1. Files for test:
a. 88W8864.bin: F/W binary. Please put this file under directory '/lib/firmware'.
b. Mamba_FCC_v1.2_5G4TX.ini: power table for Mamba.
c. mwlwifi.ko: 88W8864 mac80211 driver kernel module.
d. hostapd.conf: configuration file used to configure hostapd.
e. openwrt-mvebu-jffs2-128k.img: OpenWRT download image (built with kernel cfg80211/mac80211, iw and hostapd).
2. Bring up driver:
a. iw reg set US
--> set regulatory domain (Note: cfg80211 will disable DFS channels).
b. insmod mwlwifi.ko fw_name=88W8864.bin pwr_tbl=Mamba_FCC_v1.2_5G4TX.ini
--> After module is inserted, physical interfaces phy0 and phy1 and network device wlan0 and wlan1
will be created. You can issue "iw dev" to check them.
c. hostapd -B ./hostapd.conf
--> There are few sample configuration files under this directory. Please use them to do test.
d. brctl addif br-lan wlan1
--> Make sure wlan1 is the interface specified in hostapd.conf.
Note: you can run script file 'setup.sh' instead of issuing these commands one by one.
3. Change configuration:
After hostapd and driver is running, the way to change configuration:
1. Change configuration file hostapd.conf
2. Run "killall hostapd" then "hostapd -B ./hostapd.conf" to run hostapd with new configuration.
4. The way to change channel via hostpad.conf for 80 MHz:
a. You must check regulatory domain first to see if the channel you setting is allowable for 80 MHz.
You can use ��iw reg get�� and ��iw reg set�� to get and set regulatory domain. For script file ��setup.sh��,
it sets the regulatory domain to US.
If you use ��iw reg get�� to check setting regulatory domain:
country US: DFS-UNSET
(2402 - 2472 @ 40), (30, 0)
(5170 - 5250 @ 80), (17, 0)
(5250 - 5330 @ 80), (23, 0)
(5735 - 5835 @ 80), (30, 0)
(57240 - 63720 @ 2160), (40, 0)
It allows you to use three ranges to do 80 MHz operation (36 ~ 48), (52 ~ 64) and (149 ~ 161).
If you use ��iw reg set TW�� to set regulatory domain to TW:
country TW: DFS-UNSET
(2402 - 2472 @ 40), (30, 0)
(5270 - 5330 @ 40), (17, 0)
(5490 - 5590 @ 80), (30, 0)
(5650 - 5710 @ 40), (30, 0)
(5735 - 5835 @ 80), (30, 0)
It allows you set use two ranges to do 80 MHz operation (100 ~ 116) and (149 ~ 161).
b. After regulatory is set and make sure the channel range you want to use is allowable by the
setting regulatory, you can modify hostapd.conf to run 80 Mhz as:
channel=36 -> decide active primary channel.
ht_capab=[LDPC][HT40+][SHORT-GI-20][SHORT-GI-40] -> decide primary 40 MHz.
vht_oper_centr_freq_seg0_idx=42 -> center channel for this 80 MHz.
Test sample:
a. 149 to 161:
channel=149
ht_capab=[LDPC][HT40+][SHORT-GI-20][SHORT-GI-40]
vht_oper_centr_freq_seg0_idx=155
channel=153
ht_capab=[LDPC][HT40-][SHORT-GI-20][SHORT-GI-40]
vht_oper_centr_freq_seg0_idx=155
b. 100 to 112:
Use ��iw reg set TW�� to change regulatory domain to allow to use this range for 80 Mhz.
channel=100
ht_capab=[LDPC][HT40+][SHORT-GI-20][SHORT-GI-40]
vht_oper_centr_freq_seg0_idx=106
channel=104
ht_capab=[LDPC][HT40-][SHORT-GI-20][SHORT-GI-40]
vht_oper_centr_freq_seg0_idx=106
