Ridiculous Packet Loss

Currently getting anywhere between 20-30% packet loss on uploads and upload speeds of < 1 Mbps. I've tried multiple coax cables, checked all the connections, tried multiple devices connected to the network, bypassed the router and connecting my PC directly to the modem, and rebooted the modem multiple times.  If I connect to a local xfinitywifi hotspot, I get the exact same experience, which tells me it's not my hardware. This is preventing me from doing my job effectively.
