http://bugzilla.opensuse.org/show_bug.cgi?id=1127617 Bug ID: 1127617 Summary: hostapd unable to set up 5GHz WiFi network in Switzerland Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: bnc-team-screening@forge.provo.novell.com Reporter: seroton10@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 798640 --> http://bugzilla.opensuse.org/attachment.cgi?id=798640&action=edit my hostapd configuration Since a recent software update (with zypper up, at the end of February), hostapd is unable to set up a 5GHz WiFi access point. I have attached my hostapd.conf file, the one that produces this error, as well as a diff of my changes relative to a pristine hostapd.conf file. A temporary work-around is to change the country code from CH (Switzerland) to FR (France) or DE (Germany) - both work for me. Earlier, when it worked, hostapd produced log entries like this when starting: Feb 20 16:19:55 winti systemd[1]: Started Hostapd IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator.
