Sharp Decline in Upload Speeds
Over the last week, my upload speeds have become slower and slower, making it impossible to have relaible voice and video calls. I'm in SF with a 100/5 tier package. When I run speed tests on Google, Ookla, Xfinity Speed Test, DSL Reports etc, I see download speeds of 75-88, and upload speeds that often average less than 1 Mbps. Two interesting things: (1) the tests show that upload speeds initially spike to 5-8 Mbps and then quickly decline till they get to zero, and (2) this issue disappears over the weekend, when upload speeds are stable in the 5-8 Mbps range. My cable modem was a Sb6141 , which I replaced with an Mb7621 over the weekend, but the issue remains. I am connecting through a Netgear r6400 router, which I've rebooted to factor settings and uploaded all firmware on, without improvement. **I know I need to test levels directly from modem to computer, but am waiting on delivery of the adapter that will let me do this.**. Here is a paste of what I'm seeing on the cable modem. Any ideas on what's causing this? I have a tech visit scheduled for tomorrow, is this likely to help?
