Summary ​

This article guides you through fixing common issues that prevent personal smartphones from connecting to secure corporate Wi-Fi networks (often labeled as "Guest" or "BYOD" networks).

Symptoms ​

  • Your phone asks for a password but repeatedly says "Incorrect password" even when typed correctly.
  • The phone connects to the Wi-Fi but displays a "No Internet Connection" warning.
  • Your iPhone prompts you to "Trust a Certificate" and the connection fails if you decline.

Prerequisites ​

  • You must know your current corporate username and password.

Instructions ​

1. Trust the Security Certificate (iPhone/iPad) ​

  1. Corporate Wi-Fi networks use special security certificates to verify your identity.
  2. Go to Settings > Wi-Fi and tap your company's network name.
  3. Enter your corporate username and password (the same one you use for your computer).
  4. A screen titled Certificate will appear. Look at the top right corner and tap Trust.
  5. Your phone should now securely connect to the network.

2. Configure Advanced Settings (Android) ​

  1. Android phones sometimes require you to manually specify the security type for corporate networks.
  2. Go to Settings > Connections > Wi-Fi and tap your company's network name.
  3. If prompted for an EAP method, select PEAP.
  4. If prompted for Phase 2 authentication, select MSCHAPV2.
  5. Change the CA certificate dropdown to Use system certificates or Do not validate (depending on your IT department's specific policy).
  6. Enter your corporate username in the Identity field (leave Anonymous Identity blank).
  7. Enter your password and tap Connect.

3. Forget and Reconnect the Network ​

  1. If you recently changed your corporate password, your phone will fail to connect because it is trying to use the old password.
  2. On your phone, go to your Wi-Fi settings, tap the information icon (i or gear) next to the network name, and select Forget This Network.
  3. Tap the network name again and log in with your new password.

4. Verify Success ​

  1. Open a web browser on your phone and try loading a public website (like google.com) to confirm you have internet access.

WARNING

Many corporate Wi-Fi networks are set up as "Captive Portals". This means that even after connecting, you must open a web browser and accept the Terms and Conditions before the internet will work.
