[Touch-packages] [Bug 1960817] [NEW] Network Manager sets powersave on by default, thus making many WiFi connections unreliable
Public bug reported: As the headline says. On the support fora that I frequent, many people report unstable and unreliable WiFi connections because of this. In those cases, when power management for the WiFi chipset is turned off, the connection immediately improves a lot. Therefore the default for WiFi power management should be "off", non "on". Workaround for those who don't want to wait for the fix: sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf Reboot. When there's no such .conf file yet: sudo touch /etc/NetworkManager/conf.d/default-wifi-powersave-off.conf echo "[connection]" | sudo tee /etc/NetworkManager/conf.d/default-wifi- powersave-off.conf echo "wifi.powersave = 2" | sudo tee -a /etc/NetworkManager/conf.d/default-wifi-powersave-off.conf Reboot. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: instability management networkmanager power wifi -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1960817 Title: Network Manager sets powersave on by default, thus making many WiFi connections unreliable Status in network-manager package in Ubuntu: New Bug description: As the headline says.

[Touch-packages] [Bug 1835660] Re: initramfs unpacking failed
This is a simplified version of the means to work around this problem: Step 1: sudo sed -i 's/COMPRESS=lz4/COMPRESS=gzip/g' /etc/initramfs-tools/initramfs.conf Step 2: sudo update-initramfs -u Step 3: Reboot. Now I wonder whether someone has already tried something other than gzip? Because initramfs.conf mentions no less than six options: # COMPRESS: [ gzip | bzip2 | lz4 | lzma | lzop | xz ] Apparently gzip is slower than lz4, which might slow the boot process by several seconds. One of the other alternatives might be faster. Of course I could test that myself, but I'm too lazy today, so I'm hoping somebody else has done the footwork already -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed Status in initramfs-tools package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Bug description: "initramfs unpacking failed: Decoding failed", message appears on boot up. If I "update-initramfs" using gzip instead of lz, then boot up passes without decoding failed message. --- However, we currently believe that the decoding error reported in dmesg is actually harmless and has no impact on usability on the system. Switching from lz4 to gzip compression, simply papers over the warning, without any benefits, and slows down boot. Kernel should be fixed to correctly parse lz4 compressed initrds, or at least lower the warning, to not be user visible as an error.
