Shelly RGBW2 NOT Connecting to WiFi after Firmware Update

    Hello,

    I have a Shelly RGBW2 Color it was working perfectly as AP and as a WiFi client until I made a firmware update to 20210429-101438/v1.10.4-g3f94cd7 (the latest version).

    Now it's work as AP only and NOT Connecting to the Wifi network (the same one before the update).

    I already tried the Factory rest (both way the Hard reset and Soft reset) but I couldn't wipe the new Firmware.

    I also searched for a way to downgrade the firmware but I couldn't find where I can choose a firmware to downgrade to it.

    Thanks in advance

    Be aware that the Beta (1.10.15) has a problem with hidden WiFis. With hidden WiFis the beta version the Shellies just disappear into neverland (they don't connect to that WiFi but also do not go into AP mode). Making the SSID visiable solves the issue temporarily

    My Shellies: 15x 2,5 / 3xRGB / 2x 1 / 2xEM / 3x4Pro / 4x3EM / 4xi3 / 20x Duo RGBW E27, 10x Duo RGBW G10

    Hi,

    I am not sure if I should open a new thread since this one is marked as resolved.

    But I am having exactly the same issue.

    I have 4 shellyrgbw2 devices.

    The only one that is still working is on firmware 20210909-145300/v1.11.4-DNSfix-ge6b2f6d

    The three that are not working are running

    20210429-101525/v1.10.4-g3f94cd7

    They were all working fine for some weeks (they were installed about a month ago).

    The symptoms are:

    * Works fine in AP mode

    * Does not work in wifi client mode

    * From the Unifi Controller I can see the devices are connected, but without an IP address.

    Measures taken:

    * Restarted all network gear

    * Ensured DHCP Server has free ips in its pool.

    * To rule out DHCP issues I configured one device to connect with a static IP. In this case the device connects to my AP but does not respond to pings or http requests.

    * Ensured wifi SSID network is configured according to the many instructions here on the forum (pretty much all settings disabled)

    Should I try an ota upgrade by running an http server on my laptop while connected in AP mode?

    Any other possible measures to take?
