A network administrator has received complaints about erratic connection quality on the office's wireless network. The issues predominantly occur during business hours and seem less frequent in the evening. There have been recent installations of industrial equipment within the building that operate only during business hours. Which measure should the administrator take first to address the potential source of the wireless connectivity problems?
Modify DHCP lease time settings to ensure IP address conflicts are not causing the issue
Perform an environmental survey to identify if the new industrial equipment is a source of interference
Change the operation frequency channel of the wireless access points to avoid overlap with other WiFi networks
Inspect cables and connectors associated with wireless access points for any signs of damage
