~ Cisco AIR-AG1242AP access point: ~ 1) what's the difference between Workgroup Bridge and Universal Workgroup Bridge?
Standard "Aironet" Workgroup Bridge mode is a purely Cisco proprietary extension to 802.11 and only interoperates with Cisco APs. It permits for a WGB to have a large number of wired clients behind it.
Universal WGB is essentially a "MAC cloning" scheme, where the WGB will present its wired client's MAC as the radio MAC to the AP to which it associates. It only supports a single wired client, and (hopefully) should work with non-Cisco APs.
~ 2) is Universal Workgroup Bridge the same thing as the 'Wireless Distribution System' ~ (WDS)?
Nope, they have nothing to do with each other.
WDS is a scheme on the infrastructure side whereby an AP can act as a common authenticator (in the 802.1X sense) / key manager for a set of up to 60 infrastructure APs. The use of WDS in the infrastructure should be transparent to clients.
~ 3) trying to configure the above 1242AP as a wireless bridge to connect to an O2wireless ~ box router - the O2 help files refer to a 'Wireless Distribution System' being allowed to ~ connect but nothing about a wireless bridge. I need to clarify what a wireless ~ distribution system really is and whether it's compatible with WGB and U-WGB ~ Thanks for any pointers.
I suggest that you state with considerable detail exactly what you are trying to accomplish. Stuff like:
- what infrastructure you have (what make / model / software version of APs)
- what encryption/authentication/key management scheme you are or want to be using
- what kind of wired clients you intend to support behind your WGB etc.
Hth,
