## Wi-Fi Issues, Arduino Core Versions and Espressif SDK
* For anyone having Wi-Fi problems, please try:
Erase all flash using esptool.py or esptool.exe and flash again by wire (as explained [here](#esptool-usage)) using the latest precompiled bins from http://thehackbox.org/tasmota/.

This approach has solved most of the issues. Sometimes this is due to a bad flashing, a bad OTA or invalid data that remains in the flash where the SDK memory is.

* If you still have issues, you should look into your Wi-Fi network:
Check the Wi-Fi channels availability and noise with an android app like Wi-Fi ANALYZER, and disable Auto Channel in your Wi-Fi router and select any Wi-Fi channel that is not very congested in your area.
Disable Wi-Fi Repeaters and Mesh Networks.
Check Wi-Fi signal in your device.

- Check Wi-Fi signal in your device.
The same Mesh may be stable in one area and lead to unwanted Tasmota reconnects in other areas, presumably when the signals of access points overlap with similar strength. If disabling Mesh Networks is not an option, then keeping the network busy, e.g. by issuing a Ping from another host every 20 seconds has helped to avoid the reconnects.

- If the Wi-Fi router has auto channel, it is not very reliable how it is managed the channel change by this core. Use Fixed Channels in the router instead.

### How To Change Core in Atom & PlatformIO
Locate the platformio.ini file in the project directory of TASMOTA and delete the ; in front of the core you want and add ; to the rest of core options
