I have had my OurWeather kit for over a year.

I have been experiencing some odd behavior relating to it freezing up and such, some of which were resolved with either a code fix or a sensor replacement.

Today, my OurWeather board will no longer connect to any of my APs that I specify.

However, the on-board OurWeather AP appears on boot up.

The wifi configuration setup page appears when I connect to the access point, as expected.

The page properly loads and displays available SSIDs.

I select one, fill out all the information correctly and click SAVE.

The board then says it is connecting, and then returns 255 as the wifi.status code and fails to connect to my AP.

Something fishy with the on-board ESP chip and wifi.

I can connect to it, but it won't connect to any of 3 different APs that I have on 2 different networks.

I will include the serial output.

### FYI, I have a DHT I am using instead of the AM2315/SHT30. There were a few code changes that have been working fine since I added them just after V036 was released. I will include a gitHub link to the code set. ####

!!! This 255 failure no_wifi_shield has come up in the last 24 hours !!!

This is your AP?

SSID:FiOS-EXT1

Is this some kind of an AP extender? I'm just wondering if that is actually the problem and not the WeatherPlus2 board.

I'm asking this because it stretches my spideysense that the ESP32 can still do the 192.168.4.1 AP and not connect to a WiFi.

Let me know.

I have used the Belkin Extender, I have gone direct to my ISP router, I have tried my cell phone hotspot.

Same result.

I can connect to the OurWeather SSID and configure the wifi but it will not save, since the connection attempt fails with 255 (NO_WIFI_SHIELD).

What about an ESP reset? Clear the data in the ESP memory?

Ah, I thought you could make the internal AP work. Sounds like it won't. Back to the dying chip scenario! BP

The internal AP works fine, as far as it appears on reboot, since it fails the wifi connect test, and the config web page pops up automatically, as it should, but it won't take the SSID and Password because it fails the test.
However, it does still have the same, correct SSID and password I entered into it before this issue started, but it will not actually connect to the network.

Sounds like something is wrong with either the WiFi or the EEPROM inside. You could try clearing the EEPROM. Here is the procedure (from the manual):

With the power off connect a jumper from D25 (Presented as Pin 1 on the J15 Grove
Connector) to a Ground wire (Pin 4 of the same connector). On the J15 connector,

Pin 1 is the one inside the board and Pin 4(Ground) is on the outside of the board.
Turn your power on the board and remove the jumper when you see "Trying WIFI AP"
your preferences are completely gone
