This mode also allows selection of the channel the wireless adapter uses. The channels available depend on the regulatory domain. If the adapter finds no other ad hoc adapters, this selection specifies which channel with the adapter starts the Ad Hoc network with. The wireless adapter must match the wireless mode of the access point it associates to. n 802.11 Authentication Mode: Select what mode the wireless adapter uses to authenticate to an access point:

Auto: causes the adapter to attempt authentication using shared, but switches it to open authentication if shared fails.

Open: enables an adapter to attempt authentication regardless of its WEP settings. It will only associate with the access point if the WEP keys on both the adapter and the access point match.

Shared: only allows the adapter to associate with access points that have the same WEP key. 4.3.2 Removing a Profile 1. Go to the Profile Management tab. 30
