Re: Comcast Service bites! Horrid packet loss, they don't care.

I've been battling with Comcast over horrid packet loss rates from around 5% on a GOOD day to 80% on bad.
Packet loss to where ? Locally, or farther upstream in the backbone ?

 A short test of 5000 pings shows 15% packet loss to my cable modem's gatewaqy IP address as gleaned from it's log file.

Close enough to home?

To my cable modem's IP address (not my public IP, the cable modem's) 0% packet loss on 5000 packets.

Also, it's interesting in that they don't get lost here and there, it will go just fine for a while and then loose a block of them.

Also problems to Comcast's mail server, and any host on the internet I've tried that will respond to a ping... I've been running the smoketests here and they also show high packet loss. The comcast tech (or front line support drone) also did a test while on the phone and saw loss.

Supposedly they are coming back out tomorrow. They were supposed to be here this past Friday, but never showed and when I called dispatch they said the work order was marked complete even though they never showed up and nothing had changed.
