Please put this file under directory '/lib/firmware'. + b.

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 ˇ§iw reg getˇ¨ and ˇ§iw reg setˇ¨ to get and set regulatory domain. For script file ˇ§setup.shˇ¨, + it sets the regulatory domain to US. + If you use ˇ§iw reg getˇ¨ 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 ˇ§iw reg set TWˇ¨ 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 ˇ§iw reg set TWˇ¨ 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 + |
