Thank you for the update Martin, and the good news.
I'll mark this report "Incomplete" for now as the problem appears to
have fixed itself; if however the problem re-occurs, please change the
Status back to "New".
Thank you for uploading your upgrade logs, and for your effort in
helping make Ubuntu better.
Note to any readers: It could be this report is marked against the
wrong package, possibly should be oem-wifi-iwlwifi...

Title:
SIOCSIFFLAGS: Input/output error
Status in net-tools package in Ubuntu:
Incomplete
Bug description:
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.

```
I’m calling apport-collect on this bug to add other relevant information.
