Hello,
I'm able to do a few comcast modem activations, I can provide you preactivated modems that have the HFC mac already activated or you can get your own from amazon (sb 6120) and I'll activate the mac for you.
I'm doing this for $105 one-time fee (BTC). If the mac every changes you can contact me again and I'll reactivate it. The internet will be activated for lifetime after this.
Contact me on XMPP/Jabber:
MilesTyl@exploit.imI can do up to 150 MBP/s down, but it's preferred lower.
