Hi
I reported a week or two ago that my boyfriends sync rate had dropped to 2272 after previously being very steady connection of 3.5mb for the last year.
His ISP is BT

I live a few miles away from him and I too have now dropped from a sync speed of approx 5500 to 2272. I have tried using DMT tool to resync my router and even changed the advanced settings to change the noise margin which is a wopping 24.1 but it will not sync any higher (
My ISP is AOL

what on earth can be going on at the exchange, i have checked on the plusnet site and it says the exchange is ok.

any suggestions greatly appreciated

Lisa

It rather looks as though you've both been transferred to a capped 2meg service. Can you copy your router stats here please?

[MrsDaddyCoull]

Hi Eric
thanks for response

here are my stats, adams are very similar sync rate is exact same

we are with different ISP tho, so don't know how we could have both been capped

Yes, it's as I suspected. You've both been capped at 2 Mbps. If your previous, higher speed, connection was reasonably stable, then I think you have a case for complaining bitterly to your ISP about this unnecessary forced reduction in your speed. I would demand to be returned to the regular Max service.

You have been put on a 2mb fixed speed service. No longer on rate adaptive. Typical reason for this would have been severe drop of sync issues inked with poor snr or attenuation of >59db

Your stats look good, line attenuation ok (so your definately not in Oulton Broad near the transport Museum) SNR is good (as your on a fixed speed the higher the snr the better, teens is average, 20's are good) and the errors look clean.

As your a few miles away from your boyfriend I would suspect this is coincidence, best check with your isp why a change in the type of service.

Lowestoft hasn't been my patch for a long time so I'm unaware of any local issues

[MrsDaddyCoull]

Hi folks
thanks for response

can you explain in more detail how you can tell ive been changed to a fixed speed service rather than rate adaptive. its just that i like to get my facts straight before blowing my top at ISP lol

cheers
Lisa

The upstream and downstream line rates exactly match those for a fixed 2 Mbps connection. If you were still on ADSL Max your upstream connection speed would be 448 kbps.

[MrsDaddyCoull]

thanks again Eric

now off to complain to aol, im armed and dangerous with information, they better be ready for me lol

[kitz]

Good luck - let us know how it goes
