I used to follow this guy 12 years ago.

Years ago I uncapped a 4200 with his methods. It got me 6 months probation from the ISP I was on. Had to go back to dialup yuck.

That was back in the day when the levels of service were 600k/190k and 800k/800k. I paid for 600k service but had it at 800k for months. Then when a storm caused a power outage, you have to reset the modem again. I thought well, I had it at the higher tier for so long and no one noticed. I bumped it up to 2mbps/1mbps (back then that was unheard of!). It worked great until the next morning I woke up to the "Online" light just blinking. A call in, cable co couldn't figure it out. They escalated it and then got a call back saying an SNMP trap indicated values programmed into the modem that they would never do. They said it was hacked and the only way it could of been hacked that way was from the home. They wouldn't believe any story. So the punishment? Had to return the modem and could not sign up for service for 6 months. Lived with dial up for a few months then headed to college anyway.

These days I don't think the config file tells the whole story on your provisioned speed anyway. I think the CMTS handles it now. I'm pretty sure I've seen configs without the speed even defined in it. If the router on the CMTS end has proper QoS in place they can more securely control it there.

These days I grew up, own my own SB6120, and wouldn't even think about uncapping or any kind of hacking. But back in my college days it was pretty fun to tinker with just to see what was possible and get an understanding of how things worked. I'm surprised this guy was still doing this stuff.

I don't know everything they do these days but back then it was 1 64QAM downstream and QPSK upstream. Today its 8 256QAM downstreams and at least 3 16QAM upstreams. They also use a tool called iGlass to look at modem stats. Its a completely new CMTS and a TON of things changed since then.

the lower modulation levels back then allowed a more stable connection to poor/noisy transmission lines.
this is one reason why docsis 1.0/1.1 is still currently used on cable boxes for duplex control.

I remember back in the day when @home was running the show. Even they didn't know what they were doing. You could click on network neighborhood and see everyone on your block connected.

Then again, back then it was. WTF is a firewall.
