[Kernel-packages] [Bug 1862760] Re: Unreliable 802.11ac connection on our raspi images
Hi all, I found that adding the correct region to the /etc/default/crda file resolved my 5GHZ woes on the raspi4b ubuntu 20.10. After a reboot it finally connected to my 5GHZ network. Just putting this out there if it helps anyone. -- 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-raspi package in Ubuntu: New Status in linux-raspi2 package in Ubuntu: New Status in netplan.io 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 netplan.io source package in Bionic: New Status in linux-firmware source package in Eoan: Won't Fix Status in linux-firmware-raspi2 source package in Eoan: Won't Fix Status in linux-raspi2-5.3 source package in Eoan: Won't Fix Status in netplan.io source package in Eoan: Won't Fix Status in linux-firmware source package in Focal: New Status in linux-firmware-raspi2 source package in Focal: Triaged Status in linux-raspi source package in Focal: New Status in netplan.io 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.

[Kernel-packages] [Bug 1319443] Re: 046d:082d Logitech c920 usb webcam not working when plugged into USB 3.0 port
Just FYI I have the same issue, and unfortunately no USB 2.0 port. Lowering the resolution does work, but I would like to use 720p at least. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1319443 Title: 046d:082d Logitech c920 usb webcam not working when plugged into USB 3.0 port Status in linux package in Ubuntu: Triaged Bug description: My logitech c920 usb webcam doesn't work when connected to my usb 3.0 host controller (Etron EJ168a).
