https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=246031 Bug ID: 246031 Summary: Using regulatory domain FCC4 disables 5Ghz networking Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: tsparks@minions.com I was setting up a laptop with FreeBSD 12.1-RELEASE and the installer set the regulatory domain to FCC4, I noticed it didn't show any 5Ghz networks. I switched it to FCC3, and suddenly there were 5Ghz networks. I thought it might be a driver bug specific to iwn but it turns out that it happens on my RPI3 with a ral USB nic. I mentioned this to a friend who's very familiar with WiFi stuff on FreeBSD and he mentioned that this sounded like a channel list issue. I also realized finding info/documentation about the regulatory domain stuff on FreeBSD was hard, so I just started digging into the source tree. I read through src/lib/lib80211/regdomain.xml and I noticed the stanza for FCC4 had no entry for <netband mode="11na"> wheras FCC3 had an entry. -- You are receiving this mail because: You are the assignee for the bug.help
