Joining WiFi sometimes fails. Be more graceful

[SmittyHalibut]

Sometimes, when joining wifi on boot, it just keeps writing . to the TFT and never succeeds. Be more graceful with wifi connection failures.

• Timeout and retry?
• Timeout and error on the TFT?
• Better error messages. Can we detect if the wifi password is incorrect so a misconfiguration and occasional failure don't look the same?

Option to skip and run off RTC... (maybe people take it somewhere to demo.. who knows)

Maybe this will help?

/* Set the ESP to be a WiFi-client, otherwise by default, it acts as both a client and an access-point

• and can cause network-issues with other WiFi-devices on your WiFi-network. */
  WiFi.mode(WIFI_STA);

This came from a very easy way to handle timezones. It's basically built in.. see here: https://github.com/G6EJD/ESP_Simple_Clock_Functions

I added your suggested code: WiFi.mode(WIFI_STA); It seems a reasonable thing to do anyway.

Mark, I think this is an old issue, never had any problems mentioned above. Probably you can close this as resolved?

[SmittyHalibut]

But! But! But! I opened it! </sarcasm>

Yeah, you're probably right. This was firmware from ages ago, and the WiFi code has changed dramatically since then.

Resolving.

@ExplodingLemur just reported this problem happening to him. Reopening.

Its probably a good idea to put some retry logic around wifi connection failures. That seems reasonable.
