You would only want to use bridge mode if your cable modem was also a router. If it just a plain modem with no built in router you don't want to run bridge mode.
It's a router as well but I am not seeing any conflicts.
Actually, when the AE hangs or stops working, I just switch the AT&T router/modem as I restart the AE.
If the modem is also a router and you do not use bridge mode on the AE or the cable modem router, you will get "double NAT" errors. You may not see them, but they are there and will slow down the responsiveness of your Internet connection. If you were to install the old (more full featured) Airport Utility 5.6 and look in the AE's logs you would see the errors.
It's an isolated network. It will allow "guests" access to the Internet with no ability to snoop around on the separate wireless network that has all of your wireless devices on it.
If you have a friend over and you want to let them use your wifi you can give them the password to the guest network, then change it after they leave. This way you do not have to reconfigure all your wifi client devices (which would not be on the guest network) each time this happens.
I see this over and over again about double NAT.... I've been using my time capsule connected to my fios router, supplying DHCP & NAT for a different subnet than the fios router. Airport utility complained when first setup as expected. I see absolutely NO degradation of wifi or ethernet performance. I've measured it many different times and its always the same as when I was in bridge mode.
Just because your messed up network doesn't seem to be slowing you down doesn't mean the errors are irrelevant to others. It is inefficient. For just lightweight work you may never see anything wrong. But when, and if, you got around to serving information out to the internet, or using home theater type applications, Xboxes or PS3s, etc etc then you'll eventually have things that will not work as expected.
Thanks for your opinion but each setup is different. I have 2 xbox's, 3 iPads, 2 iPhones, and iMac and MBP, a Ruku and Apple TV on my network. I also use a NAS for additional backup and DLNA for movies. My boys are constantly using the xbox gaming online and my daughter loves watching movies from the NAS. I can tell you there are no problems with my setup. The Ruku and AppleTV are running wirelessly and there is no stuttering. Using a DMZ mode will open all ports from the outside world which could be an issue.
That is correct... what you want is modem only mode. You will not need to assign a static address to the AE, it will grab the assigned IP address from the modem when you restart both devices.
Do a search on double NAT and path MTU discovery (which double NAT breaks).
Thank you sir. To avoid further confusion, when I set it the modem/router to bridge mode, that is the same as modem mode? I'm just afraid if I set it up to bridge mode, I may not be able to go back to the modem's config page. I would then have to plug a system via ethernet right?
Yes that is correct. Being a senior engineer in the networking technology I am very aware of how NAT works. Hence the subnet routing/translation which in my situation works perfectly. Thanks.
Yes... bridge mode is the same as modem mode. If you get it all jacked up you would still be able to connect a computer by wired ethernet to the modem to get in and fix it.
Here is a pretty good explanation of double NAT and the potential problems.
My sister is using an AE (Bridged Mode) connected to her Belkin F5D7633-4 (http://en-us-support.belkin.com/app/product/detail/p/417) and I cannot for the life of get it to work when I switch it 'Modem Only'. Everything stops working and I have to revert back to 'PPPoA'.
Hmmm, I can't remember whether I tried that or not (I tried lots of things and neither of them worked) but I don't recall seeing a PPPoE (or PPPoA for that matter) in the AE settings...

If you could perhaps give me some detailed instructions on what I need to do then it would be greatly appreciated.
Thanks. I take it at the top where it says account name and password those would be the same as those the belkin uses to connect with my internet provider?You can see it here in Airport Utility.
What about the other details, subnet mask and the others? I'm not very good at this stuff.
You might check with the ISP but often you can leave those blank and they will fill themselves in once you get hooked up.What about the other details, subnet mask and the others? I'm not very good at this stuff.
