I've been lucky enough to purchase a flat in a FTTC area and have had sky fibre supplied. For about a week after install the speeds (on tests and downloads) were as I would expect - 35+Mb/s.
At some point in the last week or so throughput has slowed noticeably, yet my sync speed has remained unchanged. Since the problem is identical on wired and wireless connections, am I correct in saying this is the result of congestion on the network outside my control?
Broadband Link Downstream Upstream
Connection Speed 39996 kbps 8972 kbps
Line Attenuation 22.5 dB 0.0 dB
Noise Margin 6.1 dB 6.6 dB
(upstream was nearer 10Mb/s when in master socket, but convenience of running on extension socket was worth some upload speed)
