联想ThinkPad E580安装Ubuntu 16.04时WIFI无法使用，求驱动解决方案
Hey there, let's get that WiFi working on your ThinkPad E580. I've troubleshooted this exact adapter a few times, so here's a step-by-step guide tailored to your setup:
First, confirm your adapter details (optional but helpful)
Even though you know the model, it's good to verify the device ID to be 100% sure. Run this command in the terminal:
lspci -nn | grep Network
You should see output like 03:00.0 Network controller [0280]: Intel Corporation Wireless 3165 [8086:3165] — the 8086:3165 is the key ID for this adapter.
Step 1: Update your system and firmware
Since you have working wired internet, start by updating all packages to ensure you have the latest system components:
sudo apt update && sudo apt upgrade -y
Next, install (or reinstall) the Linux firmware package that includes Intel WiFi drivers:
sudo apt install --reinstall linux-firmware
Step 2: Reload the WiFi driver module
The Intel 3165 uses the iwlwifi kernel module. Let's restart it to apply any firmware updates:
sudo modprobe -r iwlwifi && sudo modprobe iwlwifi
After running this, check if your WiFi network appears in the system tray.
Step 3: Check for soft/hardware blocks
Sometimes WiFi gets disabled accidentally. Run this command to check:
rfkill list
If you see Soft blocked: yes next to your wireless adapter, unblock it with:
sudo rfkill unblock all
Also, double-check your ThinkPad's physical WiFi switch (usually on the side) or use the Fn+F5 shortcut to make sure WiFi is enabled.
Step 4: Upgrade your kernel (if the above steps fail)
Ubuntu 16.04's default 4.4 kernel might have limited support for newer adapters like the 3165. Install the Hardware Enablement (HWE) kernel to get a more recent version:
sudo apt install linux-generic-hwe-16.04
Once installed, restart your laptop. The newer kernel should have better support for your WiFi adapter.
After following these steps, your Intel 3165 AC WiFi should be up and running. If you still run into issues, share the output of the lspci and dmesg | grep iwlwifi commands, and I can help dig deeper.
