I decided to install Manjaro (kde) on my x250 today in order to dual boot with macOS Mojave. The install went fine, but I couldn't access the internet. However, right before the end of the install, my touchpad stopped working. When I rebooted, I was able to use my touchpad for about 20 seconds, before it stopped working. I installed the recommended drivers for my WiFi card (dw1560/BCM4352), and I could see the WiFi card itself using nmcli, but it couldn't see any networks at all. How can I get both the touchpad and wifi working so that I can use my laptop?
You should really split this into two separate topics.

Try this procedure to see if your wifi is initialized properly.
Login to the terminal as root.
In terminal enter:
su
Enter your root account password.
Then paste the following group of commands in the terminal and execute:
sudo nmcli networking off
sleep 2
sudo systemctl stop NetworkManager
sleep 2
sudo ip link set wlp3s0 down
sleep 2
sudo modprobe -r b43
sudo modprobe -r b43legacy
sudo modprobe -r ssb
sudo modprobe -r brcm80211
sudo modprobe -r brcmfmac
sudo modprobe -r brcmsmac
sudo modprobe -r bcma
sudo modprobe -r wl
sudo rfkill unblock wifi
sleep 2
sudo modprobe wl
sleep 2
sudo ip link set wlp3s0 mode default
sleep 2
sudo ip link set wlp3s0 up
sleep 2
sudo systemctl start NetworkManager
sleep 2
sudo rfkill unblock wifi
sleep 2
nmcli r wifi on
sleep 2
exit
Please post the inputs and outputs of all commands.
Somehow that fixed my touchpad, which works perfectly now. However, it also caused the Ethernet port to stop working. nmcli still shows the port, but it can't connect to anything. The only output from any of the commands was:
sudo modprobe -r brcm80211
modprobe: FATAL: Module brcm80211 not found.
The script is designed to stop your ethernet connection and bluetooth as they can conflict with your wifi. If you reboot your ethernet will be up again.
Was there no change in your wifi status at all.
I don't think anything in that script should affect your touchpad functions.
Reboot and test the status of everything again.
After you reboot, could you please post the full unedited input/outputs from:
lsmod
sudo rfkill list all
Just FYI, when I request full inputs and outputs that is what I mean. I do not want a summary of a list of commands. For troubleshooting purposes I need to see all inputs and outputs requested.
I rebooted, but I still can't connect to any networks via Ethernet or wifi. The link leds come on on the ethernet port but the network GUI won't let me connect to the Ethernet connection, and nmcli won't let me connect either. rfkill reports that nothing is soft or hard blocked
If you give me a summary one more time we're done working on this. Full inputs and outputs are required. Is that understood.
What was the status of your trackpad after a reboot.
You need to start providing better details.
What is the status of your wifi.
Is the wifi connection present in the GUI.
Can you see network connections in the GUI.
Can you ping anything over wifi either inside your local network or outside (google).
The trackpad was working, but it suddenly stopped working after the reboot. Wifi is not working. I have the option of turning on/off the wifi, but I still can't see any networks. I added a wifi and ethernet via the gui, and was able to restrict the device for the wifi connection to my wifi card and restrict the device for my ethernet connection to my ethernet nic. I can't ping anything (local or otherwise) via my wifi or ethernet connections.

You say your network ethernet connection was working, yet in your inxi output your ethernet connection was down. Your inxi output is in contradiction to what you are telling me.
The Ethernet adapter you have is currently experiencing issues in Linux. Perhaps installing and testing kernels 4.14 and kernel 4.9 might be helpful to see if a different kernel improves things.
Do you urgently need bluetooth.
Run these commands:
sudo nmcli networking off
sleep 2
sudo systemctl stop NetworkManager
sleep 2
sudo ip link set enp0s25 down
sleep 2
sudo modprobe -r e1000e
sleep 2
sudo modprobe e1000e
sleep 2
sudo ip link set enp0s25 up
sleep 2
sudo systemctl start NetworkManager
sleep 2
nmcli r networking on
Yes, the Ethernet did stop working. After switching to kernel 4.14.85 lts and running the last set of commands you gave me, Ethernet is working again, but wifi still doesn't work, and the touchpad stopped working again. I don't need Bluetooth urgently, but it seems like it's working from what I can tell.

[connor@connor-x250-manjaro /]$ sudo nmcli networking off

[connor@connor-x250-manjaro /]$ nmcli networking on
Please do this.
The best method to disable bluetooth is to add the following entry to the configuration file:
/etc/modprobe.d/blacklist.conf
Add this line to the conf file:
install bluetooth /bin/false
Save the changes to with root privileges, and exit your text editor.
Alternately:
To prevent bluetooth from starting without having to edit a configuration file issue this command:
sudo echo 'install bluetooth /bin/false' | sudo tee -a /etc/modprobe.d/blacklist.conf
Next we must disable the bluetooth service:
sudo systemctl stop bluetooth
sudo systemctl mask bluetooth
Then, restart.
That should completely disable bluetooth, disabling any bluetooth related modules or service. You can easily enable bluetooth again (do not do this unless I ask you to) by commenting out (or remove) the entry in /etc/modprobe.d/blacklist.conf, and then re-enable/unmask the Bluetooth service.
To enable the bluetooth service:
sudo systemctl unmask bluetooth
sudo systemctl enable bluetooth
Then, restart.
Check all functions again, including trackpad.
After reboot please post again:
lsmod
Ethernet is still working, wifi is still not working, touchpad is not working, bluetooth is not working.

@tbg - the OP is booting MacOS Mojave on a Lenovo, ask him what boot loader is the default 
You will sit here all day when probably some combination of his Clover Boot resets the CMOS and other stuff ...

The default is grub, not clover.
Please post the output of tbe following command:
hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | grep -v "Config Status"
That's all above my pay grade @bogdancovaciu, I have as little use for macs as I have for windows.

There appears to be a link, but I can't connect to a wifi network, even if configured manually:
[connor@connor-x250-manjaro /]$ nmcli c up school -a

It's possible your router settings are preventing a connection, as well as many other things. Try these.
Disable MAC Address Randomization in NetworkManager.
This is one of the fixes that sometimes helps get a connection.
Try this:
Disabling MAC address randomization may sometimes be required to obtain a connection. MAC address randomization is enabled by default in Network Manager. It may be disabled by adding the following lines to /etc/NetworkManager/NetworkManager.conf
[device]
wifi.scan-rand-mac-address=no
Save the changes and reboot your router and computer.
Network connection is unreliable, not working, or not connecting.
Occasionally, Network Manager updates change the underlying settings structure (schemas). This can change or break existing settings without you knowing about it.
This can be fixed by removing the existing connection settings, and then re-adding the connection. You may also need to reboot.
Manually delete your network connection in Network Manager.
After the connection is deleted, then recreate your wifi connection in network manager.
Then, edit the connection properties in Network Manager.
There should be several options that can be selected:
"Automaticly connect to this network when it is available"
Below that you should see another option:
"All users may connect to this network"
Ensure that both of these options are checked.
In the IPv6 settings, set the connection to ignore IPv6.
Go through your router configuration by following this guide.
