Airport Extreme and Broadband modem setup?

As far as performance, no. But if they are both doing dhcp it can get confusing. Sounds like they are not though.

 

Just curious, what's the benefit of having a "guest" network?

When I had my iPhone set to let me know about wifi networks, I noticed a few places had their normal network and a guest one.

 

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.

Assuming your WiFi network is password protected, you won't have to give a guest your password, either.

 

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.

I use the guest network for visiting friends/family without any issues. Don't be afraid of all the double NAT warnings people mention.

 

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.

If it's worth setting up it's worth doing it right. Some cable modems and gateways have what they call a "modem only" setting instead of "bridge mode." With 2Wires I have had to set them in DMZ mode, and use a different range of IP addresses for the AEBS or Express (10.x.x.x instead of 192.x.x.x for example).

 

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.

 

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.

 

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'.

Any suggestions? I was told that I needed to actually connect to the belkin via LAN to make the change rather than using WiFi but would this really make a difference?

 

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?

 

What about the other details, subnet mask and the others? I'm not very good at this stuff.
