget and we are a proud nation of achieving a lot with the lowest resources. We always admire the David versus Goliath attitude. So here is abroadband service with a bit of a wet string and you can go mega speed at up to 24 Mbites/s for £6.99 and keep our figures crossed! However I think in general the BT offers the best overall service for the money.

The weakest link for home users will always be the tail circuit. The bit of wire that goes from the exchange to your house and all Broadband above 8 mbit is subject to survey.

I think to cover the whole country with fibre optics is around £50 billion. Last time that I did costings for laying fibre optics cable was £1m per mile inclusive of digging and road safety alternatives (or was it kilometer). So the technology is here but £1m a mile is a tough cookie.

Splender I disagree about BT, in my opinion all BB providers are offering similar service save a few bells and whistles. The only difference is price and customer service, personally I pay about £5 per month less than BT and recieve EXCELLENT customer service from a UK based call centre staffed by people who actually know what they are doing rather than reading from a screen.

BT in my experience proide a perfectly acceptable service but when things go wrong you are in for a torrid time.

Firstly, I hate BT, they are totally imcompetant but are unfortunately the only provider for my area.

Prior to getting our internet service from O2, we were sharing our neighbour's wireless which was giving us 4-5mb on an 8mb service.

After getting our brand new BT cable laid and connecting to O2, we only get speeds between 1-2mb - O2 insists there is nothing they can do.

It is highly frustrating as we had to pay £125 to BT for the initial work, £11 per month for the phone which we wouldn' t bother with if it wasn't for the internet and £7.50 per month for the internet service but we were better off when we weren't paying anything!
#10
I'm sure all the contracts state that could you get UP to 8mb, unfortunately.
#11
what is your uplink speed? check your router not a speed test site.
#12
I paid for 24mb once but I get only 2-4mb. I now pay for 8mb and I still get 2-4mb (that's megabits). The line quality is definately the factor here, so you can't really blame it on anything. You could try and mess about with tweaks and stuff, but tbh, the effects are minimal with time involved as the default is already quite good. If you really want 8mb, go optic fibre, like Virgin, though their customer service is less than good. Location is also another factor, as people pointed out already. I think you are just unlucky on that one.

Ever tried using the test socket (the one behind the main one)? Using that will give you the maximum the line can give, if we are not using tweaks. Again, if your line is good, then nothing much can be done.

As for internet providers, some of them are pure absymal, like Tiscali and Orange. Im guessing here that your provider has a good quality of service. If not, it may be a good consideration to change (im with Be, though O2 is likely to be my next provider).
#13
this is what plusnet member just told me-

Looks like you have had line problems and BT have increased your target SNR (noise margin) to 15dB (from 6dB) meaning your sync rate is much lower than previously.

You need to raise a speed fault with PN via http://faults.plus.net and ask for your target SNR to be reset back to 6dB.

An IP profile of 1500 more or less correct for the a DS sync rate you have - it should really be 2000.
#14
I improved my line from a steady 5.5meg to a quite impressive 6.4mb on rate adaptive ADSL today. I'm 3km+ from the exchange. Line attenuation was 49db's now it's 42. BT is rolling out ADSL2+ (upto 24meg)in bigger exchanges from the 21st of this month.
#15
What have you been playing with now Paddy? :-)
#16
Line Length, cable type (copper, ali, lead) and thickness all play a part in the speed you get, internal wiring can also cause big problems, but you appear to have eliminated the internal wiring by plugging direct into the master socket.

Found a shorter, thicker cable to the cabinet that serves my house. Result!

What a result - Nice one!!!!
#19
could that be the problem why my conection drops like every 20 min or so?

Mine on a bad day! I can push 60 meg download and about 20 upload(though never used anything that used that)
#21
Being an engineer does have one or two advantages, only looked for one due to BT finally rolling out ADSL2+, so I should really start seeing some benefits there, well until they throttle me down dueing peak hours as usual. But for free you musn't grumble
#22
strobez - not sure what could be causing you problems without some more information from your router - line noise, attenuation, errors etc
#23

Any noise on your voice line? Your Router actually drops synch and retrains with the exchange? or your wireless drops out every 20 mins.

Absolutely - good work fella!
Regarding the throttling... you could always defect to $ky!! as you now have the same line stats - 42db as me, you could expect a sync of between 7.2 and 7.6meg and no throttling or traffic shaping (and unofficially, no caps!!)

But still, all in all - good job man!! - I bet you were pretty pleased with yourself for finding that one!!!! :thumbsup:

Never heard of the CP, just looking at the website.

well suddenly i could be browsing the net etc then suddenly it wont let me goto another page and messenger live signs out,after a few min it reconects and everything is fine again

Chuffed to bits, we have some tools that look for this sort of stuff. I always assumed I was on the shortest cable with the synch speed I already had due to the line length.
Can't defect, my broadband is free so even sky's £10 a month (cheap as it is) isn't cheap enough.

Log into your router and look for the line up time and how many times its dropped synch. Your in your master socket? Is there any noise on your voice line? (crackling, humming, overhearing).
#30
ok strobez - i'm no expert, but you are quite far from your exchange, hence the low sync speed, however, i think as you are showing a noise margin of 15db, it looks a s though your line may have been capped - possibly to overcome errors on your line.
Your errors as they are are reasonable, but again if your line has been capped - this is as expected.

Do you have a lot or any extensions that run off your main BT socket? and when you say you are plugged into the master - do you mean the faceplate or the test socket behind?
Paddy - shouldn't trellis be set to 'on'?

shhhh! but i'm on the £5 a month one and no cap! - but I take your point - free broadband is always better than paying for it!!!!

sorry I missed them earlier.
#35
when did you lat turn off your router? just for the re-synchs. You've held synch at the moment for just over an hour. That sound right? No problems in last hour?
#36
yes it cut of a few min ago
#37
post your router stats again please (new ones)
#38
I'd guess that you have other extensions off of your main Bt socket and either a piece of equipment and/or some bad wiring is causing intermittant interference and line errors that result in a drop out and re-sync.
If you do have several extensions - check that each piece of equipment has a filter on it including sky tv receivers, if you are out of contract, disconnect the phone lead from sky receiver altogether.
Check to see if plugging into the test socket results in a continuous period of no drop -outs, if so it's pretty definate that your internal wiring is to blame. - If this is the case, there are a few simple tricks you can do to sort it out...
#39
ok,all im suing is the filter and that just has the phone pluggedinto it and the router
#40
are there any other phone sockets in the house that use the same phone number?
the BT socket - is it the new style one with a horizontal line half way up it?
If so, are you plugged into the front plate or the 'test' socket behind the front plate?
