I have a question. I have Comcast Internet, a gateway. I want to change my external IP address because I was banned from Ebay (I returned some items and they really don't like that.. lol). Anyway, Comcast said the only way to change the IP address is to upgrade to their business account and purchase 5 static IP addresses. That is very expensive!
My question is: can I purchase a modem and attache it to the gateway to change my IP address? Some Internet forums say, yes this is possible, others say no. I just bought a NETGEAR Nighthawk AC1900 DualBand Router with DOCSIS 30 Cable Modem Black Model: C7000-100NAS. Will this modem help me change my IP address? I have tried VPN and TOR services but Ebay and PayPal ban those almost immediately.
I really need some help regarding this issue. Might you assist me? Thank you for your attention in this matter.
