50% Drop in Down Stream Sync now Upstream = DownStream :: O2

After 2 years of consistent bandwidth 1.9Mb -2.3Mb downstream 1Mb upstream (admittedly this was probably very good given the Attn, but never the less stable). this has suddenly dropped to 1Mb downstream though upstream is un-effected.

Have tried, Test Socket, Second Router, O2 support etc hopefully all the obvious stuff smile

Appreciate any idea's ... is it even possible to have Down Sync = Up Sync?
