    331. How to set 802.11 interfaces used on ORBIT
     4
    452. Which settings actually work
    56
    67Available settings: mode (abg), essid, channel, mode (sta, ap, ), txpower, phy rate
    78
    8 Atheros:
     9= Atheros =
    910
    10 Madwifi-old:
     11== Madwifi-old ==
    1112
    12 Madwifi-ng:
     13== Madwifi-ng ==
    1314
    14 ath5k:
     15== ath5k ==
    1516
    16 Intel:
     17= Intel =
    1718
    18 ipw2200
     19== ipw2200 ==
    1920
     21=== Mode ===
     22
     23{{{
     24iwpriv eth2 set_mode <x>
     25}}}
     26
     27where x stands for:
     28
     291: a
     30
     312: b
     32
     333: ab
     34
     354: g
     36
     375: ag
     38
     396: bg
     40
     417: abg
     42
     43=== Interface mode ===
     44
     45{{{
     46iwconfig eth2 mode <mode>
     47}}}
     48
     49where <mode> can be ''ad-hoc'', ''managed'', or ''monitor''. Access point mode (master) is  not allowed.
     50
     51=== Channel ===
     52
     53{{{
     54iwconfig eth2 channel <channel>
     55}}}
     56
     57where the ''channel'' is given in channel nomenclature number (36) or in MHz (5180M).
     58
     59=== Transmit power ===
     60
     61{{{
     62iwconfig eth2 txpower <power in dBm>
     63}}}
     64
     65Alowed range is -12dBm to 20dBm. Actual settings are from -8dBm to 14dBm. Thus
     66{{{
     67iwconfig eth2 txpower 18
     68}}}
     69results in power being set to 14dBm.
     70
     71=== PHY rate ===
     72
     73{{{
     74iwconfig eth2 rate <x>M
     75}}}
     76
     77where the actual range of rates depends on selected 802.11 mode. In other words
     78
     79{{{
     80iwconfig eth2 rate 54M
     81}}}
     82will not work if selected mode is 2.
     83
     84=== Note ===
     85Vector Signal Analyzer shows interesting discrepancy. In ''only b'' mode (2) 6Mbps OFDM is used instead of 5.5Mbps DSSS, and in ''only g'' mode 11Mbps DSSS is used instead of 12Mbps OFDM.
