### I entered the wrong Wi-Fi information
|

Every device with a button can initiate Wi-Fi AP configuration mode with 4 short presses of the button.
|
||||
If you have a device with a button and it is configured as a component in the Tasmota settings, you can try pressing the button to force the device into [Wi-Fi configuration mode](Button-usage) with 4 short presses of the button.
|
||||
|
||||
If you flashed a light bulb or any device without a built-in button and entered wrong Wi-Fi password you now have a device that won't connect to your Wi-Fi and you have no button to force [Wi-Fi Configuration](Button-usage).
|
||||
If you flashed a light bulb or any device without a built-in button and entered wrong Wi-Fi password you now have a device that won't connect to your Wi-Fi and you have no button to force it into Wi-Fi configuration mode.
|
||||
|
||||
To solve this you can try creating a new Wi-Fi AP with the same SSID and no (none) authentication. Use an old router, a mobile phone or, if you're desperate, change the settings on your main router (but remember to turn authentication back on when you're done. Depending on the router/phone it will ignore the wrong Wi-Fi password since authentication is set to none and let your Tasmota flashed device connect to it.

If you are unsure what SSID you have entered, you can try to find that with special Wi-Fi sniffing tools. For example [Nirsoft WifiChannelMonitor](https://www.nirsoft.net/utils/wifi_channel_monitor.html) can show your mistakenly configured SSID name.

If these methods don't work, it may still be possible to save the device without opening it to perform a serial flash:
|
||||
1. Search in your browser history for 192.168.4.1 (or whatever address you used for configuring it)
|
||||
2. There should be an entry similar to this:
|
||||
`http://192.168.4.1/wi?s1=<mySSID>&p1=<myPassword>-********&s2=&p2=********&h=hostName&save=`
|
||||
- `s1` is your first AP SSID
|
||||
- `p1` is the first AP password
|
||||
- `s2` and `p2` are the same parameters but for the second AP
|
||||
- `h` is the hostname given to the device by the Tasmota configuration

Turn off [TasmoAdmin](TasmoAdmin)! It is polling your device with `STATUS 0` command with a HTTP request every 5 seconds which causes the status updates and unneccessary stress load on the device. In some cases it might even interfere with normal device operation.

**In short**: The CFG_HOLDER is the place where the config is stored on your device. The device checks if a config is saved in this CFG_HOLDER (value from the my_user_config.h) and always loads this if exists.
