Reconnect to WLAN automatically

Question

Android sometimes has this strange habit of not automatically reconnecting, when it looses connection to the router. I have an Android tablet running 24/7 using a bot to do stuff on the Internet. But sometimes, the connection breaks, and i have to manually click on the wlan symbol in the dropdown thingy the force android to reconnect the the router. This is annoying, because I have to check multple times a day, whether the bot is still working and reconnect if not.

This happens approximatly once/twice a week. I'm using a Samsung Galaxy Tab SM-T230, Android 4.4.2

Does anyone know how to fix the problem/why android does that?

Answer 1

You may be able to fix the problem using Tasker (paid; 7 day free trial) or MacroDroid (free/paid) or AutomateIt Pro and I don't have a reliable way to test my answer so I can't fix some flaws.

MacroDroid

The macro would be:

• Trigger: Wifi State Change → Disconnect from Network → select your network

• Action: Wifi Configure:

  • Connect to Network → select your network

  or

  • Disable Wifi
  • Enable Wifi

• Constraint:

  • Wifi State → Not Connected to Network → select your network

  and

  • Wifi State → Wifi Enabled

Tasker

Profile would be:

• Trigger: State → Net → Wifi Connected → check Invert

• Task: Action(s):

  • Net → Wifi Net:

    • Action: Reconnect
    • check Force

  or

  • Net → WiFi → Off
  • Net → WiFi → On
• Additional trigger: Net → Wifi Near → select SSID of your network

AutomateIt Pro

The free version requires me to connect to internet (which I'm unwilling to) to unlock a feature, so perhaps, free version can also do the job here.

The rule would be:

• Trigger: [Composite AND Trigger]:

  • Wifi Network Connection State Trigger:

    • Monitored Network: select your network
    • Connection State: Disconnected

  • Wifi Network Available Trigger:

    • Network Name: mention the SSID of your network
    • check In Range

• Action: [Composite Action]:

  • Set Wifi State Action → Wi-Fi Disabled
  • Set Wifi State Action → Wi-Fi Enabled

That should work.
