Problems reconnecting to wifi after 20 min timeout. [SOLVED]

Question

I was able to get the unit running fairly easily. Problems with getting the openweather city location, but worked that out. Old Weather Underground was much easier.  Connected without problems the first time out. BUT, when it tries to restart after 20 mins, it says it cannot reconnect to wifi! I disconenected frommy wifi and connected to the 194.168.4.1 and itshowed that my credentials were already in the SPIFF file, and they were correct. The ESPAPER unit shows the connection at around 30% so I moved the unit next to the wifi (78%) and turned it on, it connected the first time, but lost connection after 20 mins. I think the key is that when I turn the unit off, then ON it connects but then might not reconnect after 20 mins.  Ocasionally it does reconnect automatically. Not very often. Second problem is that ocasionally the current temp shows as 0 with the forcast tems being correct.  I love the CASE and the large screen. I also have the wifi color kit and do NOT have problems with wifi, but itdoesn't go to sleep either. I also tried upping to 50 tries and 1000msdelay.. No help

Would be interesting to see what you get on the serial console. Maybe you can try forcefully disconnecting from WiFi at https://github.com/ThingPulse/espaper-weatherstation/blob/master/espaper-weatherstation.ino#L120 by calling `WiFi.disconnect();` and see what difference that makes.

"ocasionally the current temp shows as 0" - make sure you use the latest weather station library 1.6.2: https://github.com/ThingPulse/esp8266-weather-station/releases/tag/v1.6.2. That issue was fixed in that version.

as to the version I'm using... Latest commit 9407952  16 days ago

when I try to use the link you provided I get a 404

"We couldn’t find any repositories matching "

*********************

with my existing code ( NO disconnect added),

note I have added a few more prints and also changed the try loop from 20 to 50 and delay from 500 to 1000ms.

I recompiled the existing code and redownloaded into espaper unit. Connected after 3 tries

 #########  One Successfull reconnect, followed by Several UNSUCCESSFUL attempts.

NOTE:  I made your suggested change

 ( Add your suggested change WiFi.disconnect() after line 120 in main loop.

WORKED.  Ran for 10 updates and they ALL worked as expected. No Failures.

Thanks for your help.
