Why each option
After replacing a WLAN card, all previously saved wireless network profiles are lost, so the technician must add the network SSID to establish a new connection.
The security passphrase on the network does not need to be changed just because the client adapter was replaced; that would affect all other connected devices unnecessarily.
Router encryption configuration is independent of the client laptop's hardware replacement and should already be configured.
Replacing the WLAN card installs a new hardware component with no previously saved network profiles. The Windows wireless network manager stores connection profiles (SSID, security type, passphrase) tied to the adapter, so a replacement card starts with no known networks. The technician must select or manually enter the network SSID and provide credentials to reconnect. The card is already confirmed working in Device Manager, so driver or firmware issues are not the next concern.
Updating firmware and drivers is a best practice but is not the immediate next step when the device is already listed as enabled and working in Device Manager.
