Unable to connect to Eduroam WLAN: WiFi Username remembered on MAC

WIFi (WLAN) is a wireless network protocol based on the IEEE 802.11 family of standards. They are commonly used for local area networking of devices and Internet access. Wi-Fi uses multiple parts of the IEEE 802 protocol and is designed to interwork seamlessly with its wired Ethernet. Below is a brief difference between WLAN and WIFI. Here are some articles I have written relating to MacBook “how to set up external displays on your Mac and arrange your display in Mac, and how to enable or disable automatic software updates on Mac“.

Wireless Local Area Network and stands for a wireless local network that enables you to connect your devices such as laptops to the Internet without cables. WLAN is the umbrella term for this wireless technology. WiFi refers to a type of WLAN that stands for an issued certificate according to the IEEE 802.11 standard. Some countries refer to this technology differently and here in Germany, WLAN is popularly used while in Nigeria, WiFi is widely used.

In Windows, this is a little bit easier, but a little bit complicated on MAC. I wanted to connect to Eduroam, but my previous credential (username) was always prompted even when I entered a new username and password.

I had to delete the SSL certificate from my keychain access and this worked. The reason might be the certificate has expired and unless you delete the old one, you may never be able to replace the old one. Here are the steps needed in administering SSL on MAC OS’.

From the Finder
- click Go 
- Click on Utilities 
- Click on KeyChain Access
This will open the Certificate Store as shown below
- In the left pane, 
- Click on the certificate that you wish to delete.
- In the menu bar, click on Edit 
- Click on Delete.

Note: You may be prompted for confirmation in order to complete the change by entering your password to modify the keychain. After this step, you should be able to login with your new credentials without having any issues.
