similar issues with my line for 3 months. I'm installing T-Mobile 5g home service tomorrow as primary since my router can handle 2 WAN connections, even though I've finally managed to schedule a tech after all this time and all of their outsourced run around that have no idea on Cox policy or US laws. I plan on degrading my Cox service as secondary WAN until they get their act together. or that fibre line that's only a couple of blocks away gets pulled. the funniest part, while I was in the T-Mobile store, I explained why I'm interested in their home connection, apparently the are required to have a hardline cable, but have had nothing but identical issues as mine for months too. it's annoying to see team viewer notifications of all the work computers I monitor, also randomly come back online, both my work and T-Mobile store are only blocks away so it's a widespread issue, yet Cox does nothing.
