Boom not connecting sometimes

[Tintifax]

I have a Classic and a Boom connected wireless to LMS 8.0.0 on a Raspberry Pi (signal is good, 80-90%).
Everything works well, BUT:
Sometimes, lets say every 1-2 months, the Boom doesn't connect anymore.
It says "connecting" forever.
Turning off and on, recycling power, nothing helps.
After some days plugged off, it will always connect again when powered up as if nothing had happened.
How can I find out what is going wrong?
How can I even find out if it's the wireless connection to the access point or the connection to LMS that is failing?
Log-files on the access point/DHCP server/Boom/LMS?
Thanks for your help!

After a power outage I can only get Boom to reconnect by re-launching LMS and unplug Boom for about 5 mins. Once I plug it back in it does connect as expected.

Oh no, it happened again!

@toby10: Thanks for your input, I checked for any power outage, but uptimes of other network devices proof that there was none.

I found out that the wireless connection fails:
Logfile on my Unifi Access Point says "auth failure".
I checked SSID and password in the network settings on the boom, but they are correct.
So, what's going on here?

Yeah, I wasn't suggesting you had an actual power outage, just explaining my Boom reconnect issues. Or that maybe your router or Boom may have rebooted, creating similar symptoms to an outage. Dunno, just throwing out ideas. Perhaps even a failing WiFi board in Boom.

Could be your routers IP lease renew is confusing the Boom as it is looking for a specific IP for LMS which is now different. Next time you see "connecting" on Boom, press & hold the BACK button to enter Setup menus. Scroll through these menu items twice, sometimes you will then see two instances of LMS, one is the LMS the Boom remembers, second is the "new" LMS (same LMS & host computer with a different IP).

Haha, magically, it's working again, but I didn't touch anything.
Thanks, I will check the IP when it happens again!
Then I will assign a static IP.

Best,

Okay, yesterday I noticed a message popping up on my Boom saying something like "programming Xilinx".
Shortly after that, the Boom rebooted and failed to connect.
Today it connected again by itself.

Is this an automatic firmware update?
I didn't trigger any update manually.

I have exactly the same situation, Boom periodically reboots and fails to connect.

take a look at this thread: https://forums.slimdevices.com/showt...light=andybflo

I don't have any problems with my boom connecting, but it appears this is a possible solution for a couple members. Don't get confused by the "community firmware" reference, its a mixup.

Thanks, I checked the option "fast roaming" in my unifi controller that is mentioned in the link, but it is turned off.
