Which of the following is the BEST way to troubleshoot this issue?
Instruct the employee to disconnect and reconnect to the wireless network to refresh their IP address.
Recommend that the employee performs a factory reset on their smartphone to eliminate any potential conflicts.
Advise the employee to switch to a 5GHz network band for better connectivity.
Verify if the device's software is up to date and compliant with the company's security policy.
