首次安装Ubuntu 17.1后Intel Wireless 3160 WiFi频繁断开求助

Hey there, sorry to hear you're stuck with this annoying WiFi drop issue—nothing's worse than losing connection randomly and having to manually reset it every time. Since you're using the Intel Wireless 3160 adapter on Ubuntu 17.1, let's try some hardware-specific fixes that often resolve this exact problem:

• Disable WiFi power management
  Intel adapters are notorious for acting up when power-saving features kick in. To turn this off permanently, run these commands in your terminal:

  sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
  sudo systemctl restart NetworkManager.service
  

  This switches the power save mode from enabled (3) to disabled (2), which should prevent the adapter from shutting down unexpectedly.

• Update Intel wireless firmware
  Ubuntu 17.1 might not have the latest firmware for your 3160 adapter. Install the updated version with:

  sudo apt update && sudo apt install firmware-iwlwifi
  

  Reboot your system after installation to let the new firmware load.

• Tweak NetworkManager's roaming sensitivity
  Aggressive roaming (the adapter jumping between networks too quickly) can cause random disconnects. Adjust this setting by editing the NetworkManager config:

  sudo nano /etc/NetworkManager/NetworkManager.conf
  

  Add this line under the [connection] section:

  wifi.roam-sensitivity=1
  

  Save the file (press Ctrl+O, then Enter) and exit (Ctrl+X), then restart NetworkManager:

  sudo systemctl restart NetworkManager.service
  

  A value of 1 means less aggressive roaming, which helps with stability.

• Reload the WiFi module with bug-fix parameters
  Sometimes the default iwlwifi module settings cause issues for the 3160. Let's reload it with specific parameters to test:

  sudo modprobe -r iwlwifi
  sudo modprobe iwlwifi 11n_disable=1 swcrypto=1
  

  If this stops the disconnects temporarily, make the change permanent by adding the parameters to the module config:

  echo "options iwlwifi 11n_disable=1 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
  

  Reboot your system to apply the permanent fix.

Give these steps a try one at a time, and see if any of them resolve your WiFi issues. Let me know how it goes!
