Connecting to WiFi via ADB Shell

Question

I've tried all publicly discussed methods I could find to connect to WiFi via ADB on a phone with a broken screen (no display/no touch). The closest I have got is via wpa_cli using the method #1 described below.

Other methods that I tried are also mentioned but with no success. My goal for this broken phone is to use it as a headless server either via LinuxDeploy or native apps for Android, and for that I need to get VNC running and for that I need to connect to Wifi somehow.

Solutions for connecting to Wifi OR otherwise getting VNC access to the Android display (using ADB usb only) are welcome. I don't have a USB-C Network card so using that isn't an option at this stage.

Method #1 - Using WPA_CLI

In this case I leave /data/misc/wifi/wpa_supplicant.conf and /data/misc/wifi/WifiConfigStore.xml untouched and just pop into wpa_cli using adb shell

wpa_cli Setup

> add_network
0
> set_network 0 scan_ssid 1
OK
> set_network 0 ssid "my_ssid"
OK
> set_network 0 key_mgmt WPA-PSK
OK
> set_network 0 psk "my_wifi_pass"
OK
> enable_network 0
OK

Looks like the wifi interface associates momentarily with the SSID but then immediately disconnects.

The key line here are:

01-01 00:19:36.441  1074  1675 W WifiConfigManager: Looking up network with invalid networkId -1
01-01 00:19:36.442  1074  1675 W WifiStateMachine: Connected to unknown networkId -1, disconnecting...

Looks like the WifiConfigManager won't let me connect to a network which isn't defined in /data/misc/wifi/WifiConfigStore.xml

Method #2 - Naive definition in wpa_supplicant.conf

In this attempt I simply define the entwork in wpa_supplicant.conf and don't touch /data/misc/wifi/WifiConfigStore.xml

Here is what my wpa_supplicant.conf looks like:

wpa_supplicant.conf

update_config=1
ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=wifi
eapol_version=1
ap_scan=1
fast_reauth=1

network={
    ssid="my_ssid"
    psk="my_wifi_pass"
    key_mgmt=WPA-PSK
    priority=241
}

I then proceed to disable and re-enable the wifi service using svc wifi disable and svc wifi enable, and even reboot the phone but in both cases it doesn't seem to even attempt connecting to the network. The invalid networkId -1 message still pops up.

Method #3 - Copying WifiConfigStore.xml from a different phone connecting to this SSID

As a last ditch attempt, I restored the original wpa_supplicant.conf and copied over WifiConfigStore.xml from a phone running the same Android version that successfully connects to the WiFi network in question. Then I rebooted the phone

Still no luck. Don't know what else I can do at this point but not giving up just yet.

scrcpy looks quite interesting. I'll give it a go and report back here. — Fahad Yousuf, Aug 14, 2018 at 3:21
Thank you @Zulakis. scrcpy is working perfect and I couldn't be happier. I've managed to connect to Wifi normally and can resume my experimentation. — Fahad Yousuf, Aug 14, 2018 at 4:18

svc wifi enable|disable should work if it's only about turning WiFi ON and OFF. Or you can use setWifiEnabled method directly by calling service wifi. On Android 8.1 its code (order) is 24, so you can do from adb shell:

~$ service call wifi s16 null i32 1    # Trun WiFi ON
~$ service call wifi s16 null i32 0    # Trun WiFi OFF

But since you also need to add new network to connect, it becomes difficult to go through Android APIs from commandline.

CONNECTING TO WIFI FROM COMMANDLINE:

Another approach is to use wpa_supplicant (and optionally wpa_cli) directly from CLI, don't rely on pre-generated WifiConfigStore.xml or wpa_supplicant.conf.

The following script includes the simple steps:

#!/system/bin/sh

IFACE=wlan0                 # WiFi interface name
SSID=abcxyz                 # WiFi network name
PSK=foobarfoobar            # WiFi network password
DIR=/data/local/tmp/WIFI    # temporary directory
mkdir -p $DIR

if [ "$1" = stop ]
then
    pkill wpa_supplicant
    ip ru del lookup main
    ip r f table main
    ip a f dev $IFACE
    rm -rf $DIR
    ndc resolver setnetdns 0 '' 0.0.0.0
    exit
fi

# set interface up, add rule to lookup into 'main' table
svc wifi disable
for i in /sys/class/net/*; do ip link set down dev $(basename $i); done
ip link set dev lo up
ip link set dev $IFACE up
ip rule add lookup main

# destroy set network  if any
ndc network default set 0

# create configuration file
<<-CONF cat >$DIR/wpa_supplicant.conf
    network={
        ssid="$SSID"
        psk="$PSK"
        scan_ssid=1
    }
CONF

# scan WiFi and connect to access point
wpa_supplicant -B -i $IFACE -c $DIR/wpa_supplicant.conf
until iw dev $IFACE link | grep -q '^Connected to'; do sleep 1; done

# create 'udhcpc' script
<<-'SCRIPT' cat >$DIR/udhcpc_default.script
#!/system/bin/sh

[ "$1" = bound ] || exit 0

# set IP address, add gateway route and set DNS
ip address add $ip/$mask dev $interface
ip route add default via $router dev $interface
ndc resolver setnetdns 0 '' $dns
SCRIPT

# start DHCP client to obtain IP from server
chmod 0755 $DIR/udhcpc_default.script
busybox udhcpc -v -f -q -i $IFACE -s $DIR/udhcpc_default.script

^{* Omit the DHCP part if you want to set IP, route and DNS manually.

* I use my own built wpa_supplicant binary. udhcpc is a busybox applet, ip, iw and ndc are part of stock Android.

* For further options see wpa_supplicant.conf and udhcpc samples.}

DNS:

Apps built with Android SDK depend on Bionic libc resolver for DNS queries, so we need to set DNS servers through native APIs. But still the Java network stack is down, so some apps depending on Android APIs may not behave normally. Programs linked against other C libraries may require resolv.conf to exist. See details in How to configure DNS? and How does Android OS do DNS name resolution?

WIFI DRIVER AND FIRMWARE:

Another problem could be to load WiFi in-kernel driver (as module) and firmware on boot. This is handled by vendor specific wcnss_service which runs in combination with [email protected] HAL. For instance on my device with Qualcomm Atheros Prima WLAN module the service loads firmware (WCNSS_qcom_cfg.ini and related WCNSS_*) files from /vendor/firmware/wlan/prima/ or /persist.

Once you turn on WiFi after boot, all services are started (including wificond) and firmware is loaded. You can check using rfkill or iw phy commands or directly from /sys/class/rfkill. To manually load driver:

~# echo -n sta >/sys/module/wlan/parameters/fwpath

Some more details can be found here, here and here.

When loading driver/firmware WiFi interface should already be created. Check using iw dev or ip link. Or you can manually create:

~# iw $(busybox rfkill -no device list wifi) interface add $IFACE type managed
