HA Voice Preview Edition slow to respond after update to 25.12.4

Configuration Voice Assistant

I have two HA Voice Preview Edition devices. After the update to the 25.12.4 firmware, while both units seem to be handling voice commands normally, one of them now exhibits a significant delay (~10 to 15 sec.) when playing announcements or responding to automations.

For example, I have an automation to turn the HA VPE volume to zero and mute the mic. Before the update it executed with no perceptible delay. Now at least 10 seconds or more pass between triggering the automation and the device actually changing its settings. Even something as simple as turning the LED ring on or off shows a significant delay.

Oddly the other HA VPE does not seem to exhibit any issues, and responds to automations and plays announcements normally.

ETA: While further poking at it, I decided to try pinging it to see if there were any differences with connectivity, and oh boy are there:

Even weirder, if I set up a continuous ping to the problem device, it starts playing announcements and responding to automations much quicker than it had been.

Is it possible the problem unit is going into some sort of sleep mode compared to the other one, and if so, why?

And it looks like this may have been on the wifi side of things instead of the HA VPE side.

For whatever reason after I looked at the settings on my wifi network and reapplied them, it began responding to pings much quicker and is playing announcements and responding to automations normally again.

Static IP vs mDNS? Too much WiFi traffic? Interference? Signal strength? Sunspots (only half kidding - look outside!)

FYI: these are local/non-routable/LAN IP-addresses that don’t leave your private network and cannot be accessed from the outside.
So you don’t have to anonymize these addresses and this is one of the standard ranges for a big part of private networks;

It’s your WAN IP address (the address that your modem/router receives from your ISP) that you should not post anywhere.

Looking over the forums and Reddit, I found a few other cases where Ubiquiti users reported having a similar experience. I think I was originally using the “IoT” WiFi presets (so no WPA3, some of the other features turned off) on my devices SSID but with 5Ghz turned on. I switched it to the “Standard” settings but set the security to WPA2 instead of WPA2/WPA3 mixed mode. No idea why that would change how things worked for one device but not the other.

My best guess is one of the APs needed its config reapplied and changing the global setting forced them all to update.
