Re: BT Chat Advisor

your download speed is set by your IP Profile which is 96.79% of your actual connection speed you actual download speed can be anything up to your IP profile

also a speedtest carried out wirelessly is not accurate

Re: BT Chat Advisor

I've had to complete wired speedtests as the bt customer advisors won't progress with troubleshooting unless your using a wired connection.

Whilst "vectoring" does appear to potentially solve some of the issue of crosstalk how long will this take to roll out? And in the meantime I'm not receiving speeds quoted with the potential for further degredation

If crosstalk is a relevant factor to degredation of service and I was encouraged to sign up based on receiving maximum speeds do you think it worthwhile I attempt to "renegotiate" my costs?

Re: BT Chat Advisor

At 70mb you are still getting a better connection on infinity 2 than many and as it is within your estimate then I would think it highly unlikely BT will negotiate anything. As your noise margin is above the norm of 6db it may still reduce giving a speed increase provided you can maintain a stable connection. It may take 3 weeks maybe longer

Re: BT Chat Advisor

Based on the DSL checker on the A range of a clean line the low downstream I should expect is 69.4mbps and router stats are currently showing 68.45 mbps so I'm currently just outside the lowest range!

If the crosstalk is affecting the SNR how unlikely is it to return to 6?

Re: BT Chat Advisor

Provided quiet line test is ok then I still think you will get a bit more speed when noise margin drops to 6db

Those figures on the BT Wholesale database are sync rates rather than throughput speed, as overheads, IP profiles configurations can be slightly different between ISPs.

 

As your sync rate is at 70Mbps then you are still just within the A range.

 

If it degrades a lot more, and the DLM doesn't slightly increase speed (which can take upto 3 weeks+), then it can investigated.

 

As imjolly has also said, make sure your line is okay quality wise (ie no audible noise on the line) via the quiet line test.

Re: BT Chat Advisor

Sorry I was looking at the stats in the "connection" rather than the "help desk"

Re: BT Chat Advisor

I'll keep an eye on the stats and keep my fingers crossed for the dlm.

I have called the quiet line test and all seems to be quiet during the call (although I do get some clicks initially)
