Spitz AX (GL-X3000) WiFi Issues

Dear people,

I am operating a Spitz behind a Brume 2. I have severe WiFi Issues with the Spitz resulting in complete packet loss for ~3-5 seconds every like 10 minutes or so. The Spitz does have a SIM card installed (as a failover option) but atm, I have deactivated it for examining the issue.

I have narrowed down this issue to be definitely located at the Spitz because if I connect via cable to my cisco switch (and thus to the Brume 2), the connection is stable the whole day without any packet loss whatsoever.

The Spitz does use the latest fw:

Additional Info:
MacBook Pro M1
I am using 5GHz WiFi on automatic Channel

Is this a known issue with the Spitz?

Thanks in advance

I have no issues over 5GHz WiFi.

Good to know. But that actually does not solve my issue…

Try to deactivate the automatic channel selection and use fixed channel on non- DFS frequencies.
Channel 38 or 46 with 40 MHz BW or channel 42 with 80 MHz BW.

Thanks @WolfP
I will try it!
