Your on a 0.5mb fixed speed service, figures look good for max/rate adaptive. the only thing is crc errors is creeping up to a figure which may require you to monitor a bit, around 60-70 crc errors (non interleaved) starts to become a concern, once over 110-120 then it's a definate issue

You may be right about the fixed speed service, but the upstream speed of 256 isn't right - it should be 288 for a fixed speed service. That's what's puzzling me a bit.

on the Test my speed is 498kbps and seeing as my Conncetion Rate is 576kbps im guessing my IP Profile would be 500kbps soo my line is nearly maxing my IP Profile  :)

Don't worry. We want to help, but your situation is a bit puzzling (to me at least). With your stats you should be able to get the full 8128 kbps connection speed or pretty close to it. Now you've checked with another router and got the same result I confess to being baffled. Maybe you have been put on a fixed speed service by mistake, and if that's the case then I'm afraid that the call centre is where you'll need to go. But I'm hoping that someone else will turn up with more ideas.

sorry call centre

2 reasons why I said you're on a fixed speed service.

1/4mb upstream not 0.5mb (ish)

30.5 downstream snr. very good snr for a fixed speed, max/rate adaptive you'll never get any where near sync with that figure quoted

Those stats are weird. Like eric says you would normally expect the upstream to be 288.
I was wondering about a traditional fixed speed - but its not - the prescence of FEC errors indicate the line is interleaved so it has to be on MAX.
The atten should be giving the line more than that - and theres plenty of spare SNR Margin.

However, with the large amount of spare SNR - I wouldnt expect to see that many CRC errors, Errored seconds.. and 2 loss of signals.

Now wondering fixed rate MAX by the DLM due to past performance issues? 
Could this line perhaps be seeing noise spikes that the 6 hour period up hasnt shown as yet?  Could it be a large spike (surge) that knocks the connection out before it racks up 100's of errors?

Where is your router plugged in?  Is it on an extension or master socket.
Plugging in your router direct into the test socket behind the master socket is normally the next step.. but if you are on a fixed MAX line then the sync wouldnt change.

If the Btw performance checker was working then it may show up that you are on an assured rate service.  (it gets very busy in the eves).

If you could configure routerstats to work with your router, then it may (or may not) show some interesting results if you let it record the SNR Margin over a longer period of time.

My Router is using the Main Phone Socket as my Extension uses a tottally different phone number but quite a while ago i was recieving 7.1MBPS then it started dropping BT ran Line Check said my line was Perfect but wierdly as my Speed Dropped My Line Attenuation Dropped

>> Dropped My Line Attenuation Dropped

hmmm  that should not happen - attenuation should be more or less a static figure - changes in attenuation are normally indicative of a fault on the phone line.... but even then if the attenuation dropped, this is when you in theory should be getting the better speeds.
An indication perhaps that at one point there was some sort of fault on the line?  Which is when the fixed rate profile could have been applied?

Out of interest can you do a quiet line test? (Dial 17070 and select option 2.)
