I installed the new firmware with ota and also with serial, but i always have the same problem (before i erase the flash).
I've tried them all, even from terminal (the commands "restart" and "reconnect" do not work )

Was it working with previous versions?
Have you checked the password?

Update: with the 1.9.1 version is ok.....with 1.9.2 i don't connect to router wifi.

Between 1.9.1 and 1.9.2 there are few things that could impact the WIFI... the only one I can think of is the WiFi gain... try commenting "WiFi.setOutputPower... " line in wifiConfigure method in wifi.ino module.

There have been some changes in the commands too: "reconnect" is now "reset.wifi", there is also a new "reset.mqtt" and you can still "reset" the board to reboot it.

In case of doubt you can always run "commands" to get a list of available commands.

I also have had problems with the .bin 1.9.2 on my Sonoff RF. Out of multiple attempts I could never get it to connect to my Wifi.

My other Sonoff's (basic and dual) have no issues.

1.9.1 is working without issue.

Same issue here, and with Sonoff Basic. WiFi.setOutputPower(getSetting("wifiGain", WIFI_GAIN).toFloat()); commented, STA mode working good.

Flashed all my devices to Espurna 1.9.2

The only one with a wifi connection problem was the Sonoff RF.
So I can confirm this. Thank you in advanced!

@chistaesse do you mean that after removing that line the device is working fine?

I have a brand new Sonoff basic and can confirm I am getting the same problem.

1. Flashed latest version from GIT as of yesterday, device set up a soft AP and I could connect.
2. Specified ssid and password, reset device multiple times - device never connected to SSID.
3. Commented out the WiFi.setOutputPower line and reflashed - device connected immediately

Fixed with 1.9.4

To be fair the Sonoff POW's that I have work OK with the Wifi gain option. It has enabled me to have a few outside which fixed some coverage problems I have when it was disabled.

Might want to revise if disabling it entirely is a good option.

Thanks
Erwin

+1 for getting Wifi gain option back, it helped me to get stable coverage in some spaces

I think it would be better to add an additional option "Disabled" to the Wifi gain settings, which does not set gain at all. This setting could be the default value to prevent problems with devices not supporting it properly. On devices that support it one could freely choose another setting. Thank you!
