Dec 11 phone went dead but one leg still connected so got nearly 2Mb download speed.
Phone fixed on 12th Dec; engineer said wire off in cabinet up road (their fault; they had been playing in there, saw them).
Phone and ADSL restored, came back at about 2Mb but ramped up to 4Mb in a couple of days. Couple of weeks later, still stuck on IP profile of 4Mb.
Phoned Virgin Media to see if they could poke DSLAM into action and get back to 6.5MB IP Profile. No joy, said your line capable of between 3.5 and 7.5 and can't report as fault to BT as I'm getting 4Mb.
Tried rebooting router and made things worse; then got (a week ago) 3Mb IP Profile. Appears stuck on that now.Phoned VM again and got nowhere; said contact BT for test.
Phoned BT and got a line test; 99% on voice and they won't even discuss ADSL noise etc.as I'm with VM as an ISP.
Just gone round in circles as nobody wishes to help. Is it a coincidence that my speed halved after line was repaired? I think not!
Have just got 3com router stats from router page; just how bad are they and what speed would you expect? I'm not very good at interpreting them.
I'm only 1 mile from exchange and have been getting 6MB off peak for more than 5 years.
Found a copy of old stats from 2007 for comparison...
Receive att=23dB, Receive margin 10dB, RX output power 0dBm, Send att 11dB, Send margin 26dB.
New readings from 3com below. Can someone interpret them please.
Thanks in advance,
Mike (Retired Radio & Electronics Engineer)
VirginMedia ADSLmax, up to 8Mb.
