Generally speaking we don't know what country a device is operating in, so we default to the world domain which should be safe throughout the world. The AP may send a hint to the client as to what regulatory domain to use, but many APs do not do this.
Also note that on many desktop systems now the regulatory domain is managed by the wireless card firmware, which is why you may see the domain set there even if the AP does not send a hint. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1862760 Title: Unreliable 802.11ac connection on our raspi images Status in linux-firmware package in Ubuntu: New Status in linux-firmware-raspi2 package in Ubuntu: Triaged Status in linux-raspi2-5.3 package in Ubuntu: New Status in linux-firmware source package in Bionic: New Status in linux-firmware-raspi2 source package in Bionic: New Status in linux-raspi2-5.3 source package in Bionic: New Status in linux-firmware source package in Eoan: New Status in linux-firmware-raspi2 source package in Eoan: New Status in linux-raspi2-5.3 source package in Eoan: New Status in linux-firmware source package in Focal: New Status in linux-firmware-raspi2 source package in Focal: Triaged Status in linux-raspi2-5.3 source package in Focal: New Bug description: We were not able to completely pin-point the issue yet, so this is more of a blanket bug for the current issues we are seeing. We don't know where exactly the issue can be located. While preparing and testing 18.04.4, certification reported issues with our uc18 images on the pi4 with wifi ac tests. One of our engineers (Brian) confirmed it locally with a wifi access point restricted only to 802.11ac. After some additional testing, he noticed that he had the same unreliable symptoms for both the classic and core images, as well as the 19.10.1 classic images. The symptoms seem to vary, from inability to detect 802.11ac APs, inability to connect and/or receive an IP address and no traffic getting through. We will provide all the information that we have. Raspbian works better in this regard. We have pulled in the wifi firmware bits from Raspbian and using those, and that seems to resolve all flakiness.
