Table 2. Settings on the Tools Menu (continued)
Lets you set options for channels and access point lists.
•
Enable 2.4 GHz band, Enable 5 GHz band: Select one or both frequency bands to see
networks and access points from one or both bands. Both are enabled by default.
In some countries selected channels may not be available.
• Transmit probes: To discover access points, the tester listens for SSID broadcasts on each
channel. The tester can discover only access points that broadcast their SSID while the
tester is on the same channel. For faster discovery, the tester transmits probe request
frames by default to get responses from access points.
Because probes increase channel usage, the tester does not transmit them when you
look at the channel usage screens or when you connect the external antenna.
• Group virtual access points: When an access point broadcasts multiple SSIDs and/or MAC
addresses (BSSIDs), the MACs are virtual access points. Virtual access points can support
different networks from the same physical access point. An access point that uses two
radios to broadcast multiple MACs can support networks on different channels.
When Group virtual access points is enabled, virtual access points show as one access
point in the Access Points list. If the access point broadcasts a name (shown in the Name/
MAC column), the number of SSIDs it supports shows in the SSID column. For example,
"2 SSIDs" shows in the column.
