Upstream issues getting worse
Having issues with T3 timeouts and packet loss since Monday. It's getting worse. Now seeing multiple T3 timeouts per hour causing average of 3-5% packet loss up to maximum of 10% packet loss. Modem and cable are both almost brand new. Nothing has changed on my end. This appears to be an issue with the Cox network infrastructure. I've had similar problems before and they fixed themselves after a while, but I need a reliable connection ASAP. Please advise of any known issues and ETA for repair.
Downstream signals and error counts are excellent. Upstream power levels are normal (38-40 dBmV). This appears to be an intermittent issue with the upstream connection, possibly due to RF ingress.
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.
