Thanks for confirming it is working for you! That was immensely helpful. I captured some wireshark traffic on my wifi network and have figured out the issue. My DHCP server has the lease time set to one hour and that was causing a significant amount of broadcast traffic that was causing issues with the ESP8266 devices. I increased the DHCP timeout to 1 day and the devices are now very stable. I also confirmed more stable behavior by using static IP on the devices as well. Issue seems to be resolved. I have some occasional crashes but I will work on that separately.

I see this issue as well. Or a similar at least, where some devices on the network actually have uninterrupted healthy access to WLED but others don’t. Same test, i flashed another ESP8266 with another application (ESPHome) and i dont see this issue (inconsisstent ping, or access to webGUI).
I ended up creating another SSID in my AP + a VLAN with a different IP address range on DHCP and i see no issue now at all. So the WLEDs connect to the other SSID and use a different IP address range on my network. Yes i am on a UniFi network
There is an open discussion here about that issue:
I’m not experiencing this issue myself, but something that I quite like about the Tasmota firmware is the ability to add 2 different SSID’s, and there is a setting where you can tell the firmware to auto connect to the strongest WAP in range once an hour.
Is WLED had the option for a 2nd/backup SSID input then may be handy for people running multiple Wifi access points.
Hello to all, i got the same issue !!! BUT i found a VERY strange solution - for me ! i dont know if it works for you as well. i have a ESP8266 board for the WLED.
i just found out that the wlan connection is very unstable. device not reachable and so on … ping -t shows conection losses high pings and low pings …
for testing issue the device was powered via the mini USB Port … and thats the point … it seems that something is wrong with the USB Port !!! if its just plugged in the connection is very bad.
i bend the pluggeg in Plug with my finger a bit upwards and hold it like this … and there the miracle happens … ping goes very good and no connection losses and the device is always reachable !!!
maybe a bad conenction or a mini short that causes wlan to collapse ?! and then i switched over to the VIN and Ground pin to power the device and there is absolutely no issue anymore with bad signals !!! so powering via Pin VIN and G works well … USB is messed up !!! can anymody confirm this strange issue ???
That’d be on par for a bad USB cable or damaged port yes.
i dont now cable is crosschecked and everything …
can somebody help me with a new bin file for the ESP8266 and raise the GPIO Buttons from 2 to 10 ?
i dont know how to make one 
You could use this: https://wled-compile.github.io/ to create a script and then compile with github or vsc/platformIO. They give you all the details.
thanks for the hint i manage to getit to work with it ! 
awesome !
