Having trouble SSHing into Raspberry Pi via USB Wifi (ethernet OK)?

Question

I have my Zero on two connections:

Ethernet, via USB cable (with internet sharing from my laptop)
USB wifi dongle, connected to a mobile hotspot

I believe I have successfully configured both connections.

`pi@raspberrypi:~ $ ifconfig

`pi@raspberrypi:~ $ route -n

Kernel IP routing table

I can SSH into my Pi via the ethernet connection, but not the wifi connection.

When I attempt 'ssh pi@192.168.43.253', the system just hangs.

If I ping 192.168.43.253, the ping is successful.

Here is my /etc/network/interfaces file. I suspect something is wrong with it. Perhaps my ethernet is interfering with the wifi scanning. Does anyone know what is wrong?

`auto lo usb0
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
    wpa-ssid AndroidAP
    wpa-psk raspberry
allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug usb0
iface usb0 inet manual`

"Does anyone know what is wrong" Yes you fiddled with the settings.

Put it back the way it came! How do I set up networking/WiFi/Static IP

Exactly what you are trying to achieve is unclear; you seem to have connections to 2 networks. Realistically you need to do one or the other.

Have you setup the wpa_supplicant.conf for Wifi ssid and password? You need to add the following lines to the file:

network={
    ssid="yourSSID"
    psk="yourWifiPassword"
    key_mgmt=WPA-PSK
}

Please disconnect your ethernet connection as others suggested if you want to use your Wifi connection.
