Thread: Phone reboots when ejecting wifi

    Phone reboots when ejecting wifi

    Hi All,

    My first post here so be gentle! I've searched the forum but haven't found anything similar yet, apologies if I've missed something...

    I have a OnePlus One running nethunter, using a recommended tplink USB wifi with OTG splitter etc. all working great!!!

    However, when I yank the wifi out, the phone quite often reboots. I see there is a command in the nethunter shell menu to safely eject usb wifi, but this does not work, and generates a warning: "wireless tools not found".

    The main nethunter launch menu has an option to disable external wifi, and this does seem to sort the problem, but I don't know what this is actually doing, and there isn't an option to turn the wifi back on again.

    Any pointers and advice would be much appreciated.

    Cheers.

    OK, running the command (before disconnecting the device):

    rfkill block wlan

    Seems to have the desired effect. And I _think_ that it gets enabled again when starting mana up, and does not interfere with the device in built wifi. I'll test some more and report back how I get on.

    This is a known issue with the wifi firmware (I believe) and people have had success calling the device down before disconnecting.

    Hey binkybear,

    Thanks for the tip. You're right, all that is required is a quick:

    ifconfig wlan1 down

    And then when it's needed again:

    ifconfig wlan1 up

    Cheers!

    "ifconfig wlan1 down" doesn't work on Nexus 7 - 2013

    I've tried PwniePad - no problems with WiFi-Adapter disconnect.

    @schinfo - The problem on exists in Android 4.4.2+ for wlan prima enabled devices. So anything newer then that is going to have reboot issues.

    To get it not reboot on unplugging. Start kali terminal. Do a ip link show up. See if mon0 or wlan1 are up.

    If they are do a ip link set wlan1 down
    And then unplug. This will prevent it from crashing the device.
