Public bug reported: My wifi is no longer working since a recent update (yesterday, I think). When typing “ifconfig -a”, I get (among other connections), the following one, which seems to correspond to my wifi card:
```bash wlp59s0: flags=4098<BROADCAST,MULTICAST> mtu 1500 ether 5c:87:9c:fa:81:c9 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` I thus tried to switch it on, but I get the following message: ```bash $ sudo ifconfig wlp59s0 up SIOCSIFFLAGS: Input/output error ``` This error message is not really helpful: I would have expected ifconfig to provide a more user-friendly explanation about what is not working well. Other commands that might be relevant: ```bash $ iwconfig lo no wireless extensions. enp0s20f0u1 no wireless extensions. wlp59s0 IEEE 802.11 ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on $ rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ sudo ip link set wlp59s0 up RTNETLINK answers: Input/output error ``` I’m calling apport-collect on this bug to add other relevant information. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.9 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Dependencies: gcc-8-base 8.3.0-6ubuntu1~18.04.1 libc6 2.27-3ubuntu1 libgcc1 1:8.3.0-6ubuntu1~18.04.1 libpcre3 2:8.39-9 libselinux1 2.7-2build2 DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-bionic-amd64-20180608-47+berlinetta-cfl-r+X77 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2019-08-28 (106 days ago) InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20180608-09:38 Package: net-tools 1.60+git20161116.90da8a0-1ubuntu1 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.15.0-1065.75-oem 4.15.18 Tags: bionic Uname: Linux 4.15.0-1065-oem x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True ** Affects: net-tools (Ubuntu) Importance: Undecided Status: New ** Tags: apport-collected bionic ** Tags added: apport-collected bionic ** Description changed: My wifi is no longer working since a recent update.
