Employees in an office are experiencing intermittent wireless connectivity that is affecting their ability to maintain remote desktop sessions. The issue seems to occur sporadically throughout the day and is not isolated to any specific workstations. What should a technician investigate FIRST to troubleshoot this issue?
Change the TCP/IP configuration settings on the affected workstations.
Update the firmware on all the wireless access points immediately.
Conduct a site survey to check for external interference affecting the wireless channels.
Replace the network interface cards (NICs) in the computers losing connectivity.
Wireless connectivity issues that are erratic and affect multiple users typically indicate an environmental or infrastructure-related problem, strongly pointing to interference from external sources or possibly an overloaded wireless access point (AP). A technician should first check for interference or saturation in the wireless channels being used, which could cause intermittent disconnections, by conducting a site survey to identify the presence of interference from other wireless networks or devices operating on the same channel. Issues specific to hardware or TCP/IP configuration would more likely produce consistent or isolated connectivity failures, rather than widespread and random ones. A firmware upgrade should only be considered if the issue is known to be resolved through such an update.
