You’ll need to install the proprietary Broadcom driver packages. Assuming that you have a wired ethernet connection available, subscribe to the Packman repo, then install the ‘broadcom-wl-kmp-default’ and ‘broadcom-wl’ packages.
Thanks Deano, tinylagarto. That worked well.
Remark: Installation choosed Networkmanager. In contrast to my Desktop, where ‘wicked’ had been choosen. Don’t mind. Wicked has no Systemtray, what I miss a bit on the Desktop.
I’ve found that ordinarily “iw” shouldn’t be essential for wireless although for some manual configurations and connections (WEP and open AP) can be a great convenience.
All WiFi Access Points today should either be open or be configured with WPA/WPA2, all which are supported by wpa_supplicant which is installed in all openSUSE regardless whether wireless is available or used or not.
