Will switching ISP get me a better sync?

On the 25th of this month we are having BT Broadband activated on our line, the btw database estimates a sync of 16-19Mbps.

However, we are currently with Tesco up to 8Mbps seeing a sync of 6848Mbps, this is with an SNRM of 9db and an attenuation reported by the router as 6db. Obviously this shows our line is underperforming.

My question is this: in your opinions will I see an increase in speed with a switch to BT using ADSL2+ over Tesco using ADSL? As far as I and open reach know we have no voice faults on the local loop line.

In other words, is this under performance more likely related to the local loop or something upstream at the exchange?

Thanks

It's also highly likely to be your answer to. ADSL2+ will sync up higher on shorter lines, than ADSL, hence the difference.

Based on the lengthy threads it is hard to say for certain, but a reasonable chance that things will be better.

The description you have provided is not so much will switching ISPs give you a better sync, rather one of will chaning BB products (ADSL2 vs. ADSL1) give you a better synch? Given the estimates from BTw the answer appears to be yes.

The question you should be asking is will BT as an ISP provide you with better customer service than your existing ISP? No matter who is the ISP, unless you are with Virgin or another cable supplier, the last leg of your circuit is always going to be a variable quality BT copper / aluminium pair.

Given all of the problems with changing email addresses etc, you might have been better off asking Tesco to switch you to ADSL2.

Basically, is my existing underperformance likely to carry over to a BT ADSL2+ connection?

My guess would be that the DSLAM our line is connected to will be changed, so if the underperformance is being caused at the exchange or further upstream, then this should sort it

Tesco is supplied by C&W, but C&W are not LLU'd at OP's exchange, so no ADSL2+ available there.

In case you are thinking WBC, C&W non-LLU is like O2 Access or Sky Connect. They only re-buy ADSL Max, not WBC.

@OP: No need for me to repeat my thoughts on the subject; only suck-it-&-see will answer your Q.

It might, depends on the cause of the under performance which without more investigation and trying different hardware which you have failed to do, then no-one is able to say.

No one give you certainty on this things, ADSL2+ and ADSL are very much try it and see services.

If you had decided on a Plusnet no contract deal then you could have given 21CN WBC a try. If after a while things are still not satisfactory then you could switch to partial LLU.

I had problems with the BT exchange kit (IP Stream) in the past which I could never seem to get fixed and it was only a change to partial LLU that cured the BB problem. Hopefully you will not have similar issues with 21CN WBC on your line that I had with 20CN but having the option of partial LLU when not in a contract with a ISP using 21CN can have advantages...

Thank you all for your replies, it does seem to be a case of wait and see, thou I'm pretty sure our local loop is fine, and if I read kitz correctly switching to 21CN WBC will mean I get switched from a DSLAM to an MSAN, assuming my current connection is over 20CN network I'm hoping this will fix any issues related to the DLM as the switch will put the line on the so called 3 day training and re profile it, which to be honest should have been done after the new line was installed at the end of January

According to Kitz will the migration be ipstream <> ipstream or ipstream<> datastream?

Neither nor any other of Kitz's routes. You're getting too involved again.

You are probably on MSAN already (I don't know nor care about flavours of exchange kit as it doesn't affect end-users) as you are already on WBC but delivering an ADSL Max type profile.

EDIT: In all probability, no physical change need to be done to your exchange wiring; it will be done by programming the DLM to switch you from an IP Stream ADSL Max like profile to a WBC ADSL2+ one.
