Fortunately, you can reset your network settings easily on iOS devices. For example, if you own an iPad or iPhone, you can go to Settings > General > Reset and then Reset Network Settings. Unfortunately, however, unlike iOS, for Macs we don’t have an equivalent feature to do the reset but there are workarounds, you can delete the WiFi interface, which in return remove all previous networks connected and its settings.
Method 1: Remove and add the Wi-Fi interface
Erase the Wi-Fi interface, please make sure that Wi-Fi is selected on the sidebar. Once done, click the minus (-) sign just below the left corner of network preferences to remove it. Once you remove the interface, you can then create a new one to add your WiFi network. After you remove it, click + then on the Interface dropdown, select Wi-Fi then click Create. Once done, click Apply. Here is how:

- Empty the Trash. Do not worry. Your Mac will recreate all new preference files for wireless networking.
