Found a fix : Get into Bios (F2 At boot) Go to : Power Management -> Wireless Radio Control -> Turn everything OFF This prevents hardware lock of wifi card when going into suspend and undocking from Dell dock. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947558 Title: rfkill fails to turn on wifi card on Dell Latitude 5490 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1947558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1947558] Re: rfkill fails to turn on wifi card on Dell Latitude 5490
Note : it might be a problem in the ilwifi driver. I am not sure. Perhaps rf-kill does the block properly on suspend But fails to unblock the card because the ilwifi driver does not bring it back from "hardware lock" to "available" on resume. So I am not sure of where the problem is, but I tend to think that it's a ilwifi problem :/ https://bugs.launchpad.net/ubuntu/+source/backport-iwlwifi- dkms/+bug/1947561 How can I make sure rfkill does ask properly to the kernel/module to unlock the hardware wifi card, and confirm this is a ilwifi problem ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947558 Title: rfkill fails to turn on wifi card on Dell Latitude 5490 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1947558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
