Xfinity Modem w/Airport Problem SOLVED

I have spent a considerable amount of time trying to make my Airport Time Capsule, Airport Express, and Comcast XB3 Gateway to cooperate. I did it. This is what I learned:

1. The Cisco DPC3939 or XB3 is probably the worst modem/router created. In order to get it in bridge mode, you must do these things in order:
   1. Unplug the XB3 ENTIRELY and put it in the fridge for 5 minutes.
   2. Connect a computer via ethernet to the port labeled “1” on the XB3. (Make sure the computer’s Wifi is turned off so it only tries to get internet through ethernet)
   3. Connect the power, phone, and cable to the XB3.
   4. System Reset the XB3 by holding the reset button for at least a minute and press the phone button on the top at least once.
   5. When it has finally restarted (Which takes about 15 minutes) Type in “10.0.0.1” in your browser.
   6. Sign in with “admin” as user and “password” as the password.
   7. Click on “Connection” then “MoCA”
   8. Click on “Disable” and then “Save”
   9. Then go to “Wifi” and disable both bands (2.4 & 5).
   10. Then go to “Local IP” and uncheck “DHCP” (really just uncheck anything that is there)
   11. Finally go to “At a glance” and enable “Bridge Mode”
   12. It’ll freak out and take 90 seconds to get its wits about itself.
   13. Now it is ACTUALLY in bridge mode.
   14. In order to get an Airport to work with it, set up the airport to create a network, then tap the reset button on the modem just once.
2. Airport Products do have a pecking order.
   1. Time Machines don’t extend networks created by Expresses
   2. Create a network with the most advanced/expensive product, then extend the network with lesser products
   3. If any two Airport products are closer than 15 feet, make sure they aren’t both broadcasting Wifi, makes things not work. Just make one non-wifi.

This has been a ridiculous ordeal. Hope this avoids fear/anger/hate/suffering (Or the path to the dark side).
