Having an issue with extremely slow internet (.5Mbps). However, when the adsl box is restarted, for a short while the speed is ok (well as ok as available in central London EO area....).
However, it seems that the line test carried out by the adsl provider (nowTV) also resets the adsl box connection speed, meaning that every time Nowtv test the line it comes back as good (15.6Mbps).
So the question is, does a line test reset the adls box connection?
Many thanks

If the line test is causing a resync then it may renegotiate better sync speeds.
Does the ADSL modem not let you see the connection speed, attenuation and noise margin figures.
Drops from 15.6 Mbps sync to 0.5 Mbps sync should be dealt with as a fault. Or are we talking throughput, which might just be an ISP that is running highly congested, or bad wifi issues.

Hi
Thats what I thought.
The sync speed is ALWAYS exactly the same at 15.358Mbps, thats over weeks ecen with new (though same model) router.
Line attenuation varies a little. At moment its 31.5db
Noise Margin 3.6db
about 1.9km from exchage
EO line
single laptop connected with ethernet cable only for testing
connected to test port on openreach master socket with filter

Can you do some speedtests using the TBB tester and post links here? That would allow some analysis of what the speedtests are saying. The fact the sync isn't changing suggests there is some sort of contention issue or potentially a local problem with router or network.

Hi Ian
Thanks for interest.
mostly i use goole sppedtest, but here are three tests using Tbb tester. At momnet speed is good. Thats because I disconnected the phone line physically. good connection lasting a hour so far, but past behaviour suggest about to fail. Just starting to fall over now...

�Disconnected the phone line� how ?
Are you saying there�s a telephone connected, perhaps without a micro filter ?

hi
no phone connected.
only adls box connected to test socket in latest openreach master socket with a filter.
just to rule out other things
ethernet connection only

BQM link is not working - you need to give out the share link rather than the one for the page it is on.
On the speed tests when it went bad the latency had increased significantly from around 50 ms to 199 ms. Have you checked that there is not something trying to do a cloud backup e.g. a phone over wi-fi which with your slow upload will cause lots of problems.

Hi
You are right. After finding that whenever the router is reset or the line tested thats speed would go back to normal and then drop off a cliff, which made me think some issue at exchange, i discovered that disconnecting my main desktop (old mac pro), speed would go back to normal.
So I have discovered where the problem is.
Just for info:
mac in recovery mode now, and speed is normal (at about half expected as busy downloading new system software) So some application running that was really really hoging the bandwidth. Have turned off bonjour (via terminal) and turned off iCloud but neither made any difference when watching the activity monitor. So reinstalling system software to see if that solves the issue.
