Speed deterioration

I have been enjoying decent speeds for some time but during the gales everything has about halved. No changes to kit or anything else. Has BT /OR been up to something?
Belkin N Router (wired).    Down  Data Rate.    Noise Margin.   Atten .  Up Data Rate   Noise Margin   Atten.
           
                04.01.14                    7616Kbps               8db                 38db         448Kbps          24db              21db
       
     until   05.02.14                     7104Kbps              10db                38db         448Kbps          23db              22db
     until   12.02.14                     6464Kbps               9db                  39db        448Kbps           23db              22db
    until    13.02.14                     7104Kbps               7db                  38db         448Kbps          24db              21db
    until     14.02.14                    3808Kbps              20db                39db          448Kbps          17db              22db
    Now     21.02.14                    Continuing as above.

That's a fairly large jump from previous readings.  Do a few more tests and see if the noise stays the same.  If not run the noise test here http://support.zen.co.uk/kb/Knowledgebase/Performing-a-Quiet-Line-Test and have a listen if there is noise on the line,  Go from there mate.
Good luck.

Re: Speed deterioration

Power down your router at around 10.00am tomorrow morning and then power it up twenty minutes later, check the router stats straight away.
Do a BTw PerformanceTest all the way through i.e. diagnostics etc and check sync and IP profile > http://speedtest.btwholesale.com/

Check the line speed/PN profile in the PN member centre, in other words login to the portal and go here
> https://portal.plus.net/my.html?action=data_transfer_speed to find the current PN line speed.

Re: Speed deterioration

Thanks lads, Powered up today and what did I find?........................
23.02.14   10.53  Download Data Rate  5856Kbs   Noise Margin 2db*  Atten 41db!!!   *never seen it that low before.
Nothing fiddled with here, no evidence of OR bodies down holes or up poles!!  Weather wet and windy as well.  QLT like a grave.
Huh
Done BT Wholesale test:
Download speed 2.92Mps.  Acceptable Range for connection   0.6 to 7.15 Mps. DSL Connection Rate 5.86 **Mps. IP Profile 3 Mps.  ** Belkin always agrees with this.
Looks like a tweek of Profile is needed. I do not like the figures for Acceptable Range, very broad.
