    Final update: my issue has been fully resolved. Cox followed up with me, and it was exactly what I thought it was (RF ingress on the node). This was repaired free of charge.

    So if you're having similar problems, call for a tech and don't be scared off by the talk of a $75 fee. Look at it this way: if it's a Cox problem, you'll get your problem fixed and won't have to keep asking for help on the forums. And if it's a problem in your equipment, you can get it fixed for $75 which is a very low fee for on-site technical services. So either way you get your problem fixed. It's good to post here so you can get advice from others, but once you've ruled out your own equipment, call for a tech and get your problem fixed.

No, it's a straight connection all the way to the demarc. All indoor cables have been replaced. Everything was working perfectly until Monday.

Since there aren't any splitters or amp we may need to schedule a technician out. Please email your full name and address to cox.help@cox.com. Also, include a link to this thread.

    E-mail sent. This morning I was experiencing up to 25% upstream packet loss, but 0% downstream packet loss. Please note this important data point that the packet loss appears to be upstream only.

    No reply to my e-mail yet, but here's more information showing 11% average and 23% peak upstream packet loss but 0% downstream packet loss. This affects any service that depends on upstream data (video conference, audio conference, gaming, etc.) As mentioned before, this seems to have started on Monday.
