only 1meg according to broadbandchecker.com

Hi,

According to Tiscali's site and also verified with broadbandchecker.com, my
line is only capable of 1mb.

I've been with Virgin.net for a few years now and am currently looking at a
phone/BB bundle with Tiscali ( heard too many negative things about
Talk-Talk )

I have to admit , my broadband has never been tip-top for speed, but I did
think it was approx 2mb speed though.

My router adsl typically looks like this :-

Downstream Upstream
SNR Margin 6.9 23.0 dB
Line Attenuation 37.6 27.0 dB
Errored Seconds 2814 85
Loss of Signal 14 14
Loss of Frame 0 0
CRC Errors 54 2
Data Rate 3808 448 kbps
Latency INTERLEAVED INTERLEAVED




I assumed the data rate figures above were okay , so I'm confused my
exchange appears to be only good enough for 1mb.
http://www.samknows.com/broadband/ex...hp?ecode=LCLIT
I've done an autoroute check from my address to the exchange and its
1.7miles away

I've seen a wide range of d/l speeds recently, anything from 25kbs to
300kbs. Is 300kbs consistent with 1mb ????????

After reviewing the link above, can anyone advise whether I'm stuck with
what I've got....or anre their any better options to get a good BB/calls
pacakge sorted ??

Thx

Looks like you're sync'd at just over 3Mbps.

The exchange info is based on data from BT that may not have been updated.
And that 1.7 miles may not be the actual route the cables are taking. Also
line quality will affect your speed - I'm about the same distance from my
exchange, yet I'm syncing at up to 7Mbps (although my BRAS has stabilised at
5500 so I'm getting a stable 5Mbps connection).

300kbs is less than my MaxDSL upload speed :P

I assume you meant 300kB/s (B = bytes, b = bits), in which case that appears
to be just over 2Mbps.

Run some proper speed tests. Try the speed test at http://www.thinkbroadband.com,
and a few others. Don't rely on the exchange data, it's probably wrong. Also
don't assume that the speed test is right, as you might be hitting it during
periods of contention, run a number of tests from various sites at different
times of the day to try and find out your actual speed.

That's clearly nonsense since you're syncing at 3808 k.

Possibly some confusion between IPStream 1000 and IPStream MAX?

Even when I looked at the Tiscali 2mb service the same message came up. That
internet link in my OP suggests ADSL-MAX will be available at the end of
March on my exchange.



Tonight I've just done a test on my connection sync :-

Traditionally when I looked at the sync rate on my router it was always
~2900 ( range around 2700-3100 ). I recently upgraded the firmware on my
PT3812 router/modem and it started showing ~3800 ( maybe just coincidence
though )

I've just done an exercise of bypassing the phone extension cable and
plugging the router straight into the BT main phone socket in the hallway,
then putting a temporary 15m lan cable across the house to the PC. Now its
just given me 4256kbps. I'm considered checking with a few neighbours to se
what they get.

My filter was just a bog standard one that come with the router 3 yrs ago.
Is it possible to get better quality filters or are they all much of a
muchness ??

Further to above I've seen a site which suggests taking off the BT faceplate
off the box and plugging straight into the test socket. I did this and
achieved 4800-5000 kbps over half a dozen router re-boots
Although it wasn't any quicker and the ADSLguide.org speed checker gave a
crappy d/l rate of 950kbps.
Also the attenuation increased from ~37.5 to ~40.5 dBA and the SNR has
dropped from ~6.5 to below 5.

So what does this all indicate ????

What *message* ????

You're being painfully vague.

There is no link that does anything useful in your OP. It just leads to a site.
So ?

Fine. You're not on a 1Mbps or 2Mbps service.

Who *IS* your current ISP ?????? What are they billing you for ?

Much of a muchness IMHO. Others say otherwise but I've 'been through the mill'
with my line until it was straightened out by BT and the microfilters made zero
difference. Removing the extra bell wire on the extension circuit did help
though.

Taking a rough guess by your attenuation and SNR figures I reckon you might be
good for up to 4Mbps.

What does Virgin.Net say? Seems to me they might be limiting your traffic
to 1000 kbps (if that's what you're paying for) though your line is able
to cope with higher speeds than that. If the SNR is below 6db, the odds
are that a lower speed (to give you 6db) will be used some other time
you connect (6db is a sensible level that should allow your connection
to be stable and not disconnecting all the time, but the trade-off is a
slightly lower speed, a reasonable "price" to pay, to stay connected!)

Your upstream sync of 448kbps proves that is wrong - 448kbps upstream is
only on MAX.

When you connect up to MAX your router and the DSLAM will negotiate the
highest sync rate possible, but the SNR will be about 6db. This will
normally start to drop, and you'll get disconnected. When you reconnect, a
lower sync rate will occur, and over time this may degrade till you
disconnect. What happens is that you sync at a lower speed each time, until
the connection remains stable. If you disconnect some time later, and then
reconnect, you may find you sync at a higher speed again, and you start the
training process again until a stable rate is found. A stable connection is
normally where the SNR remains at 6db or higher - once it starts dropping
you'll probably get disconnected to retrain.

It's obvious that there is not a rate limit of 1000kbps on your line as
you've stated you've seen speeds up to 300kB/s, which is over 2Mbps. The
slow downloads from ADSLguide could well be due to contention at the
exchange, or a busy period at ADSL - which is why I said you need to try at
various times (ideally something like 3am where most people should be
sleeping and their PCs are hopefully off, but you may be on the same
exchange as some heavy p2p downloaders so the early hours might not make any
difference).
