Thank you for your suggestions, You-Sheng Yang. Which kernel/firmware version worked? -> the default Ubuntu 19.04 kernel and firmware. I never installed a kernel or firmware from external sources and all minor updates that were available worked just fine. What also worked: all other versions of Ubuntu I used on my laptop, at least 18.04 and 18.10 too, most probably I also used 16.04 (not sure).
Which kernel/firmware does not work? -> The versions at the release of Ubuntu 19.10 (on the .iso images) and also the latest update (5.3.0-19-generic). An important detail could be, that when I boot Ubuntu 19.10 with the old kernel still installed from 19.04 the same behavior can be seen. $ uname -a Linux whakaari 5.3.0-19-generic #20-Ubuntu SMP Fri Oct 18 09:04:39 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux $ dmesg | grep "iwlwifi\|wlp3s0" [ 4.442485] iwlwifi 0000:03:00.0: Found debug destination: EXTERNAL_DRAM [ 4.442487] iwlwifi 0000:03:00.0: Found debug configuration: 0 [ 4.442790] iwlwifi 0000:03:00.0: loaded firmware version 29.1654887522.0 op_mode iwlmvm [ 4.495202] iwlwifi 0000:03:00.0: Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210 [ 4.509093] iwlwifi 0000:03:00.0: Applying debug destination EXTERNAL_DRAM [ 4.509828] iwlwifi 0000:03:00.0: Allocated 0x00400000 bytes for firmware monitor.
