I just went out and bought the new AirPort Extreme. I set it up with AirPort Utility, and it broadcasts my network but in AirPort Utility it shows there's no internet.
Now, the thing I don't understand is when it's plugged in via the modem it doesn't show the internet. But, if I plug in Comcast modem into my old Netgear G Modem, and then plug my AirPort Extreme into that, it shows there's internet in AirPort Utility.
How can I get it so where I can disconnect my G Modem completely and run my Comcast modem to the AirPort Extreme?
Comcast wanted $49.95 to diagnose and fix the issue, I told them "######" and they hung up on me.

Docsis 3 allows for channel bonding, this can handle congestion better. And also allow for much higher top end speed, but the big thing is the use of multiple channels that are bounded together
I believe you can look on your modem at 192.168.100.1 as well for your signal info, notice the 4 channels here in downstream and 3 used for up.
If you have 8 channels vs 4, its highly unlikely that all 8 out of those get maxed out, etc. And your more likely to be able to get your rated speeds without any issues even in prime time, etc.
Not that you can not easy get your speed with 4, its just 8 gives you less likely hood of running into say primetime issues where you only say 30mbps vs your rated 50 is all.
It may or many not be an issue for you.. But It think it is like a $10 for the 8x4 one vs the sb6121 that is only 4x4. Go to the full post
