[Bug 1894867] Re: WiFi works on kernel version LL 115 but not LL 117
Since that time, I determined that the cause of this problem is that I have two kernels for each kernel release: lowlatency and generic. The upgrade puts the headers in for generic whether I am running lowlatency when the silent upgrade takes place or do the upgrade in a terminal window by hand. Therefore, the upgrade does not check to see if I have the same release in both lowlatency and generic. I have to remember to install the headers for lowlatency after any kernel update. Since the header update includes virtualbox updates I analyze that this solves the failed WiFi and Virtualbox corruption I found before I realized the headers were not up to date. The failed WiFi and Virtualbox were disguised because I could boot partially with previous low latency headers but not correctly. The ethernet hid the WiFi problem. I recommend that upgrades for kernels and headers be scripted for when both lowlatency and generic (when present). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894867 Title: WiFi works on kernel version LL 115 but not LL 117 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Same fix worked again. Must be a problem in the upgrade script. I noticed that the header files were pulled in with the broken wifi original upgrade (which usually does not happen and I have to do that after the upgrade). When I just did the reinstall of the upgrade the install of the kernel complained I had no header files. I therefore reinstalled them also. Now all WiFi works. Have not checked anything else yet.

Same problem again with update (manual this time) kubuntu 18.04 update to "Ubuntu 4.15.0-123.126-lowlatency 4.15.18" deletes WiFi but Ubuntu 4.15.0-122.124-lowlatency 4.15.18 works wifi correctly. ** Attachment added: "some variations between wifi working and wifi not-working kernels" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894867/+attachment/5433980/+files/Ubuntu-4.15.0.122-lowlatyency-4.15.18.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894867 Title: WiFi works on kernel version LL 115 but not LL 117 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1894867] Re: WiFi works on kernel version LL 115 but not LL 117
Problem Solved: I fixed the issue with: sudo apt-get install --reinstall linux-image-4.15.0-117-lowlatency sudo apt-get install --reinstall linux-headers-4.15.0-117-lowlatency sudo apt-get install --reinstall linux-image-4.15.0-117-generic What I saw was that VirtualBox was also corrupt in the 117 O/S but not in the 115 version. The solution above fixed the WiFi and VirtualBox. Please note that I generally do not like using Discover to run updates. I prefer: sudo apt update sudo apt upgrade Sometimes Discover locks updates from the command prompt, and I have to kill the locks. Discover takes a long time to do updates. I thought the "silent upgrade" was a new feature of Discover. The "bot" upgrade was something new to me, and now I think that it might be a security problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894867 Title: WiFi works on kernel version LL 115 but not LL 117 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
