Hi - What setting should I apply when I go to Airport Utilities and open Wireless?
Allow Network to be extended Y/ N ?

Radio Mode 802.11b/g ?

Channel Automatic ?

Wireless Security WPA/WPA 2 Personal ?

Any help would be great. thanks

    Yes only if you have multiple AirPort base stations.

    Radio Mode 802.11b/g ?


    That depends mainly on the equipment you're supporting. If everything supports 802.11g, I'd pick that.

    Channel Automatic ?


    I'd start with automatic. If you have problems with interference try specific channels. In the 2.4 GHz band the best choices are 1, 6, and 11.

    Wireless Security WPA/WPA 2 Personal ?


    If all your equipment supports "WPA2 Personal", I'd use that.

    Is your Time Capsule the latest simultaneous dual-band or the single-band version? Do you need to support mixed 802.11g & 802.11n or only 802.11n wireless clients on your network?

    Its the old single band version and yes I have to support different types of wireless devices.

    Ok, thanks for clarifying. William's responses to your questions are pretty much on the money.

    o The "Allow Network to be extended" option is if you were using another AirPort to extend the wireless range of your Time Capsule (TC).

    o To support mixed wireless clients, the default "802.11n (802.11b/g compatible)" would offer the best performance for these clients.

    o "Automatic" turns out not to always be the best choice. Using a free utility like iStumbler will help you discover if there are competing Wi-Fis nearby. You would want to select a radio channel at least 3-5 channels away from any that you find with a strong signal.

    o WPA2 Personal offers the strongest wireless security but at the price of additional bandwidth overhead. You may find that you will get better performance using the "WPA/WPA2 Personal" setting instead. I would definitely not recommend using WEP regardless of the performance gain as this standard is no longer considered secure.

    This wouldn't work best for you since you want to support multiple protocols, but in my situation I found that I got a big performance increase from setting my TC to run at 802.11n (5ghz).

    I have a Linksys router running 802.11g that is connected to my DSL modem. I connect all of my G devices to the SSID for that access point. I plugged my TC into one of the ports on the Linksys and use the TC exclusively for my MBP. I found that when I connected just my MBP to the TC, with it set in the mixed mode setting recommended above, I only got about 130mb/s. When I run it at the 802.11n(5ghz) I get 250-300mb/s which means my TM backups run faster. Again, this wouldn't work if you wanted to support 802.11G or B devices, but if you only need to support N or have other access points that you can use for your slower protocol devices then you might benefit from this. This is on one of the single radio TCs that are discontinued. I believe the newer TCs actually support running one radio to support N and another to support G, but I don't have any first hand experience with them.
