Cons: I don't know
I had been using the same modem for 12 years. Had become accustomed to the frequently dropped signals, etc and slow download/upload. I dreaded installing a new modem myself and even asked Cox to come to do it. The service rep encouraged me to do it myself as I would purchase a better modem than what Cox would install. I bought a new one and waited a week to install it because I dreaded doing it. Boy do I feel silly. This was really not much different than plugging in any new appliance. Took less than 5 minutes. Works great. No lost signals. Quick downloads/uploads. I'm an old lady (sorta). If I can do it you can do it.
