This feature is only available on certain products and models (not available with all devices).<\/strong><\/p>\n

Configuration of RS9113 driver on the Device<\/span><\/strong><\/span><\/p>\n

If you are using the rs9113 as a Wi-Fi Station, \/etc\/default\/rs9113<\/strong>, on the device, you must have the COEX_MODE <\/strong>variable set to 1<\/strong>, 3<\/strong>, 5<\/strong>, or 9<\/strong>. Also, you can set the country code and other parameters as documented in \/etc\/default\/rs9113<\/strong>.<\/p>\n

1. If hostapd produces errors, the COEX_MODE is incorrect. To prevent the driver from loading during boot set the value of RS9113_LOAD<\/strong> in \/etc\/default\/rs9113<\/strong> to zero:
\n<\/span><\/span><\/p>\n

RS9113_LOAD=0<\/pre>\n
2. Reboot.<\/p>\n
3. Correct the COEX_MODE<\/strong> value.<\/p>\n
4. Change the RS9113_LOAD<\/strong> value back to one in the file, \/etc\/default\/rs9113<\/strong>.<\/p>\n
5. From the shell, now reboot again and load the driver by entering the following command:<\/p>\n
mtcdt: \/etc\/init.d\/rs9113 restart<\/pre>\n
NOTE<\/b>: Whenever you change the band of the rs9113 module you must reload the driver. The rs9113 module only supports 5GHz or 2.4GHz, but not both at the same time.<\/p>\n
Bring up the VAP (Virtual Access Point) Node for Wi-Fi<\/b><\/span><\/p>\n
1. Create network entry for wifi0 and add to \/etc\/network\/interfaces using these lines of the auto stanza (enter them into the file rather than the command line):<\/p>\n
auto wifi0
\niface wifi0 inet dhcp
\nwpa-conf \/etc\/wpa_supplicant.conf
\nwpa-driver nl80211
\npre-up bash -c ‘([[ -d \/sys\/class\/net\/wifi0 ]] || \/opt\/rs9113\/onebox_util rpine0 create_vap wifi0 sta sw_bmiss)’
\nudhcpc_opts -t 10 -b<\/p>\n
2. Save the file, \/etc\/network\/interfaces.<\/p>\n
3. To bring up the interface for scanning, enter these commands (at the bash line):
\n<\/span><\/p>\n
mtcdt: \/opt\/rs9113\/onebox_util rpine0 create_vap wifi0 sta sw_bmiss\r\nmtcdt: <\/code>ip link set dev wifi0 up<\/pre>\n
4. Then scan by entering this command (signal strengths are displayed in -dBm):\u00a0<\/span><\/p>\n
mtcdt: iw dev wifi0 scan | tee \/tmp\/scan.txt<\/pre>\n
 <\/p>\n
Configuring Wi-Fi Station\/wpa_supplicant<\/b><\/span><\/p>\n
1. You need to create a Wi-Fi configuration. You may already have the necessary information such as the passphrase (psk). But if you do not have this information, the scan command can provide it:<\/p>\n
mtcdt: iw dev wifi0 scan | tee \/tmp\/scan.txt<\/pre>\n

