Well, we are talking about RCN in Chicago. Was going to set this up for a friend of mine, they called and were assured that this could be done without a fee or a tech visit. Unfortunately, the techs on the phone were not cooperative. This was even after the modem they used for the initial setup died a week or two after the installation. So they screw the customer with a defective modem (knowingly I might add, tech admitted that they don't use 3com anymore) and when the customer wants to install their own store bought one they want to charge them $50 for something that is going to take maybe 15 minutes time to setup.
I connected the modem myself (too easy!) and called tech support to report the Mac addr to them to get connected, but they said no way. I mean, what the hell is a tech going to do differently? This isn't rocket science. I would think they would want to send the tech out to do a new install rather than waste their time for $50. So, my friend told them to get lost. They end up losing $40/month over a one time $50 fee. Pretty pathetic! RCN are you listening? Bad business policy.
