High SNR Margin

W00dy · 12 Jul 2007 at 21:32

Just got hold of a D-Link 624 router as a replacement to the Home Hub.

Got a rock solid connection now with no line drops but only connected at 576kbps (IP Profile set at :500)

My SNR Margin is very high - up and down is both 30, with Line Attenuation at 31/47.

Any ideas how I can reduce the SNR Margin which would increase speed?

Or does the ISP have to set the SNR Margin? If so, will they adjust it automatically ( I, for my sins, are with BT

)

Thanks

Yes, ADSL MAX - I should be able to get 3mb at this location. :confused:

Yep upload speed was set at 288kbps, so slower.

I say was because this morning woke up to find no ADSL sync at all :mad:

I have now tried 2 routers, 3 filters and changed the cabling numerous times - do you think I have now elinimated everything bar a line fault?

I suppose it better have a stiff drink before calling the BT Help Desk tonight - I just hope they dont tell me to clear out my cookies again :mad:

Thanks for the info Marmalade.

I am already bypassing any wiring issues as I am plugged directly into the test socket

The SNR Margin did drop during the evening from 30 to 19 at about 11.00pm when I logged off last night. I can only assume the SNR margin dropped too low and hasn't recovered.

Hope BT can sort this thing out it is driving me nuts

OK thanks for the advice will get on to BT - hope the Call Centre staff are a bit more switched on this time.

Thanks Teal mate for taking the trouble to post that link - very interesting.

I have just got off the phone to BT India - I am sorry to say they are next to useless - asked me AGAIN to delete cookies :mad:

god that makes my blood boil.

Anyway no-one had a clue what I was going on about so it is being escalated to the fault team :rolleyes:

also they are switching interleaving off to see if it improves the speed.

I wait with baited breath.

If I wanted to cancel BT could I get out of the contract, as I have only been with them for 6 grief-ridden weeks, and haven't had a decent connection yet :confused:

Just a quick update.

BT have ran tests for the past several days and cannot get Max stable anywhere substantially over 512kbps, so are going to leave me on a fixed IP profile, of 576kbps up and 288kbps down.

Attenuation is OK where I am (47) and my friend 150m away can get 2mbps, so I am at a loss as to the speed difference.

At least the line is now stable and doesn't disconnect.

Thanks again for all your help
