CM8200 Cable Modem "Upgrade"
I am now on day 10, and second Cox cable modem CM8200 -- and it still does not work!
For years I had a Motorola that gave me consistent 30Mbps (download, 5Mbps upload). Cox upgraded my modem to this CM8200 a couple of weeks ago and right after power up I would get 70-100Mbps download and 10Mbps upload). However after 5 minutes or so my download speed slows to less than 1Mbps!! Upload speeds remain the same.
A Cox technician came out and could find anything wrong so he loaned me a Panasonic modem/router which worked great, and told me to replace the CM8200 (and return the rental unit) which I did. The second CM8200 is doing the exact same thing and now I am waiting for a second visit from a Cox technician and living with a .19Mbps connection!
The receive activity light on the modem is BLUE which indicates it's trying to use DOCSYS3.1 while the send light is GREEN which indicates it's using DOCSYS3.0. I think something in the network is not supporting DOCSYS3.1.
Anyone else experience this and/or have any thoughts on what to do while I wait for Cox's second visit?
