In theory then you should be able to acheive 8Mb (and more) without any problems.
In erring on the extreme side of caution and that even if your line goes all round the houses and the length is double that.. your attenuation would
maximum be around 15dB.
Market 1: BT Wholesale is the only Market Operator
Unlikely then that youre on LLU... so either BTw IPStream or DataStream - dslmax
BT Line Speed Estimation:
Fixed ADSL: 2048 kbps (2 Mb)
DSL Max : 8000 kbps (8 Mb)
You should have no problems in your area getting the 8Mb.
Have you tried the
test socket to see if your connection speed is any better from there.
I can't actually pull up my line stats as of recently as I'm using the latest ST330 drivers
The ST330 can sometimes be a bit tricky to get stats from.. and it quite often will throw an error message. However despite the error message it still often provides the stats to a text file.
The ST330 sometimes has problems with maxdsl.. but if you are using the latest drivers then you should be ok.
I actually rang Virgin and spoke to them about the max capped rate and the guy on the phone seemed very evasive and said he'd never heard of it and didn't have any clue what it was.
As mentioned above - this seems typical for some of the larger ISPs
If they read the BTw Max Customer Handbook, then they should realise it is entirely possible to ask BTw to put you on either:-
~ BT IPStream Max Capped Rate Profile 2000 or
~ BT DataStream Max Capped Rate Profile 2000
These newer products are the maxdsl equivalents of the old fixed rate products.
Its also mentioned in BT SIN 485 page 16 - where it tells the ISP how to request this
However.. before doing that I see no reason why you shouldnt be able to get the full 8Mb and theres something else stopping this.
The latency spikes are worrying me indicating possible EMI interference -> high error rates.
Although saying that Virgin IPStream DSL sometimes has its problems with congestion on their centrals.
To be perfectly honest we really need to see linestats to find out exactly just what is happening.
Is there anyone that could lend you a router for a couple of days?
... Alternatively.. ask Virgin is they can arrange a WOOSH test for xDSL status check.
If they are co-operative they may give you the results.
