Master Wireless Upgrades with LinkIQ^TM Duo Cable Network Wi-Fi Tester

Verify Your Network Settings

Once you’ve confirmed the cable plant can handle the speed and PoE demands of your new Wi-Fi APs, LinkIQ Duo provides key network insights to help you ensure the right switch port and configuration. Using LLDP or CDP, LinkIQ Duo displays the switch’s name, its advertised speed, the specific port number and the virtual LAN (VLAN) assigned to a link. You can even identify the connected switch port using the tester’s Blink Port Light feature.

LinkIQ Duo also allows you to perform an IP ping test to confirm whether links can reach a specific target address, ensuring your wireless controller or gateway is operating and accessible. The IP ping test also provides valuable latency information, calculating the average response time from four pings to your target.

Optimize Your Wireless Environment

After successfully installing your Wi-Fi APs, LinkIQ Duo becomes your ultimate tool for fine-tuning your wireless environment across the 2.4, 5 and 6 GHz frequency bands, supporting all Wi-Fi generations up to Wi-Fi 6E.

The intuitive interface on the LinkIQ Duo displays all available Wi-Fi networks (SSIDs), along with their signal strength, security status, radio frequency bands and the number of APs. You can home in on a specific AP (by name or MAC address) to view all the networks it supports, its security status, country code and detailed information for each of its radios, including frequency and primary channels. The tester even alerts you to potential issues such as weak encryption or irregular channels. For each AP radio, you can dive even deeper to see channel bandwidth, channel range and channel utilization. Running a Wi-Fi connection test with LinkIQ Duo provides immediate insight into signal strength, transmit and receive rates for specific radios, helping you assess real-world performance. You can conveniently save your results on the LinkIQ Duo or export them to Fluke Networks LinkWare™ PC software for storage and easy report generation.

Where the LinkIQ Duo truly shines is in its unique graphical display, which shows channel utilization, signal strength and interference for in-range APs across all three frequency bands. For each frequency, APs are positioned on the graph based on their channel and signal strength. A signal strength of -50 dBm or higher is optimal for voice, data and video transmission. The graph also clearly displays channel utilization for each channel. Ideally, this should be below 50 percent to ensure your Wi-Fi isn’t bogged down by too much traffic. The “Channel Overlap” option shows you the range of channels for each AP, so you know if multiple APs in the same area are operating on overlapping channels. This is crucial for identifying and mitigating co-channel or adjacent channel interference, which can degrade performance by causing APs to essentially “talk over” each other.

By equipping you with extensive information about your Wi-Fi networks, channels, APs and radios, LinkIQ Duo empowers you to determine the absolute best settings for your new APs. Suppose channel utilization is too high or too many radios in the area are operating on overlapping channels. In such cases, you may need to change the channel of an AP radio or decrease its transmit power to focus coverage on a smaller area and prevent interference.
