Troubleshooting Wi-Fi Connection
The following terminology is used in this troubleshooting section:
• Router Signal Strength (RSSI). RSSI is an indication of the signal
strength of the Wi-Fi router being received by the scanning device (i.e.,
smart phone). Therefore, the higher the RSSI number (or less negative
in some devices), the stronger the signal..
• 802.11b, g and n are wireless networking specification that extends
throughput up to 130mbps using the 2.4 GHz band.
• Internet Protocol Address (IP address). This is a numerical label
assigned to each device (e.g., computer, printer, thermostat)
participating in a computer network that uses the Internet Protocol for
communication. An IP address serves two principal functions: host or
network interface identification and location addressing.
