Sonoff Fails to go into AP mode or connect to WPA2 PSK AP

[Paulf007]

Describe the bug Sonoff-Tasmota-6.2.1 - fails to connect to Wifi Network and AP mode does not start. I then reverted back to Sonoff-Tasmota-5.12.0 and all worked as expected. Uploaded 6.2.1 to 3 x SonOffs basic with the same results. I also upgraded my AP to a new'ish Edimax and the SonOff Basic refuses to connect to it even it if has a signal strenth of almost 98% It Only diference between the old AP and the new AP is that it is running WPA2 PSK at channel 8 (Saw a previous note on it) vs the old AP WPA PSK is there a fix to this?

Best regards

STATUS 0 OUTPUT HERE

To Reproduce Steps to reproduce the behavior: Uploaded the new firmware to 3 x Sonoff Basic None of my current Sonoff's want to connect to the new AP

(Please, remember to close the issue when the problem has been addressed)

Please fill out the requesting information (in particular the results of status 0, if you don't know how to do that, look at the wiki for instructions on how to do it). Without that we would only be guessing and that is likely to waste everyone's time.

Most people are using WPA2 PSK (aka WPA-Personal), which is the current standard for security in Wi-Fi. WPA3 is not likely to be generally available for some time. https://www.howtogeek.com/339765/what-is-wpa3-and-when-will-i-get-it-on-my-wi-fi/

The esp8266 libraries support WPA2-PSK and so does Tasmota.

However, Sonoff Basic devices seem to sometimes have trouble with Wi-Fi. With Wi-Fi (and RF in general) more signal is not always better.

Hi, seems that you have a problem with your firmware. Try to download again from release or download from http://thehackbox.org/tasmota/

[Josov]

I have the same problem, can't get my Sonoff's connected to the WiFi using WPA2 PSK (tried with 3). Back to release 6.1.1: no trouble, connecting immediately. Downloading a pre-compiled version, flashing it does not do the job either.

[Frogmore42]

@Josov for any help with your problem, you have to provide complete information for anybody to be able to help you. I don't doubt that you are experiencing a problem. Did you follow the troubleshooting steps in the wiki? Did you include the output of status 0? Did you compile the FW yourself? Do you have any non-alphanumeric characters in your SSID or password? There are many things that can cause a device to not connect. Very few of these are under control of Tasmota.

I can conform that this is a problem. For me it always occurs while on 240v, but only sometimes occurs while connected to 3.3v via the pin headers. I cannot show Status 0 at times when the problem is occurring as there is no way to access the console. Status 0 while connected to 3.3v is below.

After powering-up the Sonoff via 240v for a short while, my router log reports multiple connection attempts:

18.09.18 08:59:47 New wireless device registered itself (2,4 GHz), 72 Mbit/s, Snf11, IP 192.168.178.62, MAC 80:7D:3A:18:30:FA.

... and so on...

I can confirm that there are no IP conflicts or anything like that. It works on 3.3v with the same IP address. I can also confirm that there is no password problem - again it works on 3.3v with no changes.

Status 0 while connected to 3.3v is...

This is occurring with three different Sonoff Basic boards. They are all flashed with the same firmware which I have compiled myself with PlatformIO. I have tried restoring one to firmware 6.1.1 and it works fine.

[Frogmore42]

Many people have reported issues with Sonoff Basic devices. Your results indicate that the power supply of the Basic really isn't up to the task of work with the latest code. You are using core 2.3.0. You might try it with core 2.4.2 to see if that makes a difference. You should also try completely erasing the flash and reflashing it, if you have not already done that. If none of that works, you are probably stuck using the older version. I am using old versions on most of my many devices, so that isn't as bad of a solution as it might seem.

[Frogmore42]

I will say, you status 0 log indicates it is not connected to MQTT, so it might not be completely working on 3v3 either.

[Josov]

I completely erased the sonoff using esptool 2.5.0:

I flashed firmware version 6.2 using esptool:

It did not work out well, could not get wifi connected, neither through providing power through the pin header nor using the 240V. However I see the sonoff appearing in the wifi settings on Android phone and on my iPad. But cannot manage to get a connection. It looks like the wifi signal from the sonoff is coming an going. The green led is flashing.

I erased the flash another time and downloaded the sonoff-NL.bin from Release 6.2. The result is the same as with my own compiled version. It is not possible to connect although it looks like the sonoff is broadcasting the SSID. The iPad show the message "Unable to join the network "sonoff-2495""

With release 6.1.1 I do not face problems.

[Frogmore42]

What did the log show on the console (serial since WiFi is not connected)?

[Josov]

[Josov]

I just compiled a new 6.2 version and increased the debug info level to the maximum. First of all the Sonoff did not connect to the wifi network. I checked the ssid and password, both are correct. The password is a simple string of only Alpha's. Here is the result:
