# The Myndr Switch doesn't do anything when I turn it

If turning the switch doesn't have the desired effect, check the following:

**Is the school's Myndr plan still valid?**
If there is no valid plan, the selected mode will have no effect on the students' internet. You can check this in the [Myndr dashboard](https://admin.myndr.net/cp/switches).

**Have you reset the switch?**
Sometimes it helps to reset the switch. [Here's how to do that](/en/article/how-do-i-reset-the-myndr-switch-1gkpjia/).
Still not working? Then check the following:

**Do the batteries still have enough charge?**
The batteries usually last at least a year. If you have been using the switch for about a year or longer, it will start to beep now and then. This is to indicate that the batteries need replacing. If you want to know exactly how much charge the batteries have left, sign in to the [Myndr control panel](https://www.focusindeklas.nl/beheer).
[Make sure you use the recommended batteries.](/en/article/recommended-batteries-vsus8u/)
Have you replaced the batteries and it still doesn't work? Or is the charge sufficient? Then check the following:

**Is the Myndr plugin installed correctly?**
On a student's laptop, go to the [Myndr status page](http://meta.myndr.net/). It clearly shows which Myndr Switch the laptop is connected to. If the plugin isn't installed, you won't notice the effects of turning the switch either. In that case, install the Myndr plugin and try again. Not the solution either? Then check the following:

**Is the signal from the switch being passed on correctly?**
Go back to the [Myndr control panel](https://www.focusindeklas.nl/beheer). It shows the last known mode.
Turn the switch once and see whether the mode is picked up by the switch in the control panel. If not, wait a moment (20 seconds should be plenty) and reload the page. Does the displayed mode not match the actual mode of your switch? If you haven't done so already, take the batteries out of the switch and put them back in. Wait a minute and try again.
