Just installed DeepIn Linux on my Thinkpad E480. The WiFi seems to be turned on but it cannot find any networks. I believe the network adapter is an AC 3165.

Thanks in advance!

What specifically do you mean by the "WiFi seems to be turned on"?

More and more detailed information is needed. Some of the diagnostics in this post should help: https://www.linuxquestions.org/quest...ux-4175434970/

# rfkill list

It might be blocked in software.

# modinfo iwlwifi

It might have multiple antennae and is selecting the wrong one by default. Or other defaults that do not favor your chipset.

Otherwise:

$ ip link show
$ ip link set wlo1 up
$ iw dev wlo1 scan

May or may not be relevant. But a place to start.

rfkill
command not found
modinfo
command not found
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000
link/ether 8c:16:45:bd:15:a3 brd ff:ff:ff:ff:ff:ff


ip link set wlo1 up
Cannot find device "wlo1"

iw dev wlo1 scan
command not found

Seems like it does not recognise the WiFi adapter. But as I said, it seems to be turned on, meaning that the "switch" in the settings is on as if it worked but just couldn´t finde any networks

You'll probably need to install rfkill, iw, although not sure why modinfo isn't there, but you will need to be root to run modinfo.

But yeah, your wifi doesn't seem to have an interface for it, so it likely doesn't have a driver. Or a loaded module. Or missing firmware.

# modprobe iwlwifi
# ip link show

Perhaps see if it's listed in lsusb or lspci.

$ lsusb
$ lspci -nnk
$ lsmod

For my debian buster...

# apt-get install usbutils pciutils iw rfkill kmod

Also make sure the firmware is present.

# apt-get install firmware-iwlwifi

Or whatever applies to your distro.

# dmesg | grep -i firmware

The thinkpad E480 has a rtl8822BE wifi card, which is in the staging drivers, and was added in kernel 4.14.

the ole' rfkill catch 22 this has got to be the most reconfigured stupidest thing ever invented for Linux to use, RFKILL

you need a program called RFKILL to check RFKILL, and to Modify it if it is blocking anything the lets you get out past your PC in order to install RFKILL so you can check RFKILL to see if it is blocking you from getting outside of your PC so you can install RFKILL to check to see if RFKILL is blocking you from getting outside of your PC so you can install RFKILL to see if RFKILL is blocking you from getting outside of your PC ..... but we all know one has to have a connection to get outside of the PC to install RFKILL to see if RFKILL is blocking you from installing anything ... catch 22

what is worse is most if not all distros do not install the rfkill program in the default installation which they all should. Because lots of times rfkill is the one that is blocking a user from getting outside the PC and need that connection to install RFKILL so they can unblock the connections.
