I dont thought this thread would get a response. I asked first what information i should provide but did not get any response because in dmesg there is nothing relevant. Its sad that someone else have to say that he have the same issue to get a resposne. I installed ubuntu 18.10 in the meantime on an other device with totaly different wlan chipset. Same issue. So not that even the ubuntu version, also the hardware changed fully.
Scanning via command line: iwlist wlan3s0 scanning wlan3s0 Interface doesn't support scanning. Lets see if this issue wont get touched again until someone reports the same issue with 19.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1769480 Title: Ubuntu 18.04 - networkmanager dont show other wifi after few minutes Status in linux package in Ubuntu: Incomplete Status in network-manager package in Ubuntu: Confirmed Bug description: how to reproduce: dd the iso to an usb drive and boot from it.
