Missing wlan0
by mcnalu from LinuxQuestions.org on (#5SFYZ)
I just replaced the battery in my laptop and I find that my network interface wlan0 no longer appears in slackware-current and so I cannot connect to a wifi network. The laptop dual boots into windows 10 and in that the wifi is working just fine.
Here's some info on what I'm seeing. Previously ifconfig showed wlan0 and networkmanager was able to connect to various networks with no problem.
Code:# ifconfig -a
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 1980 bytes 154048 (150.4 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1980 bytes 154048 (150.4 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0Code:# lsmod | grep iwlwifi
iwlwifi 299008 1 iwlmvm
cfg80211 1007616 5 iwlmvm,rtlwifi,iwlwifi,mac80211,rtl8xxxuCode:# lspci -vv | grep -i network
03:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)And at the end of the block of lspci -vv for that network controller I find:
Code: Kernel driver in use: iwlwifi
Kernel modules: iwlwifiI can't see any errors in dmesg and using modprobe -r to unload and load relevant modules (iwlmvm and iwlwifi) doesn't make wlan0 appear.
Any ideas would be very welcome.
