Re: Upstream channels in freefall
As of 22:43 this evening the upstream channels have gone haywire again, modulation is negotiating at 16QAM and massive packet loss is occurring. The service issues consistently begin around 22:30 every evening and seem to last varying amounts of time. 3.0 Upstream channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 0 49600000 46 5120 QAM 16 7 1 43100000 45.8 5120 QAM 16 8 2 36600000 45.3 5120 QAM 16 9 3 30100000 45 5120 QAM 16 10 4 23600000 44.5 5120 QAM 16 11Re: Upstream channels in freefall

As of 10pm last night (and for a brief stint between 10pm and 1am the previous night) my upstream channels 2, 3 and 4 have crippled my connection with large amounts of T3 timeouts and lower than expected modulation (16-32 QAM vs expected 64). My downstream is fine achieving gig1 speeds as expected but my upload speed is down to half a megabit vs expected ~100mbps. Below is my BQM chart for today.Composing, forwarding, replying etc. not working for months on desktop
As the title says, I'm unable to use my email properly on desktop, though emails can still be viewed and received. This has been the case for months so I've mainly been using other devices, hoping the issue would be resolved on its own. As this hasn't happened and its becoming a nuisance I'm hoping someone here can help.
