Troubleshooting Tips

  • Root privileges are required to complete these steps.
  • Turn wireless connection OFF and back ON.
  • Install all driver updates and patches.

Note: You can check the wireless card manufacturer's website for any available updates or patches.

  • Modify MWireless settings

Note: Some Linux distributions require the intermediate CA certificate that was used to sign the RADIUS server certificate instead of / in addition to the Root CA certificate. You can download the 2024 InCommon RSA Server CA intermediate certificate ( or 2038 USERTrust RSA Certification Authority root certificate) and save the file to a location where it will not be deleted (e.g., ~/ or ~/Documents/)

  1. Click Settings from the System menu.
  2. Click the gear icon for MWireless.
  3. Check the Connect Automatically box.
  4. Click the IPv4 tab and verify that IPv4 Method is set to Automatic (DHCP).
