APU1: No network with 26.7.3

[iam]

Hi,

after upgrading to 26.7.3 my APU1 has no network connection. ping fails from inside and outside. The plugin os-realtek-re is installed.

I booted a snapshot with 26.7.2_2 and have a working setup for now.

Any idea what is causing trouble? Maybe the plugin os-realtek-re does not work on 26.7.3?

Best,
Stefan
