Someone stole the mac address on my modem :(
The technician checked the signal and said that the signal was fine and that the issue was that my modem had been cloned so the Comcast server automatically banned the mac address. He showed me around 5 other modems from other customers that he had in his truck that he replaced because of the same problem. He asked me if I wanted to rent a modem from Comcast but I refused because I didnt want to pay a $5 rental fee per month + tax.
The modem that I had was a SB6120 which I purchased back in 2009 from Amazon.com (directly from Amazon) so I know that the seller didnt write down the mac address and screwed me over. The only way for the mac address to have been stolen was from Comcast by a technician or through sniffing for macs from their network.
What I wanted to ask by creating this thread is if there is any way for me to protect myself from mac sniffing when I buy a new modem so the same thing doesnt happen agian when I buy another SB6120.
I tried asking Comcast if they could give me some sort of compensation but they said that all they could do was offer me a discount on my bill for the time that I had issues with my service. I tried pushing to get a free month off by saying that a new modem would cost me $60-$80 which is around the same thing that I pay for my bill every month but the billing rep wouldnt budge.
