WLED timeouts and missed PONG continuously | Home Assistant | Page 1

I have a single WLED device. It's been connected for more than a year without issues, but in the recent weeks I've started noticing logs like these (pasted in next message).

Device (dig2go) works, and I haven't noticed issues, although it's rarely used so hard to notice.
Device is right next to router, and HA is via Ethernet, also next to it. It can't be a WiFi signal issue.
A WLED update was available recently (I was on 15.1) to 15.3. Tried updating to see if it would resolve, but no difference.
Can't exactly say when it started, but could be HA 2025.12, or maybe 2025.11

I did a quick search for similar issues but maybe I missed some.

Many thanks!

set ip on wled to dhcp and set staic ip for wled in router. Check internal network is up&running, including dns, time (NTP) and you can leave this blank to disable mDNS:

#

reboot afterwards

This is how it was (I just removed the mDNS, but everything else was the same). Router fixed IP was already set.

Wdym with internal network up&running?

#

dns servers setup right, time zone is correct

#

if you can ping google.com from cli, dns will be working

cli from wled? From my computer terminal yes, ping works

#

you can check if wifi sleep is disabled and if there is enough power from amp

#

otherwise, i dont know. Wait here for help or check the wled discord server: https://discord.gg/hnWU43wZ

#

ah wifi sleep is disabled i see.

nothing, no difference. I think this is indeed something on WLED side, not HA. I've set up a ping integration to the device and it's failing a lot regularly for some reason. Not sure if I can debug the connection any other way.

#

have seen errors on disconnect too here.. connection to lights failed. So maybe its wled indeed.

plucky nexus Dec 15, 2025, 7:26 AM

#

but i am wired connected

I think the issue got resolved. My router had a weird issue yesterday where 2.4Ghz network failed. After debugging, it was only when using channel 1 (using it for years without issues 🤷‍♂️ ). So I changed it to channel 6. Now there's no more missed pings.
