Ns Cm 4 Oc Fl a Ar AP -Set preferred access point. -The -.Ar AP -is specified as a MAC address consisting of 6 hexadecimal values -separated by colons. -By default, the -.Fl a -option only sets the first entry in the AP list. -The -.Fl v -modifier can be used to specify exactly which AP list entry is to be -modified. -If the -.Fl v -flag is not used, the first AP list entry will be changed. -.It Fl i Ar iface Fl b Ar beacon_period -Set the ad-hoc mode beacon period. -The -.Ar beacon_period -is specified in milliseconds. -The default is 100ms. -.It Fl i Ar iface Oo Fl v Cm 0 | 1 Oc Fl d Cm 0 Ns -

Ns Cm 3 Oc Fl n Ar SSID -Set the desired SSID (network name). -There are three SSIDs which allows -the NIC to work with access points at several locations without needing -to be reconfigured. -The NIC checks each SSID in sequence when searching -for a match. -The SSID to be changed can be specified with the -.Fl v -modifier option. -If the -.Fl v -flag is not used, the first SSID in the list is set. -.It Fl i Ar iface Fl o Cm 0 | 1 -Set the operating mode of the Aironet interface. -Valid selections are -.Cm 0 -for ad-hoc mode and -.Cm 1 -for infrastructure mode. -The default driver setting is for infrastructure -mode. -.It Fl i Ar iface Fl p Ar tx_power -Set the transmit power level in milliwatts. -Valid power settings -vary depending on the actual NIC and can be viewed by dumping the -device capabilities with the -.Fl I -flag. -Typical values are 1, 5, 20, 50 and 100mW. -Selecting 0 sets -the factory default. -.It Fl i Ar iface Fl c Ar frequency -Set the radio frequency of a given interface. -The -.Ar frequency -should be specified as a channel ID as shown in the table below. -The -list of available frequencies is dependent on radio regulations specified -by regional authorities. -Recognized regulatory authorities include -the FCC (United States), ETSI (Europe), France and Japan. -Frequencies -in the table are specified in MHz. -.Bl -column ".Em Channel ID" ".Em FCC" ".Em ETSI" ".Em France" ".Em Japan" -offset indent -.Em "Channel ID FCC ETSI France Japan" -.It Cm 1 Ta 2412 Ta 2412 Ta -
