### Advanced Tab

In the Atheros Client Utility, access the Advanced tab by clicking New or Modify on the Profile Management tab, then clicking the Advanced tab in Profile Management.

Edit the fields in the Advanced tab of Profile Management to configure the profile.

Make sure to also edit the General and Security tabs.

Transmit Power Level | Selects the transmit power level for 80211b/g or 802.11a in mW. Actual transmit power may be limited by regulatory domain or hardware limitations.Also note that administrator has the privilege of locking these power levels, so that these values are pre-selected and not editable.

Power Save Mode

Specify:

- Maximum mode causes the access point to buffer incoming messages for the wireless adapter. The adapter periodically polls the access point to see if any messages are waiting.
- Normal uses maximum when retrieving a large number of packets, then switches back to power save mode after retrieving the packets.
- Off turns power saving off, thus powering up the wireless adapter continuously for a short message response time.

Network Type | Specifies the network as either infrastructure (access point mode) or ad hoc .
802.11b Preamble | Specifies the preamble setting in 802.11b. The default setting is Short & Long (access point mode), which allows both short and long headers in the 802.11b frames. The adapter can only use short radio headers if the access point supports and uses them. Set to Long Only to override allowing short frames.

Wireless Mode

Specifies 5 GHz 54Mbps, 4.9 GHz 54/27/13.5Mbps, 2.4 GHz 54 Mbps, 2.4 GHz 11Mbps, Quality of Service, eXtended Range (XR)TM, or Super AG operation in an access point network.

[eXtended Range(XR): http://www.atheros.com/pt/index.html][Super AG: http://www.atheros.com/pt/index.html]

The wireless adapter must match the wireless mode of the access point it associates to.

Wireless Mode when Starting an Ad Hoc Network

Specifies 5 GHz 54 Mbps, 5 GHz 108 Mbps, or 2.4 GHz 54/11 Mbps to start an ad hoc network if no matching network name is found after scanning all available modes.

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 the which channel with the adapter starts the ad hoc network with.

The wireless adapter must match the wireless mode and channel of the clients it associates to.

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.

Roaming Strength | Select the roaming level to suit the roaming aggressiveness of the client. Five roaming levels ranging from Very Low to Very High allow for the best performance in different environments such as home or office.

For infrastructure (access point) networks, click the Preferred APs button to specify up to four access points to which the client adapter should attempt to associate.
