Firmware Version Affected
3004.388.6_2-gnuton0_alpha1_tuf

Is this bug present in upstream Merlin releases too?
YES can't remember that this hasn't been there.

Describe the bug
My Weatherstation disconnects very frequently. Every 20-40 seconds.
Also i don't know, if this also related. My phone is connected to wifi, but the symbol is flashing with a "!" inside and no data is flowing.
Wifi off/on helps to get rid of that.

Weather Station is a Bresser 4Cast Pro Wifi
Phone is a Pixel 7 Pro

To Reproduce
Can't activly reproduce.
The weatherstation bug is always there.
and the phone bug happens when i switch on my FireTV Stick, TV and AV Receiver!?

If you need more information i would be glad to help. Please be gently with me, it's my first bug report.

Expected behavior
No connection drops.

I just want to add some news. The problem with my phone is gone. The reason was my FireTV stick. When this connected to my Wifi, my phone got the described behavior with no connection to my network. Since the FireTV stick is connected via LAN, the problem is gone.

Whats still happening is the connection drop from my weather station. Every ~20 sec a reconnect...
I'm going to believe, that the Station itself is buggy....