Start the wpa_supplicant Daemon<\/b><\/span><\/p>\n
1. Start wpa_supplicant<\/strong> and bring up the interface (choose the appropriate file) using the following commands:\u00a0<\/span><\/p>\n
mtcdt: ifdown wifi0 \r\nSuccessfully initialized wpa_supplicant\r\nmtcdt: ifup wifi0\r\ndhcpc (v1.22.1) started\r\nSending discover...\r\nSending select for 192.168.1.5...\r\nLease of 192.168.1.5 obtained, lease time 86400\r\netc\/udhcpc.d\/50default: Adding DNS 192.168.1.1<\/pre>\n
2. Now verify the connection either from another screen, or use <ctrl>+z<\/b> followed by bg\u00a0%1<\/b> to put wpa_supplicant<\/b> in the background:\u00a0<\/span><\/p>\n
mtcdt: iw dev wifi0\u00a0 link\r\nConnected to 9c:4e:20:c8:ee:9e (on wifi0)\r\nSSID: Mtech_guest\r\nfreq: 5785<\/pre>\n
3. Enter the ifup from another screen (using ethernet or ssh):\u00a0<\/span><\/p>\n
mtcdt: ifdown wifi0\r\nmtcdt: ifup wifi0\r\ndhcpc (v1.22.1) started\r\nSending discover...\r\nSending select for 192.168.1.5...\r\nLease of 192.168.1.5 obtained, lease time 86400\r\n\/etc\/udhcpc.d\/50default: Adding DNS 192.168.1.1<\/pre>\n
4. Start DHCP if the previous setup did not acquire an address:\u00a0<\/span><\/p>\n
mtcdt: udhcpc -R -n -p \/var\/run\/udhcpc.wifi0.pid -i wifi0<\/pre>\n
udhcpc (v1.22.1) started\r\nSending discover...\r\nSending select for 192.168.1.7...\r\nLease of 192.168.1.7 obtained, lease time 86400\r\n\/etc\/udhcpc.d\/50default: Adding DNS 192.168.1.1<\/pre>\n
Integration of boot, ifup, and ifdown with Wi-Fi station<\/span><\/h3>\n
To allow ifup<\/strong> and ifdown<\/strong> commands to work with wpa_supplicant<\/strong>, and to connect at boot, the file \/etc\/network\/interfaces<\/strong> must be configured.<\/p>\n
This configuration creates the wifi0 VAP<\/strong> at boot:<\/p>\n
auto wifi0\r\niface wifi0 inet dhcp\r\nwpa-conf \/etc\/wpa_supplicant.conf\r\nwpa-driver nl80211\r\npre-up bash -c '([[ -d \/sys\/class\/net\/wifi0 ]] || \/opt\/rs9113\/onebox_util rpine0 create_vap wifi0 sta sw_bmiss)'\r\nudhcpc_opts -t 10 -b<\/pre>\n
The wifi0 VAP<\/strong>\u00a0 does not exist before the pre-up<\/i><\/strong> section is run. The wpa_supplicant.conf<\/strong> file should contain an SSID, and other configurations as shown in the prior section Configuring Wi-Fi Station\/wpa_supplicant.<\/strong><\/p>\n
The udhcpc<\/strong> program has the following options applied at boot and by ifup<\/strong>:<\/p>\n
udhcpc -R -n -p \/var\/run\/udhcpc.wifi0.pid -i wifi0<\/pre>\n
These options specified by udhcpc_opts<\/strong> are added to the end:<\/p>\n
udhcpc -R -n -p \/var\/run\/udhcpc.wifi0.pid -i wifi0 -t 10 -b<\/pre>\n
This means that the boot or ifup<\/strong> command is held up for up to ten attempts to reach the DHCP server.\u00a0The -b<\/i> option<\/strong> means that udhcpc<\/strong>\u00a0is placed in the background after the 10 attempts are complete.\u00a0 Then the boot proceeds or if -b<\/i> option is not specified, ifup<\/strong> command terminates.<\/p>\n
The interface is available after the udhcpc<\/i><\/strong> daemon<\/strong> receives a response from the DHCP server.\u00a0Without the -b <\/i>option,<\/strong> udhcpc<\/strong> holds up the boot or ifup<\/strong> command until the DHCP server responds.<\/p>\n
When -t<\/strong> is set to 0, the -b<\/i> option<\/strong> is ignored.\u00a0 In this case, udhcp<\/strong>\u00a0blocks until the DHCP has responded, and tries indefinitely.<\/p>\n
Without any options, udhcpc<\/strong>\u00a0 <\/i>will wait approximately nine seconds for a response, and abort if none is received.\u00a0 At this point, you will need to try running ifup<\/strong> again, or reboot the device.<\/p>\n
