Mark,

I used to have a LOT of problems with my Cox connection. It was working 
then it would start recycle the modem like every 2 mins for a long 
while. My signal was CRAP!!!!!

Finally, it totally quit all together. Couldn't even connect. Finally, a 
Cox technical person came over. Looked at my cable from the DMZ box on 
the side of the house to inside with a meter and it was VERY bad.

Ended up totally replacing the cable from the DMZ box all the way to the 
cable modem.

Once that was done, my connection came back.

You want to call COX Internet technical support line, don't call the 
help line. Make sure you keep telling them that the connection has been 
dropping like crazy.
