Hi! I'm a CableMax 1000 client from Leipzig (04109) and recently, my connection quality degraded below any reasonable point. I have at max 30-50 Mbit downstream and around 0,2 Mbit (!) upstream channel with frequent drop-outs which makes it impossible to use almost anything online. The issue is present on all wifi-connected devices and on my xbox connected to Vodafon Station wia UTP wire.

I've attached my DOCSIS protocol status report, maybe it will be useful.
Best regards,
Dmitrii Systerov
