If your wireless station cannot communicate with a computer in the Ethernet LAN when
configured for Infrastructure mode, check the following:
• Make sure the access point that the station is associated with is powered on.
• If you still can’t connect, change the access point and all the stations within the BSS to
another radio channel.
• For a station with roaming disabled, make sure the SSID is the same as that used by
the access point, or the same as that used by the access points in the extended service
set (ESS.)
