Open Letter To COMCAST Networks

I've been very patient but, COMCAST is having trouble running their networks. Since I installed my Comcast cable modem in December, about once a week their network drops 5% to 100% of packets between my server and their router.

I contacted COMCAST and was informed that 5% of the packets being dropped isn't very much.

My response is that if you think that losing 5% to 10% of packet loss isn't very much then you should give me a 5% to 10% discount on your network service.

Just to reiterate;

There should be a zero percent packet loss. IP is an error correcting network, 5% is an enormous number of packets to drop and indicates a badly implemented network branch.

Fix it COMCAST. Until you do I want my bill discounted to match the packet dropout rate.

Thank you,

CC. Every other COMCAST customer.

PS. The way you check your internet connection is the following under XP;

create a command window by choosing Start -> Run -> command

In the command window look up your default router with the command ipconfig
and find the default router owned by comcast that is your gateway to the rest
of the internet. Something like 67.DDD.DDD.1 where D is a digit. (NOTE you need to do the ipconfig command on the computer that is directly connected to the internet)

ping the router with the command ping -n50 ROUTER_IP_ADDRESS

Your result should look like this;
$ ping -f -t 67.DDD.DDD.1

Pinging 67.DDD.DDD.1 with 32 bytes of data:

Reply from 67.DDD.DDD.1: bytes=32 time=26ms TTL=64
Reply from 67.DDD.DDD.1: bytes=32 time=7ms TTL=64

Ping statistics for 67.DDD.DDD.1:
Packets: Sent = 10, Received = 10, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 6ms, Maximum = 35ms, Average = 18ms

Mine sometimes shows a 5 to 100% packet loss. ANY packet loss at all is totally unacceptable on a closed network like this.
