Chapter5 Configuring the Client Adapter

Setting Advanced Parameters

Wireless Mode Specifies the frequency and rate at which your client adapter should

transmit packets to or receive packets from access points.

Options:5 GHz 54 Mbps , 2.4 G Hz 54 Mbps, an d 2. 4 GHz 1 1 Mb ps

Default: All options selected

Note When more than one option is selected, the client adapter

attempts to use the wireless modes in this order:

5 GHz 54 Mbps, 2.4 GHz 54 Mbps, 2.4 GHz 11 Mbps.

Note If you choose 2.4 GHz 11 Mbps, the client adapter can associate

to access points containing an 802.11b or 802.11g radio at

802.11b data rates. If you choose 2.4 GHz 54 Mbps, the client

adapter can associate to access points containing an 802.11b

radio at 802.11b data rates or to access points containing an

802.11g radio at 802.11b or 802.11g data rates.

Note When you enable auto profile selection, the client adapter

ignores the selected profile’s wireless mode setting and scans

all wireless modes for an available network. Using this method,

the client does not need to drop the current connect ion nor

change the current profile while looking for networks in other

profiles.

Note Your client adapter’s wireless mode must match that of the

access points with which it is to communicate. Otherwise, your

client adapter may not be able to associate to them.

Wireless Mode When Starting

Ad Hoc Network Specifies the frequency and rate at which your client adapter should

transmit packets to or receive packets from other clients (in ad hoc

mode).

Options:5 GHz 54 Mbps , 2.4 G Hz 11 Mbps, o r 2.4 G Hz 54 Mbps

Default: 5 GHz 54 Mbps

Note The client scans the band(s) specified by the Wireless Mode

parameter before creating a new ad hoc cell based on the band

specified by the Wireless Mode When Starting Ad Hoc

Network parameter.

Note Your client adapter’s wireless mode must match that of the

other clients with which it is to communicate. Otherwise, your

client adapter may not be able to associate to them.

Note The 2.4 GHz 54 Mbps wireless mode may not be functional on

some vendors’ products. In this case, the client adapter uses the

2.4 GHz 11 Mbps wireless mode.
