Hi stathe,
I've tested your line and it looks like your line profile is set to 6dB SNR margin which is a little low considering the high loop loss.  This low SNR margin is likely causing the drop outs and the variable speeds.  I have initiated an SNR reset which will retrain your line over the next ten days in order to re-stabilise your line.  Please monitor your connection and let us know if the problems continue.  Bear in mind initially you will likely see some drop outs and fluctuations in your speed during the training period.

Will keep an eye on things,but it has all been acceptable until the last week, goes down and reconnects at 800 or so

This is not as good as has been

Has it recently rained a lot in your area?  I find my broadband loses speed after heavy rain.

[#7]

Yes it has ,I am also 3 or 4 miles from the exchange !!! Things have been acceptable all summer but we have had very little rain and only last weeks hard storms and then internet problems

Speed Saturday  now  239 down 380 up
Fri eve                1149          380
Thur                    805            380                      Seems wrong somewhere

[#9]

Very slow again this morning down 237  up 375 down  This with a connection speed of 1248 and Noise margin of 10

[#10]

Hi there,
Looks like it jumped up to 1250 at about 8pm last night, have you noticed an improvement there? Should be working a lot better now, hopefully.

[#11]

Thanks but not aware of that  as now  17-44 pm    Down  263    Up 378
Download speed 1536 with a noise margin of mostly 8 since 07-17 this morning no disconnects as far as I know  Should I reboot the router ?? or best left until to-morrow ?
Regards  Ed

[#12]

Check Current line speed in this Member Centre page. That needs to match your IP Profile.
If that says 1250kbps/1.25Mbps I suggest disconnecting from Plusnet using the router's web interface, then reconnect. There should be no need to reboot the router (which would cause a re-sync and might lead to a lower sync speed).

[#13]

Thanks for that            It says Estimated 1.0 mb
            Current      1.25 mb                      I have in fact rebooted  and now have  conn speed 1920 and  noise 6
Speed now  278 down 380 up Will probably have to just wait

[#14]

Your download speed should be higher than that. Wonder if there's a profile mismatch across BT systems? That's something Plusnet would have to check. Looks like a 'wait until tomorrow' job.

[#15]

No better this morning as here, though I cant say I understand very much , a big disconnection last night and a short power cut, this router soon reconnects, I will wait and see, I think it is a line deterioration
