WPA_CLI Use of Debugging Tools

1:run Wpa_supplicant First

Use the following command:

Wpa_supplicant-dwext-iwlan0-c/data/system/wpa_supplicant-c/data/misc/wifi/wpa_supplicant.conf

(use "PS" to make sure Wpa_supplicant is running)

2:run the command line tool WPA_CLI to connect WiFi

Wpa_cli-p/data/system/wpa_supplicant-iwlan0

Then, it'll let you set network interactively

some common command:

>scan = To scan the neighboring AP

>scan_results = Show the scan results

>status = Check out of the current connection information

>terminate = Terminate Wpa_supplicant

>quit = Exit Wpa_cli

>add_network = It would return a network ID to you

>set_network <network id> <variable> <value> = Set Network variables (shows

List of variables when run without arguments), success'll return OK, or would return Fail

>select_network <network id> = Select a network (disable others)

>disable_network <network id> = Disable a network

>enable_network <network id> = enable a network

3:example

For APs that doesn ' t has encryption

>add_network (It would display a network ID for you, assume it returns 0)

>set_network 0 SSID "666"

>set_network 0 Key_mgmt NONE

>enable_network 0

>quit

If normal, we have connectted to the AP "666" and now you need a IP to access Internet, for example:

DHCPCD Wlan0

If everything is OK, it'll get an IP & can access internet

For APS that have WEP

>add_network (assume returns 1)

>set_network 1 SSID "666"

>set_network 1 Key_mgmt NONE

>set_network 1 Wep_key0 "Your AP Passwork" (If usting ASCII, it need double quotation marks, if using hex, then don ' t NE Ed the double quotation marks)

>set_network 1 Wep_tx_keyidx 0

>select_network 1 (optional, remember, if you is connecting with another APS, you should select it to disable the Anot Her)

>enable_network 1

And then, get a IP to access internet

For APS that have WPA-PSK/WPA2-PSK

>add_network (assume returns 2)

>set_network 2 SSID "666"

>set_network 2 PSK "Your pre-shared Key"

>select_network 2 (optional, remember, if you is connecting with another APS, you should select it to disable the Anot Her)

>enable_network 2

There is still some others options to being set, but Wpa_supplicant would choose the default for you, the default would include All we need to set

And then, get a IP to access internet

For Hidden AP (supplemental)

In principle, as long as on the basis of the above set_network NetID Scan_ssid 1 can be tested without encryption hidden AP,WEP/WPA/WPA2 should be the same
