section Using the Belkin Wireless LAN Utility (f) Client IP Address 1 Shows the IP address of the computer. The IP address is obtained automatically by default. You may set the IP address manually through Windows Networking Properties. 2 (g) Network Connection Type Shows the current wireless mode the Card is operating in. There are 3 two operating modes: Infrastructure and Ad-Hoc. Infrastructure is the most common mode to operate in. Infrastructure mode is used when connecting your PC to a wireless router or a wireless access point. 4 Ad-Hoc mode is used to connect two or more computers together without the use of a wireless router or an access point. 5 (h) Radio State Shows whether the radio of your wireless client is enabled or disabled. 6 (i) Signal Displays the wireless signal strength in decibels (dBm). The decibel 7 scale is negative, so smaller absolute values correspond to stronger signals (i.e. -20 dBm is stronger than -80 dBm). The signal to noise ratio (SNR) is the difference between the signal and the noise (e.g. 8 if the noise is -80 dBm and the signal is -20 dBm, the SNR is 60 dB); the larger the SNR, the better. In general, connections should 9 have an SNR greater than 20 dBm, or the user may experience poor reliability and/or performance. If the signal is less than -50 dBm, the user should consider repositioning their workstation Wireless Router 10 or Access Point, rotating the Wireless Router or Access Point's antennas, or Limiting their Transmission Rate (described on page 38 of the troubleshooting section of the manual), to ensure a reliable wireless connection. (j) Noise Displays the intensity of the external noise, on this wireless channel, in decibels (dBm). If the noise is greater than -70 dBm, the user should consider changing the wireless channel used in their Wireless Router or Access Point, to ensure a reliable wireless connection. 29
