Hi there,

I'm on TW's broadband 'complete' package (i think it's the medium speed package) and have been quite happy with my downstream speeds of 1700Kbps on a bad day up to about 2500 on a good one.

Last night (tues 17th) there was a sudden drop in my speed, and it has remained consistently low since then. Now my speed (going by the same speed test which gave the prev figures) is averaging 350Kbps, but sometimes rising to 500kbps if i'm really lucky. Also, the orange 'activity' light on my sb5100 modem is blinking slightly intermittently, instead of blinking steadily as before.

In the modem's log for the time when it dropped last night (around half nine or so):

and if it matters:
Downstream:
Frequency 331000000 Hz Locked
Signal to Noise Ratio 38 dB
Power Level -2 dB

Upstream:
Channel ID 3
Frequency 29008000 Hz Ranged
Power Level 41 dBmV

Does anyone know if this means anything, or know what my problem is? I'm currently girding my loins for the inevitable call to customer services which will probably go nowhere, and would like to have some idea of what's what when i call them so they can't just fob me off.
I've unplugged, re-plugged, reset, checked connections etc...
Really hope someone can help

Thanks
